I'm doing a mini-project for my course.
basically the requirement of this project is to convert the amount of money to the duration of parking.
for example,
Let's say the for 10 cents, the duration of parking would be 10 minutes.
And my problem is, would like to know how to convert the 10 cents into 10 minutes.
So far my idea is by using a few button switches(each switches indicates the amount of money. eg: switch 1 = 10 cents, switch 2 = 50 cents and so on). Once the switch is pressed, i would like it to convert into duration.(my guess would be using a 555 timer)
any idea on how can i do this? i believe this is simple so if anyone count point me in the right direction would be a great help!
thanks!
