Arduino motor control

Arduino tip120 Motor: The current provided by Arduino nano digital pin is not sufficient to run a motor,
That is why we use the Tip120 transistor.

Parts Required:

1. Arduino Nano
2. Tip120 transistor
3. 1N4004 Diode
4. 9V Battery
5. Wire to connect it all together

TIP122 Transistor Pinout:

1N4004 Diod Pinout:

the 1n4004 Diod protect from reverse voltage and it’s a good idea to use it in our circuits.

1. connect all  Parts together

Arduino Code:

//Test Code

int Motor = 2; // the number of the Motor pin

void setup() {
//setup code:
pinMode (Motor,OUTPUT);
}

void loop() {
digitalWrite(Motor, HIGH);   // turn the Motor on
delay(1000);                       // wait for a second
digitalWrite(Motor, LOW);    // turn the Motor
delay(1000);
}
