ArrBot Class 2 Notes

Today's class will consist of of setting up your Arduino environment, testing the Arduinos we made last time, and making "continous rotation" servos.


  • Soldering stuff
  • Laptop computer, if you have it
  • USB "Micro B" cable to fit your Arduino
  • Tiny #000 Phillips screwdriver (fits tiny servo screws), if you have one.
  • Small tweezers, if you have them.
  • Bring extra tools if you have them and don't mind sharing.

Installing Arduino Software
  • On your laptop, install the Arduino IDE 1.0.5.
  • Install the Arduino Addon Files.
  • Do this before class if you can.  If you need help, no problem.
  • If you don't have a laptop, no problem... we should be able to share.
Testing the Arduino Units

  • (need to verify which test programs are good)
  • Connecting via Serial Monitor

Set Up the Servo Tester

Make the Continuous Rotation Servos

  • see video tutorial and notes on Continuous Rotation Servos.
  • The servos vary on internals... be flexible, some are through-hole and some are surface soldered.
  • Use the tweezers to hold the resistors as you solder.

  • Make sure you've got two CR servos ready by next class.

  • Need to clarify the notes on Continuous Rotation Servos.  There seem to be two kinds of servos... some have through-hole connections and some have surface mount pads. (a) note this, (b) add illustrations for surface mount pads.
  • Investigate getting SMD resistors for the second type of servo.
  • Need to ensure that (a) everyone has read/viewed material, (b) has done assigned homework so we don't need to catch up in class.

  1. When installing the Arduino Addons on Mac OS X:
    1) create a 'hardware' folder under your Arduino Folder
    2) drag the entire SF32u4_boards-master directory from the download into the Arduino/hardware folder
    3) Restart the Arduino IDE program. Under Tools->Boards you should now see two entries for SparkFun Arduino Pro Micro
