Pay Machine We need pay machine to allow customer to pay. Pay Machine have 2 section: 1. circuit to count the coins 2.Add program to connect the senor to the microcontroller to display the counting in the LCD
Components Count the coins Optical sensor 2- resistor (240Ω) 5Voltage Wire Jumper
Optical sensor The HOA2001 consists of an infrared emitting diode facing an Opto Schmitt detector encased in a black thermoplastic housing. The buffer logic provides a high output when the optical path is clear, and a low output when the path is interrupted.
