Live feed to COM and LIVE OUT to NO

Where COM is the Common connection & NO is the normally open connection.

No problem, you have our permission.

It's a optical sensor.

PLEASE supply a link as asked for, we are not mind readers.

*** Still not a GUY ***
Can you select verbose output and  post the full report including the line with the AVRDUDE call please.
5  Using Arduino / Project Guidance / Re: how to connect fingerprint sensor to arduino uno on: August 29, 2014, 03:25:17 pm
Use wires!

What information are you looking for? The wiring is shown in the images, without a datasheet - anything else would be a guess.
6  Using Arduino / Programming Questions / Re: 16x2 LCD + expander PCF8574 on: August 29, 2014, 01:40:49 pm
I thought it used Analog 4 & 5 (I2C)?
7  Using Arduino / Installation & Troubleshooting / Re: connecting to computer on: August 28, 2014, 04:47:52 pm
Many thanks for telling us.

Please supply ALL the information to help you.

Is it an official board (if not - supply a link to where it was purchased)

has it ever worked?

what have you tried (so we don't waste time asking you to try things)

what operating system do you have?

what IDE Version do you have?

have you tried reinstalling the drivers? have you tried a new USB cable? a different USB port? Have you made sure you have the correct COM port selected as well as the correct board?
8  Using Arduino / Installation & Troubleshooting / Re: Can't Select "Arudino Due" from Tools - Board Menu? on: August 28, 2014, 10:19:41 am
Try a newer version (1.5 or newer)
9  Using Arduino / Installation & Troubleshooting / Re: Can't Select "Arudino Due" from Tools - Board Menu? on: August 28, 2014, 09:56:11 am
What version of the IDE are you using?

but the device won't start

How are you determining this? If it runs blink, it will work, so has to be your (unposted) code or what you have hooked up to you circuit.

If you could supply both, this would help us a lot.  smiley-wink
11  Using Arduino / Installation & Troubleshooting / Re: I can't get the tone library to load !!urgent!! on: August 28, 2014, 06:08:14 am
Please post the code you are trying to compile.
12  Using Arduino / Microcontrollers / Re: Standalone ATMega2560 Sketch Upload Problem on: August 25, 2014, 09:23:29 am
Do you have a cap on the reset line? what happens when you tap reset when your sketch is ready to upload.
13  Using Arduino / Microcontrollers / Re: Bootloader Arduino mini Pro 3.3V 8Mhz, Upload sketch, weird on: August 25, 2014, 08:06:22 am
This is usually a symptom of not setting the lock  after uploading the bootloader.
14  Using Arduino / Project Guidance / Re: can this GPS can work with Arduino? on: August 25, 2014, 04:47:08 am
Yes.
15  Using Arduino / General Electronics / Re: attiny85 + pir sensor power consumption on: August 22, 2014, 06:11:40 pm
connect a multimeter in series with your power supply & measure it, without you supplying the data sheets, it's a guessing game.
