DC Motor: Actuation Assignment 1
This is a simple stroboscope using a speed-controlled DC motor and a LED which blinks with a relatively high and adjustable frequency. The basic idea is to adjust the blinking frequency and/or the speed of the disk in order to obtain interesting patterns. For example, one can make the rotating disk look still, or slowly turn backwards/forwards. Technically, one potentiometer adjusts the motor speed and the other potentiometer adjusts the blinking frequency.

Material
Paper ( an image printed on one side)
metal brads
e flute board
dc motor
potentiometer
Code
The objective that I chose for myself for this assignment was to do the assignment without using the Arduino. As I discussed in the class, I thought it would be possible and it was. Though it is not as sensitive to the potentiometer as it would be when using an Arduino but it was cool but easy to redesign the circuit.
The components used:
1. DC Motor
2. Potentiometer
3. Battery
4. Zener Diode
5. Transistor
6. Copper Wire for completing connections
Description
A cardboard fan changes speed based on the speed of the wind outside. Wind data gathered by a python program calling a Weatherbug station via a JSON API and passed to the Arduino over serial. Use a potentiometer to scale the speed of the fan, so you don't have to keep recalibrating the code.

Description
For this project I used the DC motor and used balsa wood and a brass fastner to make the motor vibrate.

For this assignment I used the DC Motor to spin the paper propellers of a paper plane!
Components:
DC Motor, Potentiometer, Poster board, duct tape, Wires, Arduino Board, etc.
Code:
I used the same example text as on the assignment page
