Give voice to your Arduino project
To make your Arduino project more interactive, it can be fun to make sounds based on certain actions. In this tutorial, we will see how to play a WAV audio file saved on an SD card with Arduino Prerequisite:Read and write on an SD card , Create or modify an audio file...
Using a LCD16x2 Screen with Arduino
One element that displays the most used in the world is information Arduino liquid crystal display (Liquid Crystal Display) LCD 16×2. When an electronic system is made, it may be interesting as it gives us some information about his condition without having to...
Using a distance sensor GP2Y0A21 with Arduino
The sensor GP2Y0A21 is an infrared distance sensor from Sharp that can detect object located at a distance between 10 and 80cm in front of it. Hardware Computer Arduino UNO USB A/B GP2Y0A21 Operating principle The distance sensor GP2Y0A21 uses infrared light to...
Program a NodeMCU ESP8266 with Arduino IDE
A large number of microcontrollers such as NodeMCU ESP8266 can be programmed with the Arduino IDE. Arduino boards are powerful and very practical for learning and carrying out projects, with an extremely large mutual aid community. However, there are other...
Using a RFID module with Arduino
The RFID module is a smart card reader which allows among others, to activate a mechanism when the correct card is presented to the reader. We will use here the RC522 module, which is the most common. Hardware Computer ArduinoUNO USB Cable Module RFID Dupont Cable M/F...
Using a Potentiometer with Arduino
The potentiometer is a variable resistor which is used to vary the voltage at its terminals. It is used in several applications including set a value: adjust the brightness of a light, adjust the volume of a speaker, change the position of a servomotor, etc. Hardware...
Luminosity measurement with a photoresistor
A photoresistor is an electronic component that measures ambient light. This component is useful in some projects such as a solar panel light follower or home automation to create a smart lamp that only turns on when it is dark or to set up an alarm with a laser...
Read and write on a SD card with Arduino
One of the weak spot of the Arduino is the memory space. When playing with data (saving measurement, reading or writing to a file, etc.), it is necessary to have lot of space available. You can easily add memory to the Arduino with a Secure Digital card or SD card....
Program your Raspberry Pi with C/C++
Ressources for Raspberry PI are generally written for Python but, as a micro computer, other languages can be used. If you know C/C++ ( If you come from the Arduino world, for instance) and don’t want to bother learning another computing language, it is possible...Products
