[Roni] programmed an Arduino Nano R4 to estimate Pi using the Monte Carlo method. For this specific case, it involves drawing a circle inscribed inside a square.

Here's an interesting way to control an Arduino using data-over-sound, demonstrated by Chirp. They show how to use their SDK to send an RGB value to change the colour of a on-board LED.

Arduino Maker Nano RP2040 “Slightly shorter than a Pico, this board has 30 pre-soldered pins, all helpfully labelled on the silkscreen.

Arduino has created a Renesas RA4M1 microcontroller board in its Nano form-factor. Called Nano R4, it follows the Uno R4, the first Arduino to use the RA4M1. “Whether you’re working on a connected ...

There are plenty of Arduino weather station tutorials available to follow but one published by Kutluhan Aktar not only displays whether information and activate RGB colour patterns but it also ...
