Hi everyone,
I just wanted to let you all know that we have upgraded from the Arduino Nano to the Arduino Micro (
http://arduino.cc/en/Main/ArduinoBoardMicro). The performance is better because the USB runs at a faster serial speed.
However, we are still using the same motor controller (
http://www.gravitech.us/2mwfecoadfor.html). The micro has 4 extra pins, but you can just leave these hanging off of the socket on the motor controller at the end away from the USB connector.
Happy haptics!
Best,
Edgar
