I am trying to do use two bluetooth modules to control an LEDs. I am using HC05 as master and another as slave. I can get the two bluetooth module to pair up and communicate with one another using a serial communication in the Arduino IDE. Now what I want to do is to use a push pins to turn on and off an LEDs. Here is my set up for the loop and void set up. I attached also the code that I am using for the bluetooth.
=============================================================
void loop()
{
if(digitalRead(left_arrow_pin) == HIGH)
{
// seems like left arrow button was pressed
// so we clear all the pixels first
clear_all_pixels();

// and then we show the left arrow
left_arrow();
}
else if(digitalRead(right_arrow_pin) == HIGH)
{
// seems like right arrow button was pressed
// so we clear all the pixels first
clear_all_pixels();

// and then we show the right arrow
right_arrow();
}

else if(digitalRead(stop_sign_pin) == HIGH)
{
// seems like stop sign button was pressed
// so we clear all the pixels first
clear_all_pixels();

// and then we show the stop sign
stop_sign();
}
}
====================================================================
void setup()
{
//setting the button pins we defined above as inputs
pinMode(left_arrow_pin, INPUT);
pinMode(right_arrow_pin, INPUT);
pinMode(stop_sign_pin, INPUT);

//initializing the led strip
strip.begin();
strip.show();
}
