In exploring the use of analogWrite() and digitalWrite() on the Raspberry Pi Pico using Arduino, I have discovered some strange behaviors when switching between those modes on the same GPIO pin. This ...

I wanted to do something really simple. Having several LEDs controlled by PWM. Everything was working very weird with analogWrite so I tried several boards and reduced the setup to the minimal. It is ...

Perhaps one of the most common modules in an Arduino starter kit, the RGB LED lets you create all sorts of colors with just four pins from the Arduino. This tutorial demonstrates two ways to use this ...
