You have no void setup() or void loo() !

If you have a meter - check the components around the ftdi, if all measures OK then plug in to usb and chase the voltages. You can send them here to be tested/repaired (may not be worth it for P&P).

Hi - it's println not printIn   (letter L not letter I)

Did you remember to install the softserial library in the correct location (your arduino sketch directory/libraries)!
488  Using Arduino / General Electronics / Re: Breadboard-friendly power connectors? on: January 12, 2013, 01:20:11 pm
Yip - I got 2 - one on each power rail - can do 5V & 12V on same board ;-)
489  Using Arduino / General Electronics / Re: Breadboard-friendly power connectors? on: January 12, 2013, 01:11:53 pm
I bonded one of these to a breadboard, and soldered jumper wires to the pins, and inserted them into the rails.

Have you got pull up/down resisters installed?
491  Using Arduino / Microcontrollers / Leonardo as ISP on: January 04, 2013, 05:45:46 pm
Hi all, I've been struggling to get my new leonardo to work as an ISP programmer. But finally found out what I was doing wrong.

1. The ICSP pins are not broken out to digital pins - Use the 6 pin header - mosi->mosi, sck->sck etc
2.1 Need to modify the Arduino as ISP sketch - find #define RESET SS, and replace SS with 10 (The reset from the TARGET connects here)
2.2 I've saved the sketch as LeonardoISP - in the Examples Directory - Easy to find (Also works with the UNO)
3. modify the programmers.txt file (its in the arduino folder-hardware-arduino, include :

leo.name=Leonardo as ISP
leo.communication=serial
leo.protocol=arduino
leo.speed=19200

at the end of the file

Upload the Arduino as ISP sketch to the leonardo
Load/Type your sketch
select the target chip type
Click 'Upload Using Programmer' or 'Burn Bootloader'

Hope this helps.

Edited to update Info.

Follow this logic :
if I read high - set (triggered=TRUE)
if I read low while triggered=TRUE set (triggered=FALSE)
if triggered=HIGH and done=FALSE - DO SOMETHING,then set done=TRUE
start again

Hope this helps

I assume you have tried a loopback test?
if not, try that first.
OK - try this :
(Make sure you have the correct board & com port selected)
& make sure your board is not laying on top of something metal (I've been caught by this one)

Press upload on the ide
when the sketch size comes up, tap the reset button on the mega
if this works, then its probably the reset cap is faulty

if not - it may be the bootloader is faulty - do a search for using your UNO as an ISP,
try re-uploading the bootloader, If it's still faulty, I recommend arranging for a replacment
from your supplier.

494  Using Arduino / Microcontrollers / Re: Decided to build a dedicated dedicated programmer, advice needed :) on: January 03, 2013, 06:49:42 am
I make these, the new ones have a zif socket, no 8 pin header (now duel support on the zif). Needs a Duemilanove or UNO, will not work on the mega 1280/2560 or leonardo.
I don't have a photo of the new one yet, my camera is at work.

When you try to upload with the arduino ide, what error message do you get? is the board an official one? Have you installed the correct drivers? have you tried a different usb port/cable?
