Progress

Ok, we are on the final phase of the project in terms of deadline :) It is supposed to be finished until Wednesday. So What do we have right now? Actually we can say, me and David started building whole stuff again from the stratch only we have quite a good experience in our heads about controlling multiple LEDs and stuff.

The images are blurry but you can get the idea overall. The objective is to build 25 LEDs and 25 switches on bottom of those switches, the LEDs are controlled through shift registers, we were thinking to do the same with the switches as well, though Jeff Gray gave me a great tip to use with switches. It is called Ladder something, basically you hook up the switches with the resistors and make sure they are in series with each other, an d when some switch is 1 state you can get the resistance until to it and compare its value with the sum of the resistance and you can get which switch it is, it is supposed to be in Tom’s book as well.

The LEDs are going to sit on the plexiglass hopefully :) Check the pictures out!
