Well, thanks once again a lot for your suggestions! After a lot of hours, i finally managed to make it work as i want. Before describing my new problem, let me do a little introduction of my project...I have to make a vending machine with 3 positions (for 3 products) and my problem is how to move a servo when only the right value has been inserted in the coin acceptor...For example, the 1st position need 50cents, the 2nd needs 80cents and the 3rd 1 euro & 30 cents.It sounds easy but when i tried to do it with (if...else if) things didnt go as i wanted. In the attachment below, it's the code i've made on my own...excuse me for that question cause it sounds easy but i'm a little new one on arduino...When i insert 50cents, i have a green led that lights up, so that means it is ready to move the 1st servo...but if i want to insert 80 cents it doesnt let me move the 2nd servo. Of course, i will continue to search it on my own until i find a solution.
I tried to write a lot of commends to understand the whole situation as more as u can.
Thanks a lot for your time!
