hi everyone,
im working in project rc car avoids obstacles on way, im using arduino uno , lately purchased arduino mega 2560 try it, , using motor shield v3.0 control driving motor, car requires 7.2 v aprox 1800 mamps, im using battery thats coming power shield, , broke jumper pin between shield , micro controller board. shield supposed support 2 amp per terminal. when connect everything(with uploading simple code run motor ), shield leds motor seems stay on 10 seconds , starts break up. dc motor has 3 capacitors attached manufacture (one between terminals , 1 between each terminal , motor body).
ps: motor runs perfectly, tried using relay , , runs @ full speed.
void setup() {
//setup channel a
pinmode(12, output);
pinmode(9, output);
}
void loop(){
digitalwrite(12, high);
digitalwrite(9, low);
analogwrite(3, 255);
}

approx 1.8a motor shield without proper heatsinking...
