CSCI 345: Lab 7

Motors
Due: 10PM on Monday, April 13th

In this lab, you should learn:

  • How to control different kinds of motors
  • How to teach yourself to use a new kind of input device

To complete this lab, you will need:

  • A computer.
  • An arduino.
  • A USB cable to connect your arduino to your computer.
  • A 6V motor
  • A PN2222 Transistor
  • A 1N4001 diode.
  • A servo motor.
  • A 10Ωk potentiometer.
  • 100 µF capacitor - OPTIONAL
  • L293D IC chip.
  • Button.
  • 5V Stepper motor.
  • A 270Ω resistor.
  • A breadboard.
  • Wires.

Part 0 - Github

Click here to create your github repo for this lab.

Part 1 - DC Motor

First, follow this guide to use control a DC motor with your arduino.

Part 2 - Servo Motor

Follow this guide to control a servo motor with your arduino.

Part 3 - DC Motor but backwards

Follow this tutorial to set up your DC motor so it can run both forwards and backwards.

Part 4 - Stepper Motor

Follow this tutorial to set up your DC motor so it can run both forwards and backwards.

Part 5 - Pick an input

Choose an input device that we have not yet used in a lab. Find a tutorial on how to use that input device, and follow the tutorial to set it up. Adafruit is a good place to look for tutorials, as is sparkfun and instructables. Your kit also came with a CD that contains guides for all of the parts it came with. Lastly, googling "arduino" and the name of your input device will probably turn up something.

Part 6 - Put it together and get creative

Take whatever input device you chose, and use it to control one of the motors. You may use any other output device that you wish for this project (LEDs, buzzer, etc).

Handin

You will submit your assignment by posting a comment on the piazza thread for lab 7. Your post should include a link to the a video of you demoing your program, and a link to a github repository that contains your arduino code.
