Now, you can easily add an HID/controller to your project! The SparkFun Qwiic Joystick combines the convenience of the Qwiic connection system and an analogue joystick that feels reminiscent of the thumbstick from a PlayStation 2 controller and for that reason it's become a favourite of ours. The only thing that could make it better is a "smart" version, so we made one! With the pre-installed firmware, the ATtiny85 is acting as an intermediary (microcontroller) for the analogue and digital inputs from the joystick. This allows the Qwiic Joystick to report its position over I²C. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

The joystick is similar to the analogue joysticks on PS2 (PlayStation 2) controllers. Directional movements are simply measured with two 10 kΩ potentiometers, connected with a gimbal mechanism that separates the horizontal and vertical movements. This joystick also has a select button that is actuated when the joystick is pressed down. The SparkFun Qwiic Joystick's I²C address is also software selectable so you can plenty of them to the same bus without any risk of collision!

NOTE: The I²C address of the Qwiic Joystick is 0x20 and is software configurable. A multiplexer/Mux is required to communicate to multiple Qwiic Joystick sensors on a single bus. If you need to use more than one Qwiic Joystick sensor consider using the Qwiic Mux Breakout.
