The controller features multiple modes that alter the behavior of MIDI controls, allowing for versatile customization of effects. \n\n- For setup and usage details, refer to the \"Usage Documentation\" folder.\n- For details on MIDI outputs, refer to the \"MIDI CC Assignments\" sections in the \"HaH_midi.h\" file\n\n![BOARD IMAGE](/Images/HaH_main.jpg)\n\n## Documentation Table of Contents\n- [General Usage](https://github.com/Karsten-Uy/HaH/blob/main/Usage%20Documentation/General%20Usage.md)\n- [Arduino and Electrical Setup](https://github.com/Karsten-Uy/HaH/blob/main/Usage%20Documentation/Arduino%20and%20Electrical%20Setup.md)\n- Modes\n    1. [Kirbeats](https://github.com/Karsten-Uy/HaH/blob/main/Usage%20Documentation/Modes/1-Kirbeats.md)\n    2. [FX](https://github.com/Karsten-Uy/HaH/blob/main/Usage%20Documentation/Modes/2-FX.md)\n    3. [Channel](https://github.com/Karsten-Uy/HaH/blob/main/Usage%20Documentation/Modes/3-Channel.md)\n\n## Features\nFor more detailed functionality see the \"Usage Documentation\" folder.\n- **Multi Mode Control**: Switch between Channel (CH) and Effects (FX) modes.\n- **MIDI Control Change (CC) Messages**: Has has following buttons and potentiometers that send specific MIDI CC messages for flexible control.\n    - 7 Select Buttons\n    - 1 Mode Select Buttons\n    - 1 Mute / Delay Tapper Button\n    - 3 Global Potentiometers\n    - 1 Expression Pedal\n\n- **Debouncing**: Smooth button presses to reduce unintended triggers.\n- **Potentiometer Calibration**: Adjustable sensitivity and threshold for accurate readings.\n- **Visual Feedback**: LEDs provide visual status of each mode and button press.\n\n## Components\n- **Arduino Pro Micro** - The microcontroller board.\n- **Select Buttons (Digital)** - Used for switching modes, effects, and channels.\n- **LEDs** - Provide visual feedback.\n- **Potentiometers (Analog)** - Used to adjust effect levels.\n- **MIDIUSB** - Libraries for MIDI communication.\n- **Physical Board** - Built with the following to structure and hold the eletrical components\n    - Paper Organizer for base\n    - Tape\n    - Macbook Box for structure and button covers\n    - Lego for pedal \n    - Trampoline Park Sock fir grip on pedal\n## Configuration\n- **Debounce Time (`DEBOUNCETIME`)**: Adjusts the debounce delay in milliseconds.\n- **Potentiometer Calibration (`POT_EX_START_VAL`, `POT_EX_END_VAL`)**: Defines the sensitivity range for the main potentiometer.\n- **MIDI Channel**: Configured via `MIDI_CHANNEL`, which can be changed based on your MIDI setup.\n\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkarsten-uy%2Fhah","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fkarsten-uy%2Fhah","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkarsten-uy%2Fhah/lists"}
