Electromechanics

2010 Week 3 - Sensing - Exercise

PIR - passive infra-red sensor.

2009 Week 2 - Physical Computing - Exercises

Here are some exercises to get you started moving things with Arduino:

LDR - control a blinking LED with a light dependent resistor (LDR).

HBridge - used to reverse the polarity of a motor.

Servo - control an RC (Radio Control) servo with a potentiometer.

2009 Week 5 - Grab Bag - Exercises

Transistor - build a circuit that will protect your Arduino when using an inductive load.

Stepper - drive a stepper motor with an Adafruit Industries Motor Shield.

Stepper Motors


A stepper motor (or step motor) is a brushless, synchronous electric motor that can divide a full rotation into a large number of steps. The motor's position can be controlled precisely, without any feedback mechanism.

http://en.wikipedia.org/wiki/Stepper_motor


DC Motors



A DC motor is an electric motor that runs on direct current (DC) electricity.

http://en.wikipedia.org/wiki/Dc_motor

RC Servo Motors



RC servos are composed of an electric motor mechanically linked to a potentiometer. Pulse-width modulation (PWM) signals sent to the servo are translated into position commands by electronics inside the servo. When the servo is commanded to rotate, the motor is powered until the potentiometer reaches the value corresponding to the commanded position.

http://www.makingthings.com/documentation/how-to/stepper-motor - You want to connect a stepper motor to the Make Controller Kit with an Application Board.

http://www.imagesco.com/articles/picstepper/02.html - Stepper motors consist of a permanent magnet rotating shaft, called the rotor, and electromagnets on the stationary portion that surrounds the motor, called the stator.

Mechanisms

Mechanisms are used to convert between one type of motion and another. Any machine can be looked on as a group of interconnected mechanisms which convert one type of motion to a variety of other motions.
