I am trying to activate 3g/gps shield with push button on arduino mega 2560
i am beginner, i've got the following errors:
sketch_may01a.ino: In function 'void loop()':
sketch_may01a:29: error: a function-definition is not allowed here before '{' token
sketch_may01a:256: error: expected }' at end of input sketch_may01a:256: error: expected }' at end of input
can any one help me please!!
Thanks in advance..
here is the code:
const int buttonPin = 12; // the number of the pushbutton pin
const int ledPin = 13; // the number of the LED pin
// variables will change:
int buttonState = 0; // variable for reading the pushbutton status
void setup() {
// initialize the LED pin as an output:
pinMode(ledPin, OUTPUT);
// initialize the pushbutton pin as an input:
pinMode(buttonPin, INPUT);
}
void loop(){
// read the state of the pushbutton value:
buttonState = digitalRead(buttonPin);
// check if the pushbutton is pressed.
// if it is, the buttonState is HIGH:
if (buttonState == HIGH) {
//digitalWrite(ledPin, HIGH);
