This library is to use an HC4067 multiplexer by means of a PCF8574 (I2C 8 channel IO). The HC4067 allows e.g one analog port read up to 16 different analog channels, or one digital port to read the ...

With just an Arduino board, a DHT11 sensor, and an I2C LCD, you can create a simple yet effective weather station at home. This beginner-friendly project displays real-time temperature and humidity ...

Building Arduino projects with multiple sensors can unlock powerful environmental monitoring, automation, and IoT applications. From DHT11 temperature sensors to motion, gas, and light detectors, ...

You may not know what a ADM-3, a TV910, or a H1420 are, but you probably have at least heard of a VT-100. They are all ...
