Dance Messenger

Step 1 The circuit board

I used a fairly generic circuit board I had lying around for this project. The circuit is really simple though, just an Atmel AVR microcontroller, 10 LED's, a programming header and a few resistors and capacitors. maybe a button if you want to be able to turn it off. The board I used is mostly surface mount components, but all the parts are available in thru-hole form so you could easily build this up on a proto-board.

I've attached below the Eagle CAD (http://www.cadsoft.de/) files for the circuit board, the C source code for the microcontroller, and the Gerber files of the circuit board to get it manufactured. Eagle CAD is free for small-size boards like this one.

Parts used:
Atmel mega8L microcontroller - digikey ATMEGA8L-8AC-ND
6-pin .1" spacing pid header - digikey WM6806-ND
1206-size surface mount LED's in color of your choice - digikey 160-1406-1-ND, 160-1404-1-ND, 160-1402-1-ND
150 ohm resistor array: digikey EXB-V8V150JV
10uF 0805 size capacitor: digikey 587-1299-1-ND
switch: digikey CKN4081CT-ND

hai i am boday from INDONESIA.. i want to know in your project "DANCE MESSENGER", in "the Circuit board step" you say :L1, C1, and C3 -->"Dont need these for this project" the orange wire and X1,X2, and X3-->"Not used" what must i do to this component?? can i "short" them??(i mean Like use jumper??) thank for you answer...

dont put anything there. no connection.
