I bought a very cheap RGB LED string with a remote control. The string connects with a USB-A to a 5 V power source. The connector has one push button and obviously also the IR receiver. Using a phone app I can do stuff with the string, which reveals that the leds are individually adressable. The phone app settings also reveals that the type of IC on the leds is ASL14040. But google can't find anything on ASL14040, except one page in Chinese, which shows that it indeed is some type of IC RGB LED. Any suggestions how I could program the string using an Arduino? I'm going to try to recognise the VIN, GND and perhaps SCL and SDA and try different libraries, but I thought someone might now something about this.
Verify what type of string you have. It's probably easiest to remove the original controller and connect the string to arduino. Another option is IR receiver to record the commands and transmitter to command through arduino.
I would put a scope on it and have a look at the waveform, but obviously that depends on having a scope.
Without a data sheet or any other info, I don't know how else to go, apart from try a WS2812 library and see if that works.
