In this guide, we will explore the DHTesp library, a powerful tool for interfacing with DHT temperature and humidity sensors in Arduino projects. The library works for Arduino, ESP8266 and ESP32.

You can use the DHT22 (or AM2302) humidity/temperature sensor and the Arduino UNO board to read data and print it out to the serial monitor or to display it on an LCD ...

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 WiFi — are all ...
