We all want a cheap and easy arduino to play with, so most of us want to build it to save money or to put in pet projects.
I've spent hours online looking for a simple and easy one and in the end this is what i ended up with.
Most of this instructable is from this site >> http://fritzing.org/projects/diy-arduino/ << and i do thank them alot for what they put up.
Right let's get started shall we.
Some soldering skills are needed.
Material list for this Instructable:
1 Atmega 16 or 328p (i used a 328p)
2 Ceramic capacitors 22pF
1 Crystal 16Mhz
1 Resistor 10k 1/4w
5 Pieces of wire
1 28 DIP socket
1 7805 transistor
2 10uF/25V capacitor
1 9v battery connector
1 9v battery
1 Strip of female header pins
1 Minty box (i used a box from logitech that came with my wireless mouse)
Some glue (not important)
Drill for the dremel
Cutting discs for the dremel
Sorry for the lack of photos here but my phone ran out of power.
Move on to the wires and put them in the correct spot.
Add in the female header pins and solder them to the DIP.
And then solder the 9v connector in place. (remember to make a hole in the box you are using and thread the wires through it first)
Next, take the dremel and cut some slots in the lid of the box you are using. (the female header pins and IC goes through them)
I added some padding in the bottom of the box to avoid short circuits.
You could use a label maker to add the pin outs so it's easy to find.
Or download these, compliments of Adafruit.
You should be done by now.
Now then if someone figures out how to add a usb connection to this without using a FTDI please let me know.
