PWM (pulse width modulation and H Bridge, motors. (this might get changed to a motor shield)
Student Learning Outcomes :
- Student will learn how to pick a fuse for a simple circuit.
- Student will know how to calculate Watts from amps and volts.
- Student will learn to control simple DC motors including their speed and direction using an HBridge?.
- Student will learn to control Stepper Motors, and Hobby Servos.
- Student will learn about Pulse Width Modulation (PWM) Student will integrate motors into a project. Student will learn to consider types of movement as an aesthetic parameter.

- Relay control
- Transistor control of a motor
- Stepper Motors using tb6612 board from Adafruit https://learn.adafruit.com/adafruit-tb6612-h-bridge-dc-stepper-motor-driver-breakout/using-stepper-motors
- Servo Motors
Lectures, Demonstrations :
- H-Bridge wiring diagram. Ohms Law refresh, determining current, sizing fuses.
- Kirchhoff’s law applied to simple LED circuits.
- PWM - pulse width modulation for servos and and H Bridges. Apparent voltage for motors compensating for the HBridge? and PWM.
- Speed control
- Introduction to capacitance and inductance.
- flyback diodes
- H-Bridge See if you can figure out how to set up the H-Bridge and get it working with the helpsheets online, if you can't it is certainly OK to get help, but figuring it out yourself will provide a greater reward. The H-Bridge and two motors will be provided. Warnings and help will be given to prevent the board from burning out.
- Learn to control speed and direction of your DC motors. Demonstrate this in class
- Learn to use a hobby servo. Demonstrate this in class.
- Learn to use a stepper motor. Demonstrate this in class. Stepper motors will be available.
There is no project for H-Bridge, just the demonstrations. Turn in your code for all three exercises.
