Arduino controller DIY

My first Instructable is on how building your own Arduino controller!

You can build it on a breadboard, but i prefer to solder my own. For use with projects. This board wil not be able to program a ATmega chip. I use my original arduino for programming and use mye homemade boards in my projects. This reduces the cost!

Check out www.taydaelectronics.com for cheap components and fast delivery.!.

Step 1 What you need for the build

I used the following parts.

1x Solderboard
1x 28 PIN socket for the ATmega chip
1x ATmega 328 chip, preloaded with Arduino bootloader
1x 7805. 5V regulator
1x 10K resistor
1x red LED w/ 2x 100 OHM resistors
1x green LED w/ 1x 470 OHM resistor
2x 10uf capacitors
2x 22pf capacitors
1x switch (reset)
1x 16MHz Crystal
Wire for soldering
PINheaders

I want to something like this but with an external regulated +5v power supply.
How would the power connections change in that case?

In that case you can drop the first capacitor and the 7805. If you look at the first pic in the instrucable, you can see the power supply cable with the two pins. Just solder the negative lead direct on the ground wire on the board and the positive lead on the power wire. I hope this will make it work for you. If not. Just ask =)

A circuit diagram would be a good addition to your instructable.

Yeah, I´ll see what I can do the next days. Thanx for the comment ;)
