Standalone Arduino 

Here are two drawings that show the pinout, or the location of each pin on the chip itself, of the Arduino microcontroller and the most basic circuit diagram. There are some tradeoffs by using this method, like having to program the chip in the Arduino before unplugging it and plugging it into the board. This page will be a work in progress until I get a few things ordered and have time to show the class how to make this all work and get some pics posted of the final thing. If your adventurous though, then knock yourself out.

You will need a couple of components to make this work:

16mhz Ceramic Resonator      Jameco# 324662

28pin DIP IC Socket                Jameco# 683171

You will also need a clean stable source of 5 volts DC. This means that you either pick up a switching 5v DC power supply from our favorite JK Electronics or you will have to wire up a voltage regulator. Page 254 of Phys Comp has a nice layout of a 7805 voltage regulator with a couple decoupling capacitors.

For the voltage regulator you will need these parts:

7805 Voltage Regulator         Jameco# 51263

10uF Electrolytic Capacitor     Jameco# 94220

1uF Electrolytic Capacitor       Jameco# 94160

Finally you will need something to stick all these parts into. Feel free to use anything you want, plastic, wood, a herring, but the easiest method is to use a copper clad perf board available at Radio Shack. These have holes drilled in a phenolic substrate with little copper rings, or pads, on one side.

213 Hole Mini Board        Radio Shack# 276-148  (This is small and square.) OR

417 Hole Board               Radio Shack# 276-150  (This is kinda like your breadboard.)

Ok thats all I have for now. I will have a better demo of this after our second critique.
