In this quick tutorial I’ll fix 2 dead ESP32 boards and also show how to use serial communications between a Raspberry Pi and an ESP32.

In this tutorial a LoBo MicroPython WebSocket server will broadcast temperature data from a DS18b20 sensor connected to an ESP32. A web page built with React and MobX State Tree on a Raspberry Pi will be the client.

This MicroPython tutorial demonstrates utilizing the ESP32’s built-in capacitive touch sensors. A simple music player is constructed utilizing a JQ6500 MP3 module connected to an ESP32 via serial communication. The touch interface provides feedback by using pulse width modulation to vary LED brightness.

This MicroPython tutorial demonstrates how to connect and drive a color SSD1351 OLED display using an ESP32. It also includes using the ADC to read analog signals and FTP for file transfers.

This tutorial demonstrates how to set up a MicroPython web server on an ESP32. A web page will show the temperature and humidity from a DHT22 sensor connected to an ESP32. Another web page will provide remote color and brightness control of a NeoPixel RGB LED.

This tutorial demonstrates how to connect a DHT22 temperature and humidity sensor to an ESP32 running MicroPython. The sensor data is transmitted wirelessly to a Raspberry Pi using MQTT protocol and the results are displayed on I²C OLED display.

This tutorial demonstrates how to set up and program an ESP32 device running MicroPython from a Raspberry Pi.
