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.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
