I'm not very experienced using my Arduino with anything other than LEDs so my final project for school is proving to be interesting. We have lights, buttons, servos, and limit switches, which we've tested and are fine. The highlight of our project is a barcode scanner.
Originally we were going to use a PLC but we felt like we didn't have enough time to debug with it. So now I have a serial barcode scanner in the mail and I've been researching on how to bring it over to this project with the Arduino.
I found this thread which seems to be what I'm looking for but I'd like some more clarification: http://arduino.cc/forum/index.php?topic=21168.0
I understand that I will need a converter to have it use the correct voltages for the Arduino. Is this the correct adapter? http://www.robotshop.com/dfrobot-rs232-ttl-adapter.html
The seller of the barcode scanner told me that it comes with the data cable. Are serial barcode scanners powered by the db9 cable?
From the converter, all I need is the Rx and Tx to the corresponding pins on the Arduino. Anything else?
