As I've experimented and played with a lot of different sensors, I've discovered that these basic devices can be built for super cheap, and they're incredibly versatile. When you're done using an ...

Versions The higher-end R4 WiFi version comes with an Espressif ESP32-S3 module for Wi-Fi and Bluetooth LE connectivity, and a 12×8 red LED matrix is present for basic animations or for plotting ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

Two new variants of the Arduino Uno development board, the lightweight Uno R4 Minima and the full-fledged Uno R4 WiFi, are each powered by a 32-bit microcontroller. These next-generation Uno boards ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

In case you missed it, the big news is that a minimal Arduino core is up and working on the ESP32. There’s still lots left to do, but the core functionality — GPIO, UART, SPI, I2C, and … ...

As much as we love the Arduino Uno, it's not the most powerful of hobbyist microcontrollers. Fortunately, the folks in Turin have just put the finishing touches on a 32-bit upgrade with buckets of ...
