 Tutorial: Control a motor using the PNP transistor

 The function of this sketch is to control a DC motor using the Arduino with the help of the PNP transistor.
 The motor will be switched on for one second, then turned off, and the process will be repeated.

 Connections from the PNP transistor:
 • PNP emitter pin → Motor first wire
 • PNP base pin (middle pin) → Arduino pin 3
 • PNP collector pin → Arduino GND pin

 Connections from the motor:
 • Motor first wire → PNP collector pin
 • Motor second wire → Arduino VCC pin (5V)

*/
//The PNP base is connected to pin 3
#define Base 3

//Commands inside void setup run once
void setup() {
 //Base is defined as an output
 pinMode(Base, OUTPUT);
}

//Commands inside void loop run forever
void loop() {
 //Turn the motor on
 digitalWrite(Base, HIGH);
 //wait for a second
 delay(1000);
 //Turn the motor off
 digitalWrite(Base, LOW);
 //wait for a second
 delay(1000);
}
