This creates a delay in the pulse due to the time it takes to charge and discharge the capacitor.Ī capacative sensor works in the same way as a capacitor. When the signal goes to zero, the capacitor discharges. When sending a pulse to the capacitor, it quickly charges. The capacitor can be compared to a small battery. Between these surfaces there is a non-conductive layer wich is called a dielectric. To understand how capacative sensors work, first you have to understand how a capacitor works.Ī capacitor consists of 2 electrical conductive surfaces (also called electrodes), one is connected to the positive pole of the electrical circuit and the other is grounded. Grounding pins 4 - 11 cause the hat switches to change position.Before we move on to the fun (but mostly frustrating) projects you can embark on with capacitive sensing, let's take a quick look at how it really works. HatSwitchTest - Creates a joystick with two hat switches. GamepadExample - Creates a simple Gamepad with an Up, Down, Left, Right, and Fire button.ĭrivingControllerTest - Creates a Driving Controller and tests 4 buttons, the Steering, Brake, and Accelerator when pin A0 is grounded.įlightControllerTest - Creates a Flight Controller and tests 32 buttons, the X and Y axis, the Throttle, and the Rudder when pin A0 is grounded. Maps pin 9 to Joystick Button 0, pin 10 to Joystick Button 1, pin 11 to Keyboard key 1, and pin 12 to Keyboard key 2. JoystickKeyboard - Creates a Joystick and a Keyboard.
JoystickButton - Creates a Joystick and maps pin 9 to button 0 of the joystick, pin 10 to button 1, pin 11 to button 2, and pin 12 to button 3. MultipleJoystickTest - Creates 4 Joysticks using the library and exercises the first 16 buttons, the X axis, and the Y axis of each joystick when pin A0 is grounded. It exercises many of the Joystick library’s functions when pin A0 is grounded. JoystickTest – Simple test of the Joystick library. These will appear in the Arduino Example menu when the Arduino Joystick Library is installed. The example Arduino sketch files listed below are included in this library.
