DC Motor: Actuation Assignment 1

In this assignment, I decided to make a pinwheel fan using a DC motor. You can also use the potentiometer to control the speed of the fan. 
 
Components
1 DC Motor
1 Arduino Board
1 Bread Board
1 Potentiometer
1 Diode
1 Transistor
1 Battery
Connecting Wires
Code: I used the same code provided in the DC Motor assignment page.

For this assignment, i used a dc motor to roll a tissue paper roll automatically. I tried using the cardboard cylindrical thing that comes with the tissue paper, but since the circumferece was too big, it didnt really work. So finally i used a pencil as a holder and glued one end of the tissue paper rool to the pencil and then stuck the pencil to the motor.
 
Materials used:
1 arduino
1 breadboard
1 dc motor
1 pencil
1 small roll of tissues
1 laptop
1 battery to power the motor
 

Description:
In this project I was interested on what sort of sparkly things we could make with the DC motor.  If we put some tinsel on the motor, it creates a cool disco-effect. 
Materials:

Essentially this system measures the intensity and passion of a high five.  The glove is retrofitted with an FSR, the body of the motor has been secured to a tripod stand and its rotating arm to a slinky.  The analogInput from the FSR decides the time and speed of the motor.

Description
I explored eccentric weight placements by inserting the motor off-center in a circular piece of cork, attaching lengthy objects (such as a pen) off-center to the shaft, and others. I noticed that, despite the low-torque of the motor, it provides fairly substantial resistance while holding it as it spins at full speed. Add a big enough eccentric weight (that the motor could still spin) and you might have a low-powered grip trainer!

After completing the activity using the DC motor and potentiometer, I got the idea of making massage machine with the DC motor and the force sensor. The massage machine vibrates when I put pressure on the vibrating surface. The extent of vibration depends on how strongly I push the machine to body.

Disclaimer-- There is an issue with my DC Motor because it does not respond to analogWrite correctly. It only starts to function after I've gotten to the 500 threshold out of 1200. This is something that I did not expect with this project, so I would like to request a new DC Motor when I get to class.
 

Description:

After a lot of trial and error, I finally was able to succesfully demonstrate a kind of brownian motion using the dc motor. At the outset it seemed pretty easy to implement, using strong magnets on the motor and a set of etallic bearings placed in a container at some distance from the rotating magnets to influence motion. But as I started implementing it, it became quite complex. The system was delicate and everything depended on getting that perfect balance.

I have attached a link to the video. 

Description:
For this homework I thought to attach the DC Motor to a small plant and have the pot adjusted so that it moves very slowly. When plants grow, they tend to grow crooked since they grow where there's more sun. The purpose of this plant rotator would so that the plant will grow evenly and straight so that all sides of the plant have equal sun exposure. 

Description:
In this project, I used a DC motor to launch plastic balls. It is in the shape of a round tower with flower decoration. The launcher can be activated using a force sensing resistor, and the speed of the launch can be set using a potentiometer.
Thus, this project took the "Output" assignment very seriously :)
