Step 1: Material Needed

for this you will need...
1] dotted pcb
2] 70 led [coloured]
3] MSP430G2553
4] 2x 74595 shift register
5] 2x DPDT switch
6] 4x micro switch
7] ic bases
8] potientiometer 4k7
9] decoupling capacitors [104]
10] on\off switch
11] 8x BC547
12] 8x 1k res.
13] 5x 10k res.
14] 4v battery
15] ti launchpad
16] ti Code Composer Studio

Step 2: Layout

then you have to select the positioning of your 8x8 led matrix and all other components according to your PCB...

Step 3: Building the 8x8 Med Matrix

you can get instructions how to build an LED matrix on many pages on the internet, here is the process, by which i made it....

Step 4: Making Connections

its the hardest part of building the hardware, and you must be careful about making the exact same connections as i made, otherwise the code wont work on it, i have uploaded an eagle's schematic file, with the diagram which shows the essential connections which are to be made EXACTLY the same way...
