How to Use a Vibration Motor with Arduino (Lesson #25)

This video tutorial explains how to use vibration motors with Arduino. It covers the types of motors, such as ERM and pancake motors, and their applications. The tutorial details how to connect these motors to an Arduino using a breadboard and the importance of using transistors to power them. It also provides a simple Arduino code to control the motors with a button and discusses power supply considerations for different motor setups.

What is the primary function of a vibration motor in devices like cell phones?

• To create sound

• To produce vibration

• To drive a load

• To generate light

Which type of vibration motor is more compact and easier to mount?

• Wheel motor

• ERM motor

• Pancake or coin motor

• Propeller motor

What is a common issue when connecting vibration motors to a breadboard?

• The motors require too much voltage

• The breadboard holes are too small

• The wires are too thin and flexible

• The motors are too large

What tool can be used to secure connections between flexible leads and jumper wires?

• Wrench

• Hammer

• Needle nose pliers

• Screwdriver

Why is a transistor needed when using a vibration motor with Arduino?
