USB Closed-Loop DC Motor Controller

My bachelor project: "Design & Implementation of a USB-Interface and a Closed-Loop Controller to Monitor and Control the Speed of a DC Motor in Real-Time." A USB interface let a computer program communicate with the external device; the hardware was designed and tested in Proteus, laid out in Protel DXP, then produced and implemented, with control software on the PC side.

BSc final project, scored 20/20.
