Arduino Pin Connections
Following is the arrangement of pins on Arduino Uno:
- Analog Inputs:
- Analog Inputs:
- A0, A1, A2: Tape sensor inputs
- 10, 11, 12, 13: Contact switch inputs
- 3, 5: Enable PWM signals for the 2 motors
- 2, 4: Directions for the 2 motors
- 7, 9: Echo for the sonar sensors
- 7, 8: Trigger for the sonar sensors
- 6: Servo PWM signals
- Vin: +7.2 V from battery
- GND: ground from battery
