Arduino code for coin slot with led matrix timer

We are currently working on our project. We are trying to use a coin slot and the time will depend on the amount of coins inserted. The value of coins are 1,5 and 10. The value of 1 is to 2 mins, 5 is to 10 mins and 10 is to 20 mins. Hope you can help us. Thanks

Hi, Welcome to the forum.

To help you, you will need to show us what code you have written. What model arduino you are using. What hardware you have connected and a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?

Please read the first post in any forum entitled how to use this forum.,148850.0.html then look down to item #7 about how to post your code. It will be formatted in a scrolling window that makes it easier to read.

We can advise and guide you, but you must show some code towards your project.

Your first stage is to get the code written to accept the input from the coin device. Do not try and write all of the code at once.
