The Raspberry Pi’s IO ports (GPIO) are not that easy to access, so they make a nifty way to prototype circuits like what I am trying to do.
I also learned about a utility that is part of a C library called wiringPi which is one of a few that lets you easily access the GPIO input and output pins in a similar manner as how you access pins on the Arduino.
wiringPi comes with a really cool utility called gpio, and it lists all of the pins on the GPIO and their state.
I am learning so much more and so much faster than I ever learned anything in my DXCC chasing days. Holy smokes.
