I'm taking the liberty of starting a new thread for Arduino projects, as I couldn't find one dedicated to this, and figure that there may be a few people around here who do this sort of thing. If ...

T he ESP32 is a fantastic little microcontroller with a world of possibilities. Its specifications may appear modest, but its capabilities enable it to power all kinds of devices.

(D6 of Arduino connected to Din of WS2812B) It is highly recommended to connect a 100nF capacitor across the ‚5v and Gnd‛ connection, and a 100-470 Ohm resistor in series with the ‚Din‛ line of the ...

Use Arduino to handle sensor input and relay control. Pi runs a Python Flask server with a simple UI to toggle GPIO pins via serial commands sent to the Arduino. Use cron jobs on Linux to schedule ...

Code commonly flows downstream, from an open-source project into an organization’s own products. Upstreaming is the process of reversing that flow—contributing code back to an open-source project.

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 ...
