GamePad - Wireless Controller

GamePad turns your Android phone into a wireless Bluetooth Low Energy (BLE) game controller. Designed for students, makers, and hobbyists, it connects to microcontrollers, robots, RC cars, and other BLE-enabled devices.

FOUR CONTROL MODES
Pick the layout that fits your project:

- Joystick: Dual analog sticks with precise X/Y control. Perfect for omnidirectional robots and drones.
- Classic: D-Pad + four action buttons (Triangle, Square, Circle, Cross) plus Select & Start. A familiar console-style layout.
- Steering: Realistic steering wheel with gas and brake pedals. Supports tilt control using your device's accelerometer.
- D-Pad: Simple 4-way directional pad with A and B buttons. Great for basic navigation and two-action projects.

BLUETOOTH LOW ENERGY
Connects wirelessly to any BLE-compatible device. Works as both a BLE Central (connects to peripherals) and BLE Peripheral (advertises and accepts connections). Low latency analog data streaming at 50ms intervals.

BUILT FOR LEARNING
Created as a companion app for the CodeSkool programming environment. Students can use GamePad to control their Scratch-programmed robots and interactive projects. The matching CodeSkool extension makes it easy to read controller inputs in block-based code.
