DomStick: Bluetooth Game Controller PCB Based on Arduino Nano

The DomStick Bluetooth Game Controller PCB is a versatile and compact solution for wireless robotic control, DIY gaming projects, and Arduino-based applications. Built around the Arduino Nano, this PCB integrates a joystick, buttons, and a Bluetooth HC-05 module, allowing you to create a fully functional wireless controller for robots, drones, or other electronic projects.

Designed with hobbyists, students, and makers in mind, the DomStick offers easy integration, flexibility, and reliable performance for Arduino enthusiasts looking to add Bluetooth control to their projects.

Features

Buttons with Internal Pull-Up

All buttons on the DomStick PCB are connected directly to ground without external pull-up resistors. To ensure proper operation, you simply enable the Arduino Nano’s internal pull-up resistors on the input pins. This design choice simplifies the circuit and reduces component count while maintaining stable and responsive button inputs.

Joystick with Dual Axes

The joystick on the DomStick includes two axis-controlled variable resistors (X and Y axes) and a push button. Like the other buttons, the joystick button is not connected to an external pull-up resistor, so the Arduino Nano’s internal pull-up resistor should be enabled for accurate readings. This allows for precise directional control and smooth analog input for robotic movement or game control.

Bluetooth HC-05 Module

The DomStick uses the popular HC-05 Bluetooth module, configurable in Master-Slave mode. This enables wireless communication between your Arduino Nano-based controller and your robot, drone, or other compatible devices.

To protect the HC-05’s 3.3V RX pin, the DomStick PCB includes a voltage divider with three resistors to safely step down the Arduino’s 5V TX signal to the appropriate 3.3V level. This ensures safe, reliable communication and protects the Bluetooth module from voltage damage.
