Whee

Problem solved. After much testing we thought something strange was happening with the pins. But when I looked at the code it was setting the same pin twice in each test case. Whoops

Project Runway

For my project I am using a decoder 74ls139 I have it hooked up as follows
(I am going to link the images since they are super huge right now)
Decoder Arduinothe outputs can be connected to an led.

This is the truth table I got back, if you refer to the PDF the truth tables do not match (as indicated by the * ) Truth table
If anyone knows what's wrong, help!

Demo Video

This is what im get for playing with my camera

Pictures of the Chip Housing Unit

This is the front of my CHU, (now the full name isn't very creative, but the acryonymn is hilarious) Illustrating the holes for the ports

In this top view you can see the six peices of sticky tack used for fastening the board to the CHU and the CHU to a breadboard, the sticky tack can be moved to the other side to mount on the other side of the board.

Well it's 1:30 am. But I am finally finished. Pictures will follow. And Diagrams when I get to a scanner. I will bring it to class on friday.
Here's what it does:
1: the push switch turns the whole thing on or off.
2: The LDR determines the level of light and the led's light up according to where the light range falls.
will link the code at work tommorow.
