Halloween Lights

A little Halloween fun. I've added LED strip lights to an old Halloween plastic ghost and jack-o-lantern and automated switching them off/on using a MySensors node.

@NotYetRated Hope you'll find good uses and a fun time while building your sensors.

Quick Range Check on the WIO-E5-LE. The LE version uses only the low power PA, +14dBm max. Using the default settings except for 915MHz #define MY_SX126x_FREQUENCY (SX126x_915MHZ) #define MY_SX126x_LORA_SF LORA_SF7 #define MY_SX126x_LORA_BW LORA_BW_125 #define MY_SX126x_LORA_CR LORA_CR_4_5 I get about 190 meter range, just walking around the neighborhood, line of site except for some trees and power lines. No tuning on the antenna. Just using a 77.9mm wire. Not as dramatic as some have achieved with LoRa radio's, but plenty good enough for my house and yard : )

Hallo! Ich habe gerade meinen Aduino Nano mit einem GY-BME/P-280 verbunden über SPI verbunden. Im Sketch habe ich nur die PINS geändert und zwar auf: #define BMP_SCK 13 #define BMP_MISO 12 #define BMP_MOSI 11 #define BMP_CS 10 Ich bekomme aber bei der Ausgabe am seriellen Monitor nur "Hyroglyphen" zB 5��,�lh��}��'�O8��m�h,� Mit einem anderen Sketch funktioniert der Sensor einwandfrei. Auch mit einem anderen Nano dasselbe Ergebnis. Hat jemand eine Idee was das Problem sein könnte? Zusatzfrage da ich in C++ nicht so firm bin: Könnte es sein, dass MY_DEBUG oder MY_RADIO_NRF24 das problem verursacht. Was machen diese Definitionen eigentlich? Grüße

@OldSurferDude yes, you are correct. this sensor is capable of 50A continuous, which safely I would make it working at 40A max., but for such an important load as in your case I would go for a beefier one, like the ACS75x, 77x, but at this point I would also change the node's form factor for space and insulation reasons. On my application on the RV I have a max. curr. of 13A running on a AWG14-16 cable (European rules for RVs), so I did not ask myself too many questions beside, of course, safety. About the signal, it will be a sinusoidal signal swinging around Vcc/2. Vcc can be easily measured internally on the ATmega328. On all my DC sensors I measure Vcc at every loop, just before measuring the ADCs. Honestly, when the space is not an issue like in my RV, I would rather use a ring core current transformer, and I would get rid of noise, response time, power dissipation, but over all no need to cut any cable. Long story short, it has been a nice experiment and I used it for 6 months, and then I switched back to my RF-NANO based RS485-Modbus - Mysensors bridge connected to an off-the shelf power analyzer. Just for fun I attach a pic of my 12Vdc sensors installed on my RV. Forgive me for the spaghetti wiring on the right side, but this is an area that needs improvement.
