This JoyStick Shield Module for Robotics Control is an Arduino Uno-compatible shield that allows you to turn an Arduino Uno or compatible into a game console or robotic controller. 3.3V to 5V Gamepad Joystick Shield Module Game Rocker Button Controller Expansion Board For Arduino Simulated Keyboard Mouse Module.

The shield sits on top of your Arduino and turns it into a simple controller. 7 momentary push buttons (4 big buttons + 2 small buttons + a joystick select button) and a two-axis thumb joystick give your Arduino functionality on the level of old Nintendo controllers.

2-Axis Joystick:

• The X-axis potentiometer of the joystick is connected to A0. The Y-axis potentiometer is connected to A1. The analog inputs on a microcontroller read values over a range of 0–1023 (for typical 10-bit ADC inputs). The X-axis and Y-axis controls should read around 512 (the midpoint) when the control is at rest. As the joystick is moved, one or both of the controls will register higher or lower values, depending on how the control is being moved. The joystick also has a button ‘K’ that is activated by pressing the joystick down. This button is connected to D8.

Buttons:

There are a total of six buttons on the board (not including the one on the joystick) labeled A-F. The four large buttons are typically used for up/down, left/right, or similar functions. The two smaller buttons are typically used for less commonly used functions such as'select' or'start' since they are less accessible or less likely to be pressed accidentally. All buttons have pull-up resistors and pull to ground when pressed.

• Button A: Connects to D2
• Button B: Connects to D3
• Button C connects to D4
• Button D connects to D5
• Button E: Connects to D6
• Button F: Connects to D7

Bluetooth Connector:

• The RX and TX lines are brought out to a separate 4-pin female header along with 3.3V and ground. This can be used for connecting a 4-pin 3.3V Bluetooth device or a TTL serial device.

I2C Connector:

• The I2C SDA and SCL lines are brought out to a separate 4-pin male header along with 5V and ground. This is in addition to the normal A4/A5 location of these lines. This allows for easy attachment of I2C devices.

nRF24L01 Connector:

• This connector allows a nRF24L01 RF transceiver module to be plugged in.
• 2 x 4 Female heads
• GND = ground.
• VCC 3.3V
• CE: Connects to D9
• CSN: Connects to D10
• SCK: Connects to D13
• MOSI: Connects to D11
• MISO: Connects to D12
• IRQ: No Connection
