Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

The clock’s digits are made from two LED matrices driven by an Arduino Uno and a couple of MAX7219 driver boards. The dots that form the digits move up and down the matrices in 1-3-4-2 firing order.

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

Here is a simple Arduino Camping Light project. In this design, only one push button switch is used to control the light output (from a bunch of white LEDs) between off, dim, medium, and full ...

The Arduino UNO R4 Minima and the Arduino UNO R4 WiFi. But apart from the obvious wireless connectivity hinted by the name what other differences do the microcontrollers have.

Having trawled though Arduino’s just-released Uno R4 literature, here are the Uno R4 WiFi and R4 Minima in a nutshell: Features common to Arduino R4 – ‘WiFi’ (€25, below) and ‘Minima’ (€18, right) IO ...
