Funduino Joystick Shield

The Joystick Shield kit contains all the parts you need to enable your Arduino with a joystick! The shield sits on top of your Arduino and turns it into a simple controller. Five momentary push buttons (4+ joystick select button) and a two-axis thumb joystick gives your Arduino functionality on the level of old Nintendo controllers.Features2-Axis joystick4 large buttons2 small buttonsBluetooth / Serial interfaceI2C interfacenRF24L01 interfaceNokia 5110 LCD interfaceInterface connectorPower switch to switch between 3.3 V and 5 V2-Axis JoystickThe X-Axis potentiometer of the joystick is connected to A0. The Y-Axis potentiometer is connected to A1. The joystick also has a button K which is activated by pressing the joystick down. This button is connected to D8.Buttons:There are a total of 6 buttons on the board (not including the one on the joystick) labeled A-F. The 4 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 / less likely to be pressed accidentally. All buttons have pull-up resistors and pull to ground when pressed.Button A Connects to D2Button B Connects to D3Button C Connects to D4Button D Connects to D5Button E Connects to D6Button F Connects to D7Bluetooth ConnectorThe RX/TX lines are brought out to a separate 4-pin female header along with 3.3 V and Ground. This can be used for connecting a 4-pin 3.3 V Bluetooth device or a TTL serial device.I2C ConnectorThe 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 ConnectorThis connector allows an nRF24L01 RF transceiver module to be plugged in.GND Ground.VCC 3.3VCE Connects to D9CSN Connects to D10SCK Connects to D13MOSI Connects to D11MISO Connects to D12IRQ No ConnectionNokia 5110 LCD ConnectorThis female header connector is designed to mount the Nokia 5110 LCD that was originally designed for Nokia phones and provides a 4884 pixel matrix.This interface occupies the same D9-D13 pins as the nRF24L01, so you cant use both at the same time.Interface ConnectorThis dual row yellow male header connector provides another point of access to all the buttons, joystick pots, 3.3 V, 5 V and Ground. The pin-out of this connector is labeled on the board to the left of the connector.SchematicExample Code
