Fingerprint Sensor with Arduino Mega 2560/Duemilanove

[CelsoPadilha]

Hello guys, my fingerprint sensor doesnt show life signal, just blink, I recorded one video to show how is happening.

I've read another topics saying about this problem, my cables are perfect, the ports are ok, I dont understand what the fingerprint sensor doesnt work. I need some help guys.

Someone has the same problem?


Cables:
Red = 5V
Black = GND
White = 3
Green = 4

The vídeo (The quality is sux but is possible to see) :

For some reason I can't play the video. Can you post a still photo showing your connections?

[CelsoPadilha]

I Can't post the photo now, because i'm working, but the wires conected are:

Red Wire = 5V on Arduino
Black Wire = GND on Arduino
White Wire = Digital port 3 on Arduino
Green Wire = Digital port 4 on Arduino

The same problem is happening in Arduino Mega 2560, the Arduino 2560 and Arduino Duemilanove works great, but when I connect the fingerprint sensor happen just one blink.

Are you connecting via a breadboard or direct to the Arduino headers?
Did you solder any connectors or pins to the ends of the sensor wires?

[CelsoPadilha]

I'm connecting direct to the Arduino.
Yes i'm did solder in all four conectors, and I tested all four with a multimeter and its all ok.

Today I'll post a picture.

The example sketch expects Green on pin 2 and White on pin 3. Have you modified the sketch? Looks like you're using pins 3 and 5 in the photos.

I changed to take a picture, this way of wiring happens the same problem.

[adafruit_support_rick]

In that case, have you tried swapping white and green?

[CelsoPadilha]

Yes, the problem still happening

[adafruit_support_rick]

The sensor won't light up unless it's actively scanning a fingerprint. What sketch have you loaded?
Also, the tutorial takes you through a setup process with Windows prior to attaching the sensor to an arduino.

Have you gone through that process? Did the sensor work then?

[CelsoPadilha]

Sry for the time to answer the question.

I try the tutorial and the problem was different. The problem are in the image:




I've seen other topics for this problem but, no one of this topics on adafruit forum doesnt work to me.

The COM Port are Ok and is the sensor port.

What I do?
