Sporting glowing headwear might be a little ostentatious for some of us, but the circuit in this project by itself is a neat point of departure for those who want to poke around at the EEG technology.

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Nevertheless, this could be a handy sensor, and it’s definitely a solid lesson in design. Still, if your tastes run more toward using this module on the 1.25-cm ham band, have a look at this ...

All of that sounds pretty good, right? Well, there’s still one more step: initial testing of the LoRa module(s). In addition to an Arduino Uno board, you’ll need a dedicated library developed for the ...

The UNO R4 WiFi version comes with an Espressif ESP32-S3 module for Wi-Fi and Bluetooth Low Energy connectivity. The bright 12×8 red LED matrix is ideal for creative projects using animations or for ...
