Hi guys I just want to share about the problem I have experienced with my arduino,
Case: The project I am working is actually an Arduino coin acceptor to count the coins that I have inserted (pulse). It works fine in my first try and my Arduino components are new. But after so many attempts and changes when I try to make my Arduino data to be posted online the pulse is no longer accurate and now the pulse is no longer counting.
Q: Could it be my Arduino is damaged but I run basic program but it was still blinking or maybe there is a loose wire?
