@loralg do you have atmega168 or atmega328 Pro Minis? It should say in tiny print on the chip.

Sketch uses 18,642 bytes (130%) of program storage space. Maximum is 14,336 bytes.

Any suggestions on what I might be doing wrong? I am pretty new so I might be overlooking something really simple..

This will work for most situations I need. Is there an option to add the buttons and motion to one or more of the led's?

Hate to bother you again.

 * DESCRIPTION
 * This sketch provides a Dimmable LED Light using PWM and based Henrik Ekblad 
 * <henrik.ekblad@gmail.com> Vera Arduino Sensor project.  
 * Developed by Bruce Lacey, inspired by Hek's MySensor's example sketches.
 * 
 * The circuit uses a MOSFET for Pulse-Wave-Modulation to dim the attached LED or LED strip.  
 * The MOSFET Gate pin is connected to Arduino pin 3 (LED_PIN), the MOSFET Drain pin is connected
 * to the LED negative terminal and the MOSFET Source pin is connected to ground.  
 *
 * This sketch is extensible to support more than one MOSFET/PWM dimmer per circuit.
 *
 * REVISION HISTORY
 * Version 1.0 - February 15, 2014 - Bruce Lacey
 * Version 1.1 - August 13, 2014 - Converted to 1.4 (hek)
 * Version 1.2 - January 22, 2015 - Created a seperate control for the basement LEDs 
 * Version 1.3 - March 7, 2015 - Added coat closet LED

@petewill Yes that's what I'm talking about. Just wondering how the code was modified to discretely control the 3 zones.

you want with or without the buttons?

If with, how would the buttons work?

Sorry it has been too long since I made this video and I don't remember the reference. If you're talking about my Arduino that dims three separate lights it's basically just the same wiring except you use 3 different PWM pins to the 3 different MOSFETs. The max wattage is determined by the MOSFET you use.

If that's not what you're referring to, let me know.

Thanks,
Richard

I'm going to test this this weekend and see if I can make it work :)

Do you think One arduino can control both sides or do I need 2 different arduinos (+ electronics) and one won't be enough.

Definitely. I have one pro mini controlling 3 different dimmers. You just need to make sure you use PWM pins for the outputs.

I have a question on this project.

I'm replicating it for a wider mirror and I was thinking about having two separate dimming zones ( left and right ). based on the sketch and the design: Do you think One arduino can control both sides or do I need 2 different arduinos (+ electronics) and one won't be enough.

Happy to details more if needed.

thanks in advance!

I do need to work on the power video. There are so many things I want to work on I have been focusing on making videos as I work on new sensors. It's so hard to find time these days...

I'm building this for two mirrors as well as kitchen under counter and bookcase down lighting.

Your Vera videos have been MOST helpful. You do great "practical" work.

THANKS AGAIN!

Your videos are OUTSTANDING!

Thoughts?

What is your system setup? Thinking of doing the same.

I've built two of these for my daughters but instead of putting them behind a mirror I put it under their bed.

Scares away all the monsters? :trollface:
