it is based on ldr (light dependant resistor) the system makes use of a sensor for detecting
the coin and a microcontroller that counts the coins and shows the count on a
7-segment display. When you close the load switch provided in the circuit, the
relay energises to connect the load and the coin count on display starts
decrementing. When the count decrements to zero, the relay de-energises to
disconnect the load

I have no idea what a "PCO" is, but you should search this site for "coin mechanism".

Maybe I'm just daft, but what's a pco?
