Make a Sticky-Note Fan with Arduino

Students control small electric motors with Arduino microcontrollers to make simple sticky-note spinning fans and then explore other variations of basic motor systems. Through this exercise, students create circuits that include transistors acting as switches. They alter and experiment with given basic motor code, learning about the Arduino analogWrite command and pulse width modulation (PWM). Students learn the motor system nuances that enable them to create their own motor-controlled projects. They are challenged to make their motor systems respond to temperature or light, to control speed with knob or soft potentiometers, and/or make their motors go in reverse (using a motor driver shield or an H-bridge). Electric motors are used extensively in industrial and consumer products and the fundamental principles that students learn can be applied to motors of all shapes and sizes.
