In this tutorial we’re going to show you how to build a web server with the ESP32 that controls the shaft’s position of a servo motor using a slider. First, we’ll take a quick look on how to control a servo with the ESP32, and then we’ll build the web server. Watch the V...
After uploading the library to the ESP32 or ESP8266, copy the following code to the main.py file. It publishes the temperature and humidity on the esp/dht/temperature and esp/dht/humidity topics every 5 seconds.# Complete project details at https://RandomNerdTutorials.com/micropython-mqtt-...
This code might not have a practical application in the real world but is a great example to understand how to control the speed and direction of a DC motor with the ESP8266. /*** Rui Santos Complete project details at https://RandomNerdTutorials.com/esp8266-nodemcu-dc-motor-l298n-mo...
This tutorial shows how to use the DHT11 or DHT22 temperature and humidity sensors with the ESP32 and ESP8266 development boards using MicroPython firmware.
Learn how to display temperature and humidity readings from a DHT11/DHT22 sensor in an SSD1306 OLED display using an ESP32 or an ESP8266 with Arduino IDE.
