Timer - Work in Progress
The Goal of this project : use a neopixel ring or strip as a timer countdown.
The goal of this project : be able to show a minut or an hour going throug leds from a neopixel ring or a neopixel strip of 30 leds for example.
For a 30 leds neopixel strip, you can choose for example a 60 seconds coutdown : each led will go on one after one each 2 seconds. In the first third of the time, the strip will be green, then orange and red to finish.
You can change or re-code the time to make it faster or longer.
3 buttons and a 7 segment display allowallow you to adjust the time and launch the countdown.
