I have problem with communicating VB.Net-Arduino. It seems the interrupt pause my serial communication line in void loop {}. I don't know what to do, and i can't erase interrupts line since i got this code from another site and he said that the interrupt play important role in his code. So, is there another method to keep interrupts like make a new void in the code? Could you help me, please?
here is the code:
//For MEGA 2560
int i=0;
int j=0;
int k=0;
int x=0;
int y=0;
int z=0;
int OK=0;
int OK1=0;
int OK2=0;
int OK3=0;
int OK4=0;
