Electrical Connections: Robot

NANO PIN CONNECTIONS

• D2 Bluetooth Module Rx
• D3 Bluetooth Module Tx
• D4 Beeper Signal (white wire)

• A0 Potentiometer signal (white wire)
• A1 Potentiometer Power (red wire)
• A2 Potentiometer Ground (black wire)

• A4 Servo Controller SDA
• A5 Servo Controller SCL

• 5V From Battery (the red Dupont connector coming off near the switch)
• GND From Battery (the black Dupont connector coming off the battery black wire)

Bluetooth Module Power

• V+ From the Nano 5V pin
• GND From either Nano GND pin

Beeper Power

• Connect the beeper V+ and GND pins to Port 14 of the Servo Controller, matching black and red wires to black and red pins on the Servo Controller.

Servo Controller

• Connect the 12 servos to port numbers corresponding to the servo marking (0 to 11). Make sure the signal wire (yellow) is oriented correctly.
• Connect the switch/battery module output to an unused servo port power and ground. Make sure the red wire is going to VCC and black wire to GND.
• On one short end you will find a VCC and VIN pin right next to each other. Use a shunt to connect those together. Both the servos and logic will run at +5V from the UBEC on the switch/battery module.
• SDA and SCL go to A4 and A5 on the Nano, respectively.

Electrical Connectons: Gamepad

NANO PIN CONNECTIONS

• D2 through D9 are connected to the button matrix pins.Looking from the top of the button matrix module, the rightmost button matrix pin goes to D9, second to right to D8, etc.
• D10 HC05 Tx
• D11 HC05 Rx
• A1 Dpad Signal (white wire)
• A2 Dpad VCC (red wire)
• A3 Dpad GND (black wire)
• VIN battery/switch positive (red wire)
• GND Either ground on the Nano goes to the battery/switch negative (black wire)

GAMEPAD: Screw Sizes

• Matrix button cover, 1/4" #6-32 screws (4)
• Yellow dpad buttons, 1/2" #6-32 screws (4)
• Gamepad Cover, 1" #6-32 screws (4)
