The objective of this project was to design, build and test a vending machine
controller using a single chip microcomputer MC68705P3. The system consists
of several detectors (sensors) which detect which coin has been inserted.
The microcomputer counts and updates the total and displays this total
on an LED. As the display counts up in single increments, a beeper counts
off the number of cents in the coin. As soon as the count reaches some
preset total, the light/buzzer is activated. Once the switch is activated,
the microcomputer will reset to its initial value.
