If you like science fiction then you definitely must have seen the Predator movie. How about having some of that high tech gadgets that actually works. What can be cooler than to have your own predator wrist watch that when pressed all the buttons would start the count down with all the sound effects. Or just having it laying it around showing the time on some distant planet.
These components will further subdivide into the control unit, input buttons, and five segments with nine LED on each. The control unit will house all the shift registers, micro controller, and resistors. Then each LED segment would be wired to the control unit.
Asia Engineer:We at least need 1, and technically we should use 2) for the power. We will need them for other power circuits as well. 3 is an assortment for the future. I think I have 2) here or we can get them off of other boards.
Dip socket for atmega328
Microswitch: get at least 2, but maybe we can use them in the design to add more switches?
.33 uF Capacitors For Power Supply: get at least 3
7805 Voltage Supply regulator 9vdc to 5vdc:

What is AREF?
How does one mathematically derive the capacitor values for decoupling?
What pins should we use to control the shift registers? We need 5.
What pins should we use to power the speaker?
Add two power sources.
Add programming header.
Switches requirements we need?
Capacitive Touch Sensor Reqs (for next gen)
