From the experimental work of 10 baht coin exchange machine controlled by infrared sensor, and ic74192 display 7- segment
.The principle of work of change 10 baht. Put the bill 20) into the channel receiver bill. The bill will examine whether by infrared seneor.Then the show on 7-segment by displays of money in and money out!
from experimental work and the experimental results are satisfactory. A prototype of a machine which can change 10 baht, controlled by the infrared sensor,Ic74192 display, and 7-segment For the further development and be applied in commercial or industrial. Associated with using coins, for example, change to use washing machine auto, car, electric carATM air compressors, aunt. Public telephone service and others
