Build a countdown clock to help teach toddlers how to visualize time.
Guide: https://learn.adafruit.com/toddler-timer
This project uses NeoPixel LEDs to represent blocks of time that can be setup to countdown any number of minutes.
It features an OLED display to show the time remaining and a rotary encoder to set up the intervals and to start and stop the countdown.
You can customize the blocks of time in the code and easily cycle between them with the rotary encoder.
We think it’s a unique way to show the passage of time with NeoPixel LEDs.
This uses the Adafruit QT PY RP2040 dev board to drive the NeoPixels and the rotary encoder.
CircuitPython makes it easy to change up the code so you can make adjustments or adapt to your roll your own countdown timer.
You can customize the code to have different blocks of time or change the colors of the NeoPixel LEDs.
