mCookie-Motor

mCookie-Motor is a DC motor controller with PWM(Pulse Width Modulation). The speed of the motor can be controlled through PWM and mCookie-Motor has to be powered with BM module.



Features

  • Current & speed limited by internal PWM
  • Synchronous rectification can reduce power consumption;
  • DC motor braking mode;
  • Capable of controlling two DC motors;

Specification

  • External power supply: BM module
  • Pin Description
mCookie pin Motor chip pin Function
D6 1A Control 1A high level and rotate clockwise
D8 1B Control 1B high level and rotate counter clockwise
D5 2A Control 2A high level and rotate clockwise
D7 2B Control 2A high level and rotate counter clockwise
VMOT BM module Power supply
GND GND Ground

Note: The pins including 5, 6, 7 and 8 cannot be occupied by other sensors while using the Motor or it may cause problems.

Development

DC Motor Wire Connection

  • Connect one DC motor to (OUT1A, OUT1B) and the other to (OUT2A, OUT2B);
  • DC motor pin control:
//(D6, D8) controls motor (1A, 1B) 
#define OUT1A 6
#define OUT1B 8
//(D5, D7) controls motor (2A, 2B) 
#define OUT2A 5
#define OUT2B 7

PWM Rate Control

    // Loop statement. Along with PWM rate decreases, you can change brightness level by controlling fadeValue.
  {
    digitalWrite(OUT1A, LOW);
