RS232 Shield for Arduino

Recommended Posts

Hello, I wanted to first if the shield is compatible with the Arduino Mega board. Being currently on a draft bar code reader, I wanted to know how to program the board to retrieve the barcode on a lcd screen?
thank you in advance.

The RS232 shield is compatible with Arduino Mega board.

 

It's only a level shifter, you still need program the Arduino boards to realize what you want. And please remove the shield when you want to download program through the Arduino IDE.
