But I really hope you are not on the design team of one of my future
electronics equipment .
Usual they go bust just after the warranty expires.
Someone left out a resistor to spare some money.

Did you look at my circuit? It has resistors!! Very important. A lot of
people advise using a transistor buffer for extra safety.

Yes and yes. One is an example of an input and the other an output.
There is a lot of examples on the internet on Raspberry Pi GPIO's but
most of them talk about Python and/or wiringPi. We wanted to avoid
loading any more modules or libraries.

I am trying to add some normaly open push buttons to my piCorePlayer to
control play, pause, skip track and so on.
When I push the button for pause I want to send the pause LMS command
