Control several motors with Motor Shield V2 and Arduino

Control several motors with Motor Shield V2 and Arduino

The Motor Shield V2 is an expansion board for microcontrollers Arduino UNO and Mega to control DC and stepper motors. For motor control, it is possible to use integrated circuits directly but their use requires significant wiring can quickly become unmanageable. To...
Improve your Arduino program

Improve your Arduino program

Memory space is limited on an Arduino board, it may be important to improve your Arduino program in order to avoid certain problems. The more we advance in programming, the more we come to write long and complex programs. It is important, as soon as possible, to take...
Control several motors with Motor Shield V1 and Arduino

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...
Management of a push button with Arduino

Management of a push button with Arduino

One of the most common examples when learning programming with Arduino is the management of a push button. Indeed, one of the most useful functions to develop is to be able to interact with the Arduino board. The most minimalist interface is a push button input and...
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...
