For those eager to built something more I am posting a new version, with included sensors for temperature and Himidity DHT22 (Pin D4), MQ135 (Pin AI 3), KY-026 IR Flame Sensor (Pin AI 1) it could also be a light sensor LM393, Led (Pin D3), I used LM2596 for 5V which I have taken from 12V power strip. 3.3 V I have taken from arduino UNO. I got some problems with arduino nano, when dealing with bigger powers for led like 50W so that is why I used arduino Uno, it works fine. The problems was that it freezes (I think it was because the quality of power for 3.3V). In the lower powers like 10W there was no problems for arduino nano.
/**************************************************************** Title: MySensors enabled, gesture controlled lamp. V1.1 March 2016 by Theo This lamp can be turned on/off, and dimmed by gestures. And it can be controlled by any Home Automation system, that can talk with MySensors. Supported gesture: 1. Left to right stroke: turns lamp on 2. Right to left stroke: turns lamp off 3. Down to up stroke: increases brightness (When brightness is already at max, the lamp will blink - duration and blink count can be changed in the sketch) 4. Up to down stroke: decreases brgihtness (When brightness level is at 0 the lamp is off) The gesture sensor ues in this Sketch is an APDS-9960 RGB and Gesture Sensor, sold by SparkFun. They can be found on eBay and Aliexpress as well. See Sparkfuns hookup guide for pin lay-out ( https://learn.sparkfun.com/tutorials/apds-9960-rgb-and-gesture-sensor-hookup-guide ) IMPORTANT: The APDS-9960 can only accept 3.3V! Use bi direction level converter when using another Arduino than a Pro Mini 3.3V This Sketch is based upon the GestureTest exampl developped by, Shawn Hymel @ SparkFun Electronics on May 30, 2014. See https://github.com/sparkfun/APDS-9960_RGB_and_Gesture_Sensor The lamp itself is a white LED strip, controlled by an N channel MOSFET.

This was a little bug in previous version. It sometimes seemed that the APDS didn't work, but in some cases I had to increase brightness after I turned the lamp on. - cleaned up the code a bit 19-03-2016 Version 1.0 ****************************************************************/ // Import libraries used by the Sketch. // added some of my radio definitions (must be before #includes) #define MY_DEBUG #define MY_RADIO_NRF24 #define MY_RF24_PA_LEVEL RF24_PA_MAX #define MY_NODE_ID 10 // Enable repeater functionality for this node #define MY_REPEATER_FEATURE #include <SPI.h> #include <MySensors.h> #include <Wire.h> #include <SparkFun_APDS9960.h> #include <DHT.h> // Constants declaration(s) #define APDS9960_INT 2 // Needs to be an interrupt pin.

Got my gesture sensor from China today. Took a while to figure out that I had to solder the bridge for the ir led. Thanks a lot for the notes about setting gesture gain, I wasn't able to get gestures working until I found that note. The sensor works great now!

Got my gesture sensor from China today. Took a while to figure out that I had to solder the bridge for the ir led. Thanks a lot for the notes about setting gesture gain, I wasn't able to get gestures working until I found that note. The sensor works great now!

Hello. Can somebody publish working code just for gesture and LED dimming with latest mySensors library? Thank you.
@APL2017 Posting one question multiple times isn't gonna give you an answer quickly. I just wanted to say that.
I see the code on the website is still in pre MS 2.0. It should be easy to convert it to MS 2.0. The only problem is that I don't have the hardware setup to check if it works. If I can find some time this week I will convert it, so that it at least compiles. But I can not test it and can't promise I will finish it this week.
But @pjjarzembowski version should work, you should only strip out the extra sensors he attached to his node.
After playing with dimmers and Domoticz for quite some time, I've discovered that 15 brightness levels is all I need. Because it's hard to see the difference is brightness level if you have 100 levels. And also it takes a lot of gestures to move from max to min. So the code can be simplified more. By just mapping the Domotics level (1-100) to (1-15) and the opposite when you send the nodes brightness level to Domoticz.
Also Domoticz behaves odd when it comes to dimmer actuators as I discovered during a project I'm working on now. There are some work arounds for that, which envolve storing the brightness levels on the eeprom of your node. I know 100000 times is a lot. But I really don't see the need to store each brightness level change in the eeprom.

