Project 1 – Hardware
Elevator model contains 4 floors, single elevator shaft.
Elevator controller implemented using “pure” hardware:
• PIC microcontroller runs specialized algorithm;
• Hardware bundle: buttons, sensors, LEDs, RS232;
• GUI on the PC for signal display .

Project 2 – Software
Same elevator model as Project 1.
Elevator controller implemented using GUI driven simulation:
• Similar algorithm to Project 1;
• Developed in Visual C ++;
• Neat visual interface.

Project 3 – Hybrid
Differences from previous projects:
• Multiple elevator shafts;
• Keypad on the floors, not inside the lift cage;
Elevator controller implemented a combination of hardware and software:
• Algorithm;
• Dispatcher;
