Task 2: Use a potentiometer to make the solenoid move up and down at different internals

• Use a digital pin and a transistor to power the solenoid.
• Use an analog input pin to read the potentiometer and control the delay..
• You can use the delay function (just in the blinking led example in the Arduino IDE) or the millis() function.
