Programming a Teensy board with Teensyduino

Programming a Teensy board with Teensyduino

In this tutorial, we will see how to program a Teensy board with Teensyduino and the Arduino IDE. Teensy microcontrollers are development boards with an ARM architecture. They have a high computing power, a large number of inputs and outputs and communication...
Using an Arduino CNC Shield V3

Using an Arduino CNC Shield V3

In this tutorial we will see the use of the CNC Shield V3 for Arduino. To be able to manage a machine like a CNC or a 3D printer with several stepper motors, it is interesting to have a board that facilitates the connection of the different elements of the machine....
Program an ESP32 with MicroPython

Program an ESP32 with MicroPython

, , We have seen that the ESP32 NodeMCU is easily programmable using the Arduino IDE. We will see how to program it with MicroPython. The advantage of using Python to program an ESP32 is to use it to its full potential. Before following this tutorial, you must first...
Some Linux terminal commands

Some Linux terminal commands

In this tutorial, we will look at some essential Linux commands for using a Linux machine and a Raspberry Pi in particular. Machine information uname allows you to obtain system information (kernel name, kernel version, OS, etc.) pi@raspberrypi:~ $ uname Linux...
Multitasking program with ESP32 and FreeRTOS

Multitasking program with ESP32 and FreeRTOS

, The NodeMCU ESP32 is based on the Xtensa 32-bit LX6 dual-core microprocessor that embeds the FreeRTOS OS. When using the Arduino IDE, the program runs by default on core 1. To multitask, it is interesting to use all the resources of the microprocessor. In this...

Using a transistor module with Arduino

Using a transistor module with Arduino

The transistor module is composed of an electronic component, which can be seen as a controllable switch, which lets pass a current proportional to the voltage at its terminals when it exceeds a certain threshold. It allows, with a very low power signal, to supply a...
Send a mail from a Python script

Send a mail from a Python script

One of the main interests of programming languages, like Python, is to automate tasks like sending mail. In this tutorial we will see how to write a Python program to send an email from a Gmail account. This tutorial can be applied to any computer including a...
Using a Reed Switch (ILS) with Arduino

Using a Reed Switch (ILS) with Arduino

A reed switch or ILS is a magnetic sensor that detects the presence of a magnetic field. This switch will be activated by approaching a magnet. It can be used to know if a door is closed or open or to detect the presence of an object. Material Computer Arduino UNO USB...
Using a HC-12 module with Arduino

Using a HC-12 module with Arduino

Le module HC-12 permet la communication sans-fil semi-duplex entre deux appareils via les fréquences radio. Il travaille sur la mêmes plages de fréquences que le module RF433 mais permet d’atteindre des distances de communication beaucoup plus importante (<1km). De...