@TheoL Sorry, I though that I deleted multiple posts. I understand about stripping the code, this is what I am trying to do, just got a bit confused between parts of the code responsible for measuring and controlling the light (similar variable names, etc.). Thanks for the idea about reducing number of light levels, totally make sense. My personal take on this project would be having gesture controller physically separate from the light controller with mySensors node to node communication between. May I ask you why you don't use this setup anymore? FYI, I use ioBroker as controller and happy with it (most of the time)

@APL2017 I think the gesture sensor is awesome. But just to switch things on and off. Because dimming with hand gestures is fun at the beginning, but I discovered I didn't use it much after a few months. To me most of my projects are just experiments on finding usable ways to interact with my house.
But there are some good use cases in where a gesture controller is the best switch you can imagine. Because it is contactless. Like in your garage when you are working on stuff like cars and get your hands dirty. You don't want to make you wall switches dirty.
Or in your kitching while cooking. But dimming with gesture is not very convenient. So I would set a max dimmer level of 5 or so. -

@TheoL Please see attached stripped version of @pjjarzembowski code. I see that gesture is being detected, attempted to reduce number of light levels to 5. Having trouble with detecting UP and DOWN gestures - not always happening. Trying to understand how dimmer works.
/**************************************************************** Title: MySensors enabled, gesture controlled lamp. This lamp can be turned on/off, and dimmed by gestures. And it can be controlled by any Home Automation system, that can talk with MySensors. Supported gesture: 1. Left to right stroke: turns lamp on 2. Right to left stroke: turns lamp off 3. Down to up stroke: increases brightness (When brightness is already at max, the lamp will blink - duration and blink count can be changed in the sketch) 4. Up to down stroke: decreases brgihtness (When brightness level is at 0 the lamp is off) The gesture sensor used in this Sketch is an APDS-9960 RGB and Gesture Sensor, sold by SparkFun. They can be found on eBay and Aliexpress as well. See Sparkfuns hookup guide for pin lay-out ( https://learn.sparkfun.com/tutorials/apds-9960-rgb-and-gesture-sensor-hookup-guide ) IMPORTANT: The APDS-9960 can only accept 3.3V! Use bi direction level converter when using another Arduino than a Pro Mini 3.3V This Sketch is based upon the GestureTest exampl developped by, Shawn Hymel @ SparkFun Electronics on May 30, 2014. See https://github.com/sparkfun/APDS-9960_RGB_and_Gesture_Sensor The lamp itself is a white LED strip, controlled by an N channel MOSFET. Fore more details on the used hardware and libraries (see https://www.openhardware.io/view/50/Gesture-controlled-MySensors-Floor-lamp ) Revision history: 25-1-2021 Version 2.1 Stripped from everything except gesture and light control. 3-07-2017 Version 2 by pjjarzembowski - Changed for tests on Mysensors 2.0 20-03-2016 Version 1.1 by Theo: - set the brightness level to defined BRIGHTNESS_INCREMENT, when lamp is being turned on be a gesture and the current brightness level is 0. This was a little bug in previous version. It sometimes seemed that the APDS didn't work, but in some cases I had to increase brightness after I turned the lamp on. - cleaned up the code a bit 19-03-2016 Version 1.0 by Theo - Developed and test with MySensors release 1.5.4 ****************************************************************/ // Import libraries used by the Sketch. // added some of my radio definitions (must be before #includes) #define MY_DEBUG #define MY_RADIO_RF24 #define MY_NODE_ID 27 //#include <SPI.h> #include <MySensors.h> #include <Wire.h> #include <SparkFun_APDS9960.h> // Constants declaration(s) #define APDS9960_INT 2 // Needs to be an interrupt pin.

@TheoL Please see attached stripped version of @pjjarzembowski code. I see that gesture is being detected, attempted to reduce number of light levels to 5. Having trouble with detecting UP and DOWN gestures - not always happening. Trying to understand how dimmer works.
/**************************************************************** Title: MySensors enabled, gesture controlled lamp. This lamp can be turned on/off, and dimmed by gestures. And it can be controlled by any Home Automation system, that can talk with MySensors. Supported gesture: 1. Left to right stroke: turns lamp on 2. Right to left stroke: turns lamp off 3. Down to up stroke: increases brightness (When brightness is already at max, the lamp will blink - duration and blink count can be changed in the sketch) 4. Up to down stroke: decreases brgihtness (When brightness level is at 0 the lamp is off) The gesture sensor used in this Sketch is an APDS-9960 RGB and Gesture Sensor, sold by SparkFun. They can be found on eBay and Aliexpress as well. See Sparkfuns hookup guide for pin lay-out ( https://learn.sparkfun.com/tutorials/apds-9960-rgb-and-gesture-sensor-hookup-guide ) IMPORTANT: The APDS-9960 can only accept 3.3V! Use bi direction level converter when using another Arduino than a Pro Mini 3.3V This Sketch is based upon the GestureTest exampl developped by, Shawn Hymel @ SparkFun Electronics on May 30, 2014. See https://github.com/sparkfun/APDS-9960_RGB_and_Gesture_Sensor The lamp itself is a white LED strip, controlled by an N channel MOSFET.

