How to interact with a SD card from the ESP32, using the Arduino core.
How to obtain barometric pressure measurements from a BMP388 sensor, using the ESP32 and the Arduino core.
How to control a DC motor using an ESP32 and a PS4 controller
In this tutorial we will check how to control a DC motor using the micro:bit board and MicroPython.
Controlling a relay remotely via HTTP using the ESP32.
How to control a buzzer with PWM, using the ESP32 and the Arduino core.
The objective of this post is to explain how to use a 4×4 matrix keypad with the ESP8266. For simplicity, we will assume the use of the ESP8266 integrated in a NodeMCU board.
The objective of this post is to explain how to detect rain drops using the ESP8266, external interrupts and a rain sensor.
The objective of this post is to describe a cheap rain sensor that can be used to detect rain with microcontrollers such as the Arduino or the ESP8266.
