I have tried to make a program using "struct" for 6 button state and one angle input signal to control using 6 LEDs and one Servo and its working fine(Program mentioned below.) But problem is that when i add two more input signal that time output become erratic and output is not getting as per program.Please help to modify the program. transmitter

Problem while connecting two arduino with NRF24L01

I am a beginner in Arduino programming so that program is also little bit lengthy sorry for inconvenience. I have make a program for wire less controlling of a servo motor and LED(7 Nos.) using ARDUINO UNO, Funduino Joy stick shield V1.A and NRF24L01.First i have prepare the program (using Array) only for controlling the LEDs and its become success as that LEDs working as per program.Than i added Servo motor also in circuit and make some changes in existing LED program. Unfortunately the result is erratic out put.joy stick input signal interrupting the led signal and some time servo motor respond led input .Transmitting code and Reciever code given below.

I came to know that this problem will solve using "struct" command in existing program . Please help me to modify the program with "struct".Because i have no thorough knowledge in C,C++
