/* This code is created by Shengzhi Wu (www.wushengzhi.xyz) for Responsive Mobile Environment class project Aura Carbon
It used a PowerMate dial to trigger various pieces of conversations and communicate with a Particle Photon to change light effect of a 24 NeoPixel
All you need to change is to find the correct serial port, it is in line 67, just change the number
You can use line 72 to print all the availiable port,  and find the one starts with usb
the PowerMate uses a U and D key to trigger the changes, so you need to use PowerMate app and change it to mimick press key "U" and "D"