This was a little bug in previous version. It sometimes seemed that the APDS didn't work, but in some cases I had to increase brightness after I turned the lamp on. - cleaned up the code a bit 19-03-2016 Version 1.0 by Theo - Developed and test with MySensors release 1.5.4 ****************************************************************/ // Import libraries used by the Sketch. // added some of my radio definitions (must be before #includes) #define MY_DEBUG #define MY_RADIO_RF24 #define MY_NODE_ID 27 //#include <SPI.h> #include <MySensors.h> #include <Wire.h> #include <SparkFun_APDS9960.h> // Constants declaration(s) #define APDS9960_INT 2 // Needs to be an interrupt pin.

@APL2017 I bought a real expensive one at the time from sparkfun. Maybe that's a difference, because it was stable. I think some where in the back of my drawer I have some cheap Chinese ones. But I'm in the middle of 3 other builds xd. So not sure if I can hook them up real soon. But great you solved a problem.
I think the one I used original has no built in 3.3v regulator. -

@TheoL I ordered just in case couple of simple APDS modules without regulators. When you have a chance, no rush, please take look at the code, thank you.
@APL2017 I converted the MySensors 1.5 version to 2.x. It compiles but I can not test it since I don't have a hardware setup.
Can you give it a try?

@APL2017 I converted the MySensors 1.5 version to 2.x. It compiles but I can not test it since I don't have a hardware setup.
Can you give it a try?
/**************************************************************** Title: MySensors enabled, gesture controlled lamp. V1.1 March 2016 by Theo v2.3 January 2021 by Theo (converted to MS 2.0) This lamp can be turned on/off, and dimmed by gestures. And it can be controlled by any Home Automation system, that can talk with MySensors. Supported gesture: 1. Left to right stroke: turns lamp on 2. Right to left stroke: turns lamp off 3. Down to up stroke: increases brightness (When brightness is already at max, the lamp will blink - duration and blink count can be changed in the sketch) 4. Up to down stroke: decreases brgihtness (When brightness level is at 0 the lamp is off) The gesture sensor ues in this Sketch is an APDS-9960 RGB and Gesture Sensor, sold by SparkFun. They can be found on eBay and Aliexpress as well. See Sparkfuns hookup guide for pin lay-out ( https://learn.sparkfun.com/tutorials/apds-9960-rgb-and-gesture-sensor-hookup-guide ) IMPORTANT: The APDS-9960 can only accept 3.3V! Use bi direction level converter when using another Arduino than a Pro Mini 3.3V This Sketch is based upon the GestureTest exampl developped by, Shawn Hymel @ SparkFun Electronics on May 30, 2014. See https://github.com/sparkfun/APDS-9960_RGB_and_Gesture_Sensor The lamp itself is a white LED strip, controlled by an N channel MOSFET. Fore more details on the used hardware and libraries (see https://www.openhardware.io/view/50/Gesture-controlled-MySensors-Floor-lamp ) Developed and test with MySensors release 1.5.4 Revision history: 31-02-2021 Version 2.2: - Sketch converted to MySensors 2.0+ (Not not tested) 20-03-2016 Version 1.1: - set the brightness level to defined BRIGHTNESS_INCREMENT, when lamp is being turned on be a gesture and the current brightness level is 0. This was a little bug in previous version. It sometimes seemed that the APDS didn't work, but in some cases I had to increase brightness after I turned the lamp on. - cleaned up the code a bit 19-03-2016 Version 1.0 ****************************************************************/ // Set the wait for ready to zero if you want the light the be operable even when the Gateway is off. //#define MY_TRANSPORT_WAIT_READY_MS 0 // Enable and select radio type attached #define MY_RADIO_NRF24 // Import libraries used by the Sketch. #include <SPI.h> #include <MySensors.h> #include <Wire.h> #include <SparkFun_APDS9960.h> // Constants declaration(s) #define APDS9960_INT 2 // Needs to be an interrupt pin.

@TheoL Thank you so much for your efforts! The code works, I need to try to make gesture recognition a bit for stable (will replace module and maybe try different library) as well as reduce number of light levels as you suggested.
@APL2017 I'm working on a small library that handles a lot of those dimming features. We can always integrate it later on. But first let's try to make the gesture sensor stable. Then we can update the code on the website as well @mfalkvidd ?
