Hello every body,
I need help with writing an Arduino code for coin acceptor project. I will try to explain my concept about the project.
I need to made something like power switch timer for 220ACV using coins so I purchased a Relay Module for Arduino and Coin Acceptance Module CH-923 and configure it to accept three different coins, simply I need a code for my Arduino Uno board to open the relay for 5 minutes with coin #1 or open it for 10 minutes with coin #2 or 15 minutes with coin#3.
Any help please.
