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

===DC Motor Wire Connection===
*Connect one DC motor to (OUT1A, OUT1B) and the other to (OUT2A, OUT2B); 
*DC motor pin control: 
<source lang="cpp">
//(D6, D8) controls motor (1A, 1B) 
#define OUT1A 6
#define OUT1B 8
//(D5, D7) controls motor (2A, 2B) 
#define OUT2A 5
#define OUT2B 7
</source>
