Arduino Motor Shield
(SKU: DRI0001)
Introduction
This motor shield allows Arduino to drive two channel DC motors. It uses a L293B chip which
deliveries output current up to 1A each channel. The speed control is achieved through
conventional PWM which can be obtained from Arduino’s PWM output Pin 5 and 6. The
enable/disable function of the motor control is signalled by Arduino Digital Pin 4 and 7.
Roboduino Motor Shield uses PWM output Pin 6 and 9 and Digital Pin 7 and 8.
