Your problem is a very common problem: Bounce.

With a scope you will see it

In your code you will experience it

There are a lot of posts here and other locations; Google: "Key Bounce"

The factors of cost are: Producibility - How fast can you develop it Reliability/Resiliency - Does it work correctly and is it prepared for bad inputs Supportability - If it fails will you be able to diagnose Readability - Looking at it can yo...

What is the device you are connecting to? Brand, model Later your receive ma...
