We’re great fans of the MrHobbyelectronics’ YouTube channel, and in the latest update they show us how easy it is to use the Freetronics HBRIDGE Motor shield for Arduino by demonstrating a neat Arduino-based tank robot.
With the addition of an ultrasonic distance sensor to avoid collisions, and an infra-red sensor at the front bumper to detect a line – the robot can follow lines and also avoid objects in the way. You can see this in action through the following video:
Based around the powerful Allegro A4954 H-bridge driver IC you can control two DC motors with complete ease, or one bipolar stepper motor. With connections for external power management, a complete beginners’ guide and documentation – motor control couldn’t be any easier.
