Adventures with Arduino Part 2

Following on from my previous post,  I have now made up one of the other projects in the handbook,  this time it is a LED lightbar,  8 leds,  each lights up in sequence left to right then back right to left.  Like on KITT from the 80’s TV series Knight Rider.

I have used yellow LEDs instead of red LEDs.

 

As a footnote to all this,  breadboard jump wire is very handy,   as is having LOTS of breadboard jump wire like below 🙂
