Generating Sounds with an Arduino MIDI Interface

In order to generate synthetic sounds on your computer using an interface and create music, it is possible to transform an Arduino into a MIDI device. Material ComputerArduino with USB port Introduction to the MIDI protocol MIDI (Musical Instrument Digital Interface)...
Using the PN532 RFID reader with Arduino

Using the PN532 RFID reader with Arduino

The NFC module PN532 is a smart card reader that, among other things, activates a mechanism when the correct card is presented to the reader. It can be found in smartphones, for example. The RC522 module is certainly the best known RFID module in the Arduino world,...
Force measurement with Arduino and the HX711 module

Force measurement with Arduino and the HX711 module

There are force transducers that are quite simple to use and compatible with microcontrollers such as Arduino. They consist of a load cell and a conversion module. The load cell is a strain gauge sensor that measures force in one direction in space. It is usually...
Generating and uploading HEX files to an Arduino

Generating and uploading HEX files to an Arduino

When you have a number of Arduino boards to flash with the same program, it can be interesting to flash the HEX compiled file directly. This has two interests. It saves you time on uploading and it allows third parties to upload a program without using the Arduino...
Using an AC Light Dimmer with Arduino

Using an AC Light Dimmer with Arduino

The AC light dimmer is a module that allows to vary the power of an alternating current. It has the same use as a transistor in direct current. It can be used to vary the brightness of a lamp supplied with 220V or to vary the speed of a fan, for example. Material...
