 Please improve upon it! Let me know how you've made it better.
 
 This is really simple example code to get you some basic
 functionality with the MonsterMoto Shield. The MonsterMote uses
 two VNH2SP30 high-current full-bridge motor drivers.
 
 Use the motorGo(uint8_t motor, uint8_t direct, uint8_t pwm) 
 function to get motors going in either CW, CCW, BRAKEVCC, or 
 BRAKEGND. Use motorOff(int motor) to turn a specific motor off.
 
 The motor variable in each function should be either a 0 or a 1.
 pwm in the motorGo function should be a value between 0 and 255.

 direct: Should be between 0 and 3, with the following result
 0: Brake to VCC
 1: Clockwise
 2: CounterClockwise
 3: Brake to GND

سلام. برای درایو موتور dc استغاده کردم. 13ولت 2آمپر. اما آیسی و برد زیریش خیلی داغ میکنه. !!!
کسی به این مشکل برنخورده
