  • 2 servos for hands (Humanoid only) are connected to pin 6 and 7

• Buzzer is connected to pin 13

• Battery switch is connected with Vin and Ground to supply the Arduino board through battery power.

• Ultrasonic sensor is connected to pin 9 (Maker, Maker+ and Humanoid)

• Sound sensor is connected to Analog pin A6 (Maker+ and Humanoid only)

• Touch sensor is connected to Analog pin A0 (Maker+, Maker-Eye and Humanoid)

• 8x8 LED matrix uses pin A1, A2 and A3 (Humanoid only)

• Accelerometer / Gyro uses pin A4 and A5 (Humanoid only)
