Step 4Building the Control Unit hardware
Once I had finished the three towers, it was time to build the control unit. As I explained at the beginning of the text, the control unit is a black box composed of three electronic boards. The main board contains the logics, the serial communication adapter ( 1 MAX-232) and the microcontroller (an ATMega32 8 bit RISC microcontroller ). The other two boards contain the circuitry needed to control the position sensors ( some resistors and 3 triggers-schimdt 74LS14) and to power the motors ( 3 LB293 motor drivers). You can take a look to the schematics to get more information.
