node.js - Convert Audio to PWM signals (LRA Motor) -
i'm using macaron haptic design. here's demo here's github repo
i need guidelines on how rewrite macaron use websocket (node or python) process can send out pwm signals instead of amplitude/frequency audio stuff.
first considering using raspberry pi this, came across adafruit ft232h breakout - general purpose usb gpio+spi+i2c , use usb i2c rather whole pi. can run websocket server on local computer easier networking setup pi host web stuff.
what guys think?
