S4A Doodle Bot HD

DAGU now have a new version of the Mini Driver PCB that uses the ATmega328P and is compatible with Scratch for Arduino (S4A). In this video I demonstrate the Doodle Bot robot kit being controlled using S4A and a Bluetooth module. The Mini Driver MkII is a great little PCB for the classroom. It is low cost and has a dual FET motor controller built in rated for 2.5A per motor. Reverse polarity protection and a battery monitor are also built in. 3 pin servo headers on the I/O pins make it easy to power servos and sensors. Servos can be powered from the 5V regulator or directly from the battery.
