In this tutorial we will be looking at our first GPIO (General Purpose I/O) programming with the gcc C compiler.  Library files and pin out information for the raspberry pi can be found at the links below.

<p>I can't really see what's written on your screen.. =(</p><p>But congratulations for your project!</p>
<p>Its a simple bit of code, which turns the GPIO pin on and off, by <br>setting it to low and high in a while loop and a timer between the two <br>what sets the pin. For this you can find many examples in python and is <br>fast enough to do this but if you want to work with range finders as i <br>am then C is the way to go. I do agree its far too small to read and to <br>be honest he should of enlarged it before creating his video</p>
