Control several motors with Motor Shield V1 and Arduino

The Motor Shield V1 is an expansion board for Arduino UNO and Mega microcontrollers for DC and stepper motor control. We have seen how to control a DC motor using H bridge which may require a lot of connections when using the simple integrated circuit. In an embedded...
Manage multiple Arduino with an I2C bus

Manage multiple Arduino with an I2C bus

It can be practical, especially in home automation projects, to communicate between several devices. One of the commonly used techniques is the I2C (or TWI) protocol. The I2C protocol is a method which makes it possible to connect several “Master” cards and several...
