Example Sketches and Notes for Carleton College

Servo_5_Sweep Sketch:

Runs 5 servos attached to pins 8-9-10-11-12 through 180 degrees, medium then fast.
 
  RedBack Controller input current to external power connector:
 
  9V 1 A Power Supply 0.5 Amps
  12V 2 A Power Supply 0.3 Amps
 
  Cut and paste following sketch into an Arduino IDE window.
 

/* YourDuinoStarter Example: 5 Servos Sweep
 - WHAT IT DOES
   Sweeps 5 servos on pins 8-9-10-11-12 through 180 degrees
 - SEE the comments after "//" on each line below
 - CONNECTIONS:
   - Servos on 3-pin connectors on YourDuinoRobo1 or RedBack
   - MUST use External Power connector and 9 to 12V power supply
 - V1.00 12/09/2013
