Motor Shield is commonly used for roboracing or controlling up to two independent motors of various sizes with a separate power supply. Designed in the summer of 2011 by theNelson at XinCheJian after holding a Eagle CAD workshop, these went for production and is commonly used on the monthly roborace, some uncommon uses also happen when a member wishes to control *something* with an independent power supply.

Usage examples

This is a simple Arduino to h-bridge power loopback to take the power from the Arduino

This was the original sockets before i got to burning it, notice the power in and the motor out's

Please note:

Sample Code

//h-bridge shield 
  int m1[] = {5,6};
  int m2[] = {9,10};

void setup() { 
  pinMode(m1[0], OUTPUT); 
  pinMode(m1[1], OUTPUT);
  pinMode(m2[0], OUTPUT); 
  pinMode(m2[1], OUTPUT);
}
void loop() {
  // motor 1 or m1
  //forward for 2 seconds 
  digitalWrite(m1[0],HIGH); 
  digitalWrite(m1[1],LOW); 
  delay(2000);
  //reverse for 2 seconds 
  digitalWrite(m1[0],LOW); 
  digitalWrite(m1[1],HIGH); 
  delay(2000);
  //do nothing for 2 seconds 
  digitalWrite(m1[0],LOW); 
  digitalWrite(m1[1],LOW); 
  delay(2000);
  //do nothing for 2 seconds 
  digitalWrite(m1[0],HIGH); 
  digitalWrite(m1[1],HIGH); 
  delay(2000);
  //motor 2 or m2
  //forward for 2 seconds 
  digitalWrite(m2[0],HIGH); 
  digitalWrite(m2[1],LOW); 
  delay(2000);
  //reverse for 2 seconds 
  digitalWrite(m2[0],LOW); 
  digitalWrite(m2[1],HIGH); 
  delay(2000);
  //do nothing for 2 seconds 
  digitalWrite(m2[0],LOW); 
  digitalWrite(m2[1],LOW); 
  delay(2000);
  //do nothing for 2 seconds 
  digitalWrite(m2[0],HIGH); 
  digitalWrite(m2[1],HIGH); 
  delay(2000);
