Description
The Motor Slave was designed to support an interactive art project with moving string weights.
It can control up to four DC motors simultainiously.
The quad encoder was added to each motor to give position feedback and a limit switch input
in provided to sense a home position for each motor.
Position control is through the FTDI serial and I2C interfaces. A PID control moves a given
motor to its commanded position.
A status LED is also provided.
- 8 MHz AVR ATmega164P
- 10pin header for each motor: quad encoder input and limit switch sense
- Seperate motor power bus
- AVR ISP programming header
- Status LED
