3D-Printed Visual Timer with LEDs, OLED Screen, and Rotary Encoder

Big thanks ‪@PCBWay‬ for sponsoring this video. Check out the manufacturing services offered by https://pcbway.com.

In this video, I take on the challenge of building a DIY visual timer for my toddler in 8 hours! Time can be a tough concept for kids to grasp, so I designed this 3D-printed timer with light tiles, an OLED screen, and a rotary encoder to make it easier for him to understand how much playtime is left. Whether you're a parent or a maker, this project is a fun way to combine creativity and functionality.
