The ESP32 AC MotorShield is an extension board that allows an ESP32 NodeMCU to drive two DC motors or one stepper motor. We've seen how to drive a DC motor using an H-bridge, which can require a lot of wiring when using a simple IC. For an embedded application, such...
We're going to take a look at how to program an ESP32 or ESP8266 board in MicroPython using Visual Studio Code, an IDE increasingly used for programming in a variety of languages. The ESP32 board can be programmed as follows Introducing Visual Studio Code Visual...
We're going to look at how to program an Arduino board using Visual Studio Code, a nice alternative to the Arduino IDE. Programming on the Arduino is generally started using the official IDE. It can be interesting to change code editors to gain access to a wider range...
To give your Windows PC a second lease of life, it may be enough to install Linux (Ubuntu or Debian) to keep the use of your computer. One of the main reasons for changing computers is loss of speed. Sometimes, when you upgrade your OS, hardware and software become...
, The OpenCV library is used for image processing, in particular shape and color recognition. The library has acquisition functions and image processing algorithms that make image recognition fairly straightforward, without the need for artificial intelligence. This...
In this tutorial, we'll look at how to set up a network of several ESP32s using the ESP-NOW protocol. The ESP32 is a Wifi-enabled development board. It can therefore connect and exchange data with devices connected to the same network. Hardware Computer NodeMCU ESP32...
In this tutorial, we'll look at how to configure two ESP32s to establish communication using the ESP-NOW protocol. The ESP32 is a development board integrating Bluetooth and WiFi. It can therefore connect and exchange data with devices connected to the same network....
In this tutorial, we'll show you how to drive a bipolar stepper motor using a DRV8825 driver. This tutorial is compatible with stepper motor drivers commonly used in digital milling or 3D printer projects (DRV8825, SilentStepStick, etc.). Hardware Arduino UNO Stepper...
In this tutorial, we'll show you how to drive a bipolar stepper motor using an A4988 driver. This tutorial is compatible with stepper motor drivers commonly used in digital milling or 3D printer projects (DRV8825, SilentStepStick, etc.). Hardware Arduino UNO Stepper...
In electronics, when working with electrical signals such as sensor measurements or audio signals, it is common practice to use filters. These filters are used to modify these signals with a view to correcting, analyzing or evaluating them correctly. This is known as...
