Add new riddles to the quest room. Assemble a gaming or vending machine. Just start saving for a vacation. A reference coin acceptor will come in handy in all these projects. Inside the acceptor, there is a slot for a reference coin or token. When a coin is dropped into the slot, it is compared with the sample in diameter and electromagnetic properties. If the characteristics match, the control system gives a signal to open the shutter. The coin falls into the coin acceptor, and a pulse is generated at the output of the device. If the coin does not pass the test, it returns through the return hole. In this case, there is no signal at the output. _______________________________________________________________________________________________________ User manual, examples and documentation: http://wiki.amperka.ru/%D0%BF%D1%80%D...
