Traffic light
Hi!
I am new to scratch and the world of programming! I have seen that you can create a traffic light program and link it up to a raspberry pie. could someone please help me in
a) setting up the trafficlights in Scratch
b) linking it with my raspberry pie and breadboard.
As simple as possible please.
thank you

Re: Traffic light
Hi Claire - Just to show that I know a bit about this 
http://www.scratch.mit.edu/ext/youtube/ … ;feature=*
One way of getting going is to draw a new sprite with the 3 coloured lights in it, copy the first costume 3 more times and then fill in the coloured lights so you are left with a red one,amber one,green one and one with red AND amber (I'm in UK - don't know if same where you are)
Then write a little script that just uses the next costume blocks and some wait blocks to go through a traffic light sequence

Re: Traffic light
Here is some info on getting Scratch talking to GPIO ports on your RaspberryPi using what is called a helper type program written in Python.
