DC Motor: Actuation Assignment 1

I used a DC motor and Potentiometer to create a prize roulette. User can use the potentiometer to adjust the speed of the rotation, and a color ball (which represent a specific prize) will randomly drop during the roulette rotation.

Component Used:

1 - Arduino Uno Board

1 - Potentiometer

1 - 1k Resistor 

1 - Breadboard

1 - DC Motor

2 - AA Battery 

1 - 1N4004

1 - TIP 120

1 - Paper Roulette

Several paper balls

This is an attempt to create a motor/blade combo to generate enough lift to be able to lift the motor and the bade off the table. The speed of the rotation and amount of lift are generated by a potentiometer. 

I carved a propeller blade out of a block of wood. I believed the blades to be long enough to lift the motor.

Unfortunately, the motor/battery 3-volt combo did not provide enough power to generate sufficient lift. It moved a lot of air but did not move off the table. I then used a more powerful battery that provided 4.8 volts, and it still was not sufficient.

Added a propeller and motor to my toy plane! Very simple but tons of fun. Very simple.

Materials

• -cardboard plane (cardboard, hot glue, wooden stick, duct tape)
• -motor
• -Balsa wood propeller
• -Arduino uno
• -transistor
• -2 AA batteries and holder
• -1 10k potentiometer

Description

For this assignment I build a mini blender using the DC Motor and a toy from Daiso. I disassembled the toy and replaced its content with the DC Motor. By the input from the potentiometer the DC Motor / blender output turns from minimum to maximum speed, and can plus be turned off.

The DC Mixer mixes your drinks. You can control the speed of the mixing on the knob on the side of the mixer. However, as it is right now, the mixer will throw your drink out the cup, so it still needs a bit of work when it comes to vibrations.

After finishing your business in a toilet, you will need toilet paper. :) If you are as lazy as you don't want to pull toilet paper, you will definitely need it. When you approach with your hand to toilet paper, this toilet paper dispenser will roll automatically so that all you need to do is just cutting the paper. After rolling the paper, it will make sound of success and turn on LED lamps.

Description

In this lab, a car that runs away when you try to touch it was created it. When you reach out your hand to try and catch the car from behind, it will zoom off until it reaches a safe distance away from you.

My intention was to make an automated bubble blower, attaching a fan to the motor and having the fan blow out the bubbles. The fan would have been controlled with a pot, using the sample code given during last week's lab.

Description:

For this lab, I created a miniaturized carnival ride by mounting a paper plate and cup on top of a piece of cork used to secure the ride to the motor.  A finger puppet of Sigmund Freud (only thing I could find that wasn't too heavy for the motor) sits in the cup and enjoys the ride--while, presumably, analyzing its subconscious motivation for spinning him around.  Mounting the cork slightly off-center on the motor allows the plate to spin wildly without losing its equilibrium--in true (I hope) carnival fashion.
