Topic: Controlling 7x4 LEDs  (Read 141 times) previous topic - next topic


Was starting this project to light a grid of 7x4 up. I wanted to make all of them apart from 1 light up red and the other one to light up green, (Ideally the green one could change depending on the time of alarm) This would then be linked to an alarm so when the alarm goes off then they start to light up. I haven't got much of a clue about this haha but was hoping for some help or guidance.



Are these single colour leds with different colours in different positions, or rgb leds that can display many colours?

If they are rgb leds, I suggest using ws2812b leds.
