Arduino Joystick Data Visualization

This Python script visualizes joystick data from an Arduino board using PyFirmata, Matplotlib, and Py-IIR-Filter.

Requirements

• Python 3.x
• PyFirmata 2.x
• Matplotlib
• NumPy

Install the required Python packages using pip:

pip install -r requirements.txt

or

pip install pyfirmata matplotlib numpy

Usage

Note: Start from step 3 if you already have the project files.

1. Clone this repository:

   git clone https://github.com/JalalSayed1/IIR-filters.git

2. Navigate to the project folder:

   cd IIR-filters

3. Connect your Arduino board to your computer.

4. Connect a joystick to your Arduino board.

   • Connect the X-axis to analog pin A0.
   • Connect the power and GND pins to the board's 5V and GND pins.

5. Connect two RB LED's to your Arduino board.

   • Connect the red pin on one of the LED's to digital pin 5.
   • Connect the blue pin of this LED to digital pin 6.
   • Connect the other RB LED to the same pins but swap the red and blue pins (to make a switching effect).
   • Connect both GND pins to the board's GND.
   • No resistors are needed.

6. Run main.py script:

   python main.py

   The script will start visualizing the joystick data on a Matplotlib graph in real-time and another small window will appear with a button to toggle between using raw data or filtered data to update the LEDs in real time. The actual sampling rate is displayed in the terminal.
