Introduction

This motor shield allows Arduino to drive two channel DC motors. It uses a L293B chip which deliveries output current up to 1A (2A for L298P version) 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.

The Motor shield is powered directly from Arduino. It is strongly advised that use external power supply to power the Arduino instead of the USB power supply.

//This motor shield use Pin 6,5,7,4 to control the motor
// Simply connect your motors to M1+,M1-,M2+,M2-
// Upload the code to Arduino/Roboduino
// Through serial monitor, type 'a','s', 'w','d','x' to control the motor
