Neopixel + IR remote

huicholo · February 5, 2022, 1:15am

Hello guys, im trying to run a code in wich i can change the pattern in a Led ring, my problem is that while a pattern is running the arduino won´t recieve another command.

You can turn on interrupt 0 (pin 2) and use that to tell the sketch that an IR code is coming.

When the interrupt is acknowledged, you disable the pixel code section and wait for a repeat of the code.

i.e. You press a button on the remote, then you press the button a 2nd time to select the new animation you want.

BTW

In the Arduino IDE, use Ctrl T or CMD T to format your code then copy the complete sketch.

Use the </> icon from the ‘reply menu’ to attach the copied sketch.

What Arduino board are you using? On a board with 16-bit integers, you aren't going to fit that 24-bit code into 'value'.
