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.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
