In this tutorial we will learn how to convert an image to grayscale using a Sipeed M1 based board. We are going to obtain the original image from a camera and display the resulting grayscale version in a LCD.Continue reading “Sipeed M1 MicroPython: Converting an image to grayscale”
In this tutorial we will check how to obtain an image from a camera and display it on a LCD, using a Sipeed M1 board and MicroPython.Continue reading “Sipeed M1 MicroPython: Displaying camera image in LCD”
In this tutorial we will learn how to control a DC motor remotely with the ESP32. We will be using the Arduino core and the HTTP async web server library. The tests shown on this tutorial were performed using an ESP32 board from DFRobot.Continue reading “ESP32 Arduino: Controlling a DC motor remotely using HTTP”
The objective of this post is to explain how to use the ESP8266 library defined constants that have the correct mapping between NodeMCU and ESP8266 pins.
The objective of this post is to explain how to get the body of a request sent to a HTTP webserver runing on the ESP8266.
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 scan the surrounding WiFi networks with the ESP8266.
