Connect a power supply, using a rectifier circuit.

Connection should include

• ripple
• regulation
• filter
• rectification
• reference point
• forward and reverse motor control (example, using an H-bridge)
• motor speed control.

A microcontroller should be connected to a motor using a semiconductor circuit, which controls the delivery of power to control the motion of the motor.

Note: In the case of stepper motors and solenoids, ripple controls motion and position.

Process/Skill Questions:

• What creates ripple effect?
• What is rectification?
• What is a common need for filter circuits?
