Hey all, just wanted to show a small project i have completed for myself.
This was done for pure experimentation of a standalone arduino programmed via an FTDI
here are some pics
basic top view
same as above but from FTDI view
the underside
connected via FTDI to a USB-BUB
powered and ready
green LED lit by blink sketch (pin 13)
additional image showing smd led and resistors
top led = power (red)
middle led = tx (blue)
bottom led = rx (blue)
thanks!
if you notice in the first picture the resistor for the reset switch is soldered between one of the thru hole legs of the switch and the power rails directly (bottom left)
i think you are speaking about the ceramic resonator
it does the same job as a crystal + 2 caps. at least i haven run into any issues yet
last night i swapped out the green leds (they where actually dual - orange/green and gave me issues)
and managed to connect the pins 2-13 to the female header
Just wondering.....As i am also a curious noob....Why do you need that long resistor?... (corrected)
I am also trying to build an arduino standalone. And i am having some trouble finding all of the nessacary parts....where did you get yours? (btw....i have no idea how to burn a bootLoader...could i get a preburnt one from the same place you got yours?)
Oh..before i forget.....Was this hard?...i mean..... i dont even need the serial programming....i just need the....bare bones of the arduino....
Are you speaking of that 9 pin orange SIP resistor array? If so that is just a more compact was of using multiple resistors, if they are of the same value. Saves space and labor.

sooo....if i were making something similar.....would i do the same thing....attach resistors to each dig. Pin?
Only if you wish to drive a LED with the digital output pin. The resistor is to limit the current to a safe level.
Lefty
The resistors are not the output of the digital pins directly, take a look at the original image
there are additional wires going to the female harness without resistors
