Week 8: Segment 1: Servo Motors and Analog Inputs with the Arduino

This segment focuses on the use of servo motors with the Arduino.  

Goals:

• Understand servo motors and analog inputs.

In-Class Project:

• Write a library for potentiometers.
• Combine the servo with the proximity sensor. Use the proximity sensor library developed earlier.

Materials for this segment:

• Read the Arduino.cc page on the servo library.
  
• Watch the video on the right.
  
• Check out the data sheet for the SG-90 servo from the kit. (Note the 4.8 V operating voltage on their scant 'data sheet' - we fried one of these servos by running them from a lab supply with 5.0 V. It may be that the servo was defective - we did not repeat the experiment - be careful and ramp the voltage up slowly if you use an external supply!)
• Arduino sketch featured in the In-Class Project (see below the video on the right)
