Cub scouts need some guidance.

PennState'R

Hello, I am a cub scout pack leader and our den has been asked to build a project for our upcoming pinewood derby race in 2 weeks.· We have been asked to build a starting gate christmas tree like you would see at a drag racing strip.· Our track has 4 lanes and we are designing our christmas tree to have 4 individual light sequences.· We have prototyped our electrical circuits on a prototype board with jumpers to·the BS2 Inputs/outputs.· We are using 8 Darlington Arrays, and 24 lights made up of 24 leds each and 2 external 24volt 2.5amp power supplys.· Our tests seem to work very well with the program I have attached below.· Since no one in our pack is experienced with electronics, we have a couple of questions that we need direction or guidance on.· First, how does our code look?· We made the code up completely from the first couple of chapters in the BS2 manual.· Second, I know that we do not want to permanently attach the BS2 to the christmas tree, how do we take the code we wrote and the circuits we made and put them into the christmas tree so that its a stand alone device?· We need all 16 I/O ports and we need to have 5 volts somewhere for the switches.

Here is our code:
