Bluetooth code with another code

Using Arduino Networking, Protocols, and Devices

can i add a code include if statement with bush button to a code receive some state by bluetooth from another arduino

2

If you can describe it, you can probably do it - you don't have to ask for permission.

3

i have a code for bluetooth it has a serial available code that receive a character from another Arduino to do something ........ so for this Arduino i want to add bush button on it to turn on the led , when i add the code that contain a bluetooth code for the code how contain a bush button code it doesn't work , i don't now why

4

No, me neither.

5

is there any solution ?

6

I don't know - I can't see what you tried.

7

Want you want to do is possible but you don't know what you are doing, and nobody else does either. Post your code, and wiring, then you might actually get some help.

this is my code , the upper part for the arduino and the lower part is for bush button

{
digitalWrite (led1 , HIGH);
digitalWrite (led2 , LOW );

You have called the software serial library but are not using it. You might not actually need it but, with the absence of any wiring details, who would know?
