This is the first part of a two parter on creating the K.I.T.T. light bar with LEDs using your Pi (I know, awesome, right?).
Here’s mine in action:
In this section we’ll install the wiringPi library on the Raspberry Pi, connect up a single LED, and write a simple program in C to make it flash.
In part two we’ll connect up more LEDs, expand the code, and then travel back to the 80s with our finished product.
