Pressure recorder is a arduino-python synthesizer that records pressure from different touch pads and plot real-time pressure data on the computer locally. Volume of output sound is determined by the amount of pressure applied on touch pads.

1. You will need Python 2.7 installed on your system.
2. Run: git clone https://github.com/lorrainechoi/Pressure_Recorder to clone the repo and then cd Pressure_recorder to navigate into the directory
3. Install Arduino IDE and upload the test_midi.ino file to the board
4. Install Python dependencies: numpy, matplotlib, serial, rtmidi_python, win32com, midiutil, py2exe

• numpy: pip install numpy
• matplotlib: pip install matplotlib
• serial: https://pypi.python.org/pypi/pyserial
• rtmidi_python: https://pypi.python.org/pypi/rtmidi-python
• midiutil: https://code.google.com/archive/p/midiutil/downloads
• py2exe: https://sourceforge.net/projects/py2exe/files/py2exe/0.6.9/

• Arduino Uno board
• Pressure Touch Pads / Force Sensing Resistors (FSR)
• Resistors

1. Connect Arduino to laptop through USB
2. Upload Arduino code to Arduino board
3. Open terminal, cd to Pressure_Sensor file and run script: python gui_windows.py

• Calibrate y-axis
• Mac friendly version

• Check MIDI - try to link to garageband (need to open virtual port)
• Build GUI: add stop button & and save csv file with file path input from GUI
• Build pressure sensing touch-pads
• Add MUX for location change

• Make touch pads to work wirelessly
