Final Wiring

Robot Challenge 2013Updated 10th October

Final Wiring Notes

• USE MASTERSKETCH_TEMPLATE• Motors and Motor Drivers• Ultrasonic Sensor• Line Followers• Tilt and Pan Servos• IR Obstacle Sensors• Wheel Sensors – Not Used

Motors

• Driver Board to Arduino

IN1 IN2 IN3 IN4

P6 P5 P12 P8

P12 P8 P6 P5

Motors

• Use MasterSketch_TEMPLATE• Motor Pinout for all sketches– int L1 = 6, L2 = 5, L3 = 12, L4 =8;

• Test – forward back spin left spin right – must be correct otherwise other sketches wont work

• This will allow motor speed variation – eg– forward(1000,150); where 150 is speed ( max 255)

UltraSonic Sensor

• Check the UltrasonicTest.ino sketch to make sure this is working

• Ensure you have NewPing library installed

Pin 15 V ( AREF) VCC

Pin 15 G (AREF) GND

A1 Trig ( Trigger )

A0 Echo (Echo, Echo, Echo)

UltraSonic Sensor

Line Followers

• Check the LineFollowerTest.ino sketch to make sure this is working

Tilt and Pan

• Use the MASTERSKETCH_TEMPLATE• Maxservo value 180• Min servo value 0• Midpoint 90

Tilt and Pan

• Use sensor shield pins 10 and 11• 10 Tilt ( Up and Down action )• 11 Pan Servo ( left to right action)

10 Tilt

11 Pan

Tilt and PanJust remember for servo – Yellow goes to sensor pin

Obstacle Sensors

• Use sensor shield pins 2 and 3 (Right and Left) • Use MASTERSKETCH_TEMPLATE to test this• Note no distance – only a switch
