• To keep the input low when the button is not pressed

• To decrease current

• To provide power to the button

What type of transistor is commonly used to control a motor with an Arduino?

• NPN transistor

• PNP transistor

• N-channel MOSFET

• P-channel MOSFET

In the motor control code, what command is used to read the state of a button?

• analogWrite
