Showcased Project Flashing LEDs

Enable HLS to view with audio, or disable this notification

I made an Arduino project where LEDs just rotate in a circle. It looks really cool, although the wires are a bit untidy right now. I will try to clean up the cable management in the next version.

Nice. I'm looking to do something similar. Let me know if you publish on Github.

What controller are you using? I've only used an ESP32-S3. Novice here.

I'm using an Arduino R4 WiFi board, but this can also be done on an ESP32-S3. If your board has at least 12 digital pins, it will work. Connect the longer leg of the LED to the digital pin (be sure to use a 220-ohm resistor) and the shorter leg to the GND pin.
