HC-SR04 (ultrasound) vs Sharp GP2Y0A02YK0F (IR) vs VL53L0X (Laser), which solution to choose for distance measurement with Arduino or Raspberry Pi
We will compare the three proximity sensor technologies that make distance measurement possible. HC-SR04 by ultrasound, Sharp GP2Y0A02YK0F by infrared and VL53L0X by measurement of the flight time ...READ MORE +
The Sharp GP2Y0A02YK0F Proximity Proximity Sensor allows distance measurements between 20cm and 150cm. It is quite easy to get an Asian clone rated A02YK0 for less than €4. There are several Arduino ...READ MORE +
In the last article, we tested the 3.5 '' LCD touch screen for the Raspberry Pi 3. This small screen is very well suited for carrying out a portable retrogaming game console project. After testing ...
#Test LCD 3.5” HDMI touch screen (via GPIO) with acrylic case for Raspberry Pi 3 under Raspbian (480×320 to 1920×1080 pixels)
We are continuing our series of tests of different display solutions for the Raspberry Pi 3. Today, I propose to test the LCD 3.5 '' HDMI touch screen delivered with a clear acrylic case. The touch ...READ MORE +
#Guide: which ESP8266 module to choose, power supply, how to program it in C++ with Arduino IDE, MicroPython, ESP Easy
The ESP8266 was released in 2014. In just a few years it has gone from a simple WiFi module project for Arduino for a few euros to a full development board. The ESP8266 is a true Arduino Killer. It ...READ MORE +
If you regret having opted for the Lite version of Raspbian, here is a quick tutorial that explains how to manually install the Pixel desktop. No need to burn a new SD card for your Raspberry Pi.. ...READ MORE +
The Raspbian distribution supports the VNC remote desktop. It is very simple to set up and activate and does not require any technical skills to do it. The Raspberry Pi is an ideal platform for ...READ MORE +
Publish the CO2 concentration of an MH-Z19 sensor to Domoticz, Arduino code compatible ESP32 / ESP8266
In the previous tutorial, we discovered and tested the MH-Z19 sensor which allows to measure the CO2 concentration without calibration. We saw how to read the CO2 concentration returned on the sensor ...
Python library evdev on Raspberry Pi to use a Gamepad in your DIY projects (servomotor, games, robotic…)
The Python evdev library makes it possible to decode the codes sent by the input devices (keyboard, mouse, analog joystick, gamepad ...) to exploit them in any project. We can for example use a ...
ESP32 MicroPython project with several DS18B20 probes, publish the measurements to Domoticz using the HTTP JSON API
After several articles to present the principles of MicroPython on ESP8266 and ESP32 development board, it's time to get down to business. I propose to take the Arduino reading code of several Dallas ...
