Hello, my first post.
I am simply (in theory) wanting to send one of three pre-selected messages when one of three buttons are pressed. (3 buttons to send 3 different messages and one LED to alert the message has been sent) See the attached code to look at what I have done so far...
my issue is using a push button (momentary) to add value to my three (defined at top);
int button1press
int button2press
int button3press
i know I need to do something like:
if b1pin = high
button1press ++
else
if b2pin = high
button2press ++
else
if b3pin = high
button3press ++
or something like that... but I need help incorporating that into my code, I would really appreciate any help you could give. I have done most of the hard work I think it's just incorporating the above to trigger the code I already have attached.
Thanks in advance.

From the code, I cant see any code that read the button Press.
You should do some thing like.
void loop(){
button1Press=digitalRead(b1Pin);
button2Press = digitalRead(b2Pin);
button3Press = digitalRead(b3Pin);
if(button1Press==HIGH){
//send sms 'button1 pressed'
button1Press=LOW;
}
else if(button2Press==HIGH){
//send sms 'button2 pressed'
button2Press=LOW;
}
}
