Connect GSM Shield and Arduino using Jumper? #22

Closed ronistiawan closed 9 years ago

ronistiawan commented 9 years ago

what pins do I need to connect to use GSM shield and Arduino separately?

madmaze commented 9 years ago

if I remember correctly, you only need the serial/datapins and power hooked up.

You can also change the datapins here: https://github.com/MarcoMartines/GSM-GPRS-GPS-Shield/blob/GSMSHIELD/GSM.cpp

I've connected the serial pins. which one is the power hooked up pin?

madmaze commented 9 years ago

that depends, which board do you have?

ronistiawan commented 9 years ago

Arduino Mega 2560

Why the GSM Shield can only works if I use the power from Arduino?
