JOY STICK MODULE

The Joystick Shield Module is an Arduino Uno-compatible expansion board featuring a 2-axis analog thumb joystick, 6 momentary push buttons (A–F), and headers for Bluetooth (UART), I2C, nRF24L01, and Nokia 5110 LCD modules. Turns your Arduino into a game controller or robotic joystick interface.

Joystick:

• X-Axis → A0 (0–1023, centre ~512)
• Y-Axis → A1 (0–1023, centre ~512)
• Press button K → D8

Buttons (active LOW, pull-up resistors):

• A → D2, B → D3, C → D4, D → D5, E → D6, F → D7

Expansion Headers:

• Bluetooth: 4-pin header (3.3V, GND, RX, TX)
• I2C: 4-pin header (5V, GND, SDA/A4, SCL/A5)
• nRF24L01: 2×4 header (CE→D9, CSN→D10, SCK→D13, MOSI→D11, MISO→D12)
• Nokia 5110 LCD: shares D9–D13 with nRF24L01 (cannot use both simultaneously)

Specifications:

• Compatible: Arduino Uno and clones
• Supply: 3.3–5V
• Joystick: Dual-axis, 10kΩ potentiometers
• Pin pitch: 2.54mm

Applications:

• Robot and drone joystick controller
• DIY game console
• RC vehicle control interface
