Exercise 6: Motors and Mechanical Movement

Filed under: Assignments — mdgross @ 10:40 am

Mechanisms, Motors, and Movement
(show in class on Tuesday October 23)

Make something move. Build a moving mechanism that employs a DC, servo motor, or stepping motor, controlled by the Arduino.  Use sensors if you like to trigger, control, or otherwise mediate the motion.  Use a power transistor (as shown in class) to control the power supply to the motor or other external device (e.g. fan, pump, lighting).

This exercise has two purposes.  First, learn to control something with an external (that is, not on the Arduino) power supply.  That is because there isn’t enough power on board the Arduino to do very much.  Second, continuing last week’s exercise on mechanical motion, connect the motion to computer control.  You may construct your own mechanism, use the mechanism you built last week, or adapt an existing mechanism (swivel chair, luxo-lamp, etc.)
