✨ Arduino and RGB 8x8 LED Matrix

In this project, the author will show how you can connect a full-color 8x8 LED matrix to the Arduino. The matrix itself has 32 inputs: 8 anodes, 8 red cathodes, 8 green and 8 blue. At the same time to control the matrix will be involved only 3 outputs on the Arduino. There is no magic here, but there are 4 shift registers 74HC595.

🌡 Temperature and humidity measurement on Arduino - a selection of methods

To create a home weather station or thermometer, you need to learn how to match the Arduino board and devices for measuring temperature and humidity. Temperature measurement can be managed with a thermistor or a DS18B20 digital sensor, but more sophisticated devices are used to measure humidity — the DHT11 or DHT22 sensors. In this article, we will explain how to measure temperature and humidity with the help of Arduino and these sensors.
