hi how to use multiple shields in Arduino?

if i have two…

example, GSM and Ethernet can this work simultaneously in void setup?

void setup(){

Serial.begin(9600);
    if (gsm.begin(2400)){
        Serial.println("\nstatus=READY");
        started=true;
    }
Ethernet.begin(mac, ip);
server.begin();

}

Hi,

I think that all you need to worry about is using NewSoftserial for the second baud rate.

Also if you have hardware overlap, you can use the Go_Between shield to remap your pins
