Arduino and Bluetooth module HC-06

Arduino and Bluetooth module HC-06

Arduino can communicate with other device via Bluetooth using the module HC-06 (slave).  It enables the Arduino to be connected and exchange data with other devices such as Smartphone, computer or other microcontrollers. Bluetooth communication can be used to...
Control a stepper motor with Arduino

Control a stepper motor with Arduino

One of the main objectives in robotics is to make things move on their own. To give motion to a robot, electrical motors are used such as stepper motors especially when precision is required with an open-loop control. In this tutorial, we study the use of integrated...
