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 ...

Sure, the physical build itself looks great, but it’s what [Michael] did with the firmware that impresses us the most. He’s using an Arduino Mega to drive the 7x7x7 cube and manages to squeeze out ...

A digital camera has an array of sensors that captures light reflected or transmitted onto it. This build is something closer to a reverse camera – a single sensor that makes images on a matrix of ...

Connector to add external battery to real-time clock (RTC) inside Renesas MCU (MCU RTC power pad held to 5V rail on Minima) Secondary (wireless) processor: 240MHz 3.3V dual core 32bit Espressif ...

The Arduino UNO R4 Minima comes equipped with the RA4M1 microprocessor from Renesas. Providing a power-packed performance and an array of extended capabilities, this robust microcontroller board is a ...

No goofy active shutter glasses, no headache-inducing parallax barrier screens, no optical trickery here. This is a pure 3D display -- unfortunately done at a resolution of just 8 x 8 x 8. It's a hand ...

Watching a good old-fashioned light show is always a treat. Whether it be a Christmas light show covering a house or an army of drones making patterns in the night sky. Here, however, we have a light ...
