I've correctly wired up an Arduino Nano 33 BLE to a 4-channel AC dimmer from RobotDyn and noticed that the output signal produced by calling digitalWrite(D6, HIGH) is oscillating which results in the ...

A 3-D LED LED cube game that will be able to astound you with the combinations it is capable of. Inexpensive and easy to make, thanks to an Arduino.

Use any digital output pin on any digitalWrite() Arduino function compatible board to generate basic sounds and music notes with customizable tempo and pitch. No need for any extra libraries.

If you aren’t familiar, the digitalWrite () function is one of the key functions Arduino gives you to operate its boards– specify the pin and the value (high or low) to drive it.
