After adding a Switch and an H-bridge, we can control the direction of motor’s spin.
// On this part, we add a switch and an H-bridge to the circuit. the H-bridge allows the changing of current flow. In the end, we can controll the direction of motor's spin.

Servo and Potentiometer
Add a servo and potentiometer to the circuit, and upload following code to the board.
#include <Servo.h>
Servo myservo; // create servo object to control a servo
int potpin = 0; // analog pin used to connect the potentiometer int val; // variable to read the value from the analog pin
void setup() { myservo.attach(9); //...
