This is a 100 second countdown timer which I filmed myself with my Canon EOS 100D camera. I used programable WS2812b LED stripe from a AMD cpu cooler. I connected it to Arduino and programed the software so that the LEDs light up in green, yellow and red colour. The numbers are seven segment LED displays which I am cotrolling also with Arduino and I've written the code also. Hope you like!
