How do you read newer HDD motors (DC/Brushless) into arduino? (like stepper motors)


We had a version of the HDDJ working with an arduino reading an old stepper motor (with 4 wires), then sending serial data to processing, using a midi library, and midiox + midiyoke. Having trouble getting reliable forward/back speed data from the newer HDD's (2 or 3 wires), I think they are brushless DC motors? anyone had any experiance with this?


Cheers, Al

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
