Good day all, my name is Ant and iv just joined the forum. Can someone help me select the the right board please. I want to operate 3 banks of LED Lights, Red, Amber and Green using a remotely operated push button controller. Preferably 12volt system. I have bought the Transmitter and receiver units. They are 4 separate buttons. I was thinking 1-Swith unit On, 2- Red, 3-Amber, 4-Green. Its for a rural Speedway circuit and we were thinking it would be cheaper to do it like this, rather than run 240volt cable 300meters, off a generator. Looking forward to some help, Ant.
I think you’re asking for something to turn the Rx signal into turning the lights on/off? You’d grab 3 each of these 3 items
Amazon.com: SparkFun Qwiic Single Relay-Up to 5.5A at 240VAC Multiple I2C addresses Available Turn on/Off high Power Device from Low Power microcontroller No Soldering Large Power Loads w/Simple I2C Commands : Electronics (we’re out of stock on our site currently)
and then wire the 12v LEDs to the output from the relay.
You’ll need to write code that accepts the Rx input on one of the Redboard’s pins (each) and then activates the qwiic relay Qwiic Single Relay Hookup Guide - SparkFun Learn to turn the LEDs on
