An Arduino Uno (CH340G clone) reads temperature and humidity from a DHT11 sensor and computes 10+ environmental metrics (heat index, dew point, enthalpy, humidex, vapor pressures, etc.), outputting ...

I missed this one before, when it was announced at Electronica: the Uno SPE Shield, created by Arduino and Microchip working together. It turns out, though, that it wasn't available back then. And it ...

Here is a design for a full-featured motor shield that will be able to power many simple to medium-complexity projects. 2 connections for 5V 'hobby' servos connected to the Arduino's high-resolution ...

Wiring configuration to meet the SPE standard. You’ll find rather detailed hardware documentation and instructions to get started with the Arduino UNO R4 WiFi, including wiring and termination ...
