This code emulates an OR logic gate.
/* Instructions
1. Upload the ISP sketch to an Arduino board.
2. Program the attiny accordingly.
3. Upload this sketch via Aruduino as ISP

//Arduino Emulating a Logic OR gate

//a faulty IC, or to improve on one..
//for example, No need to tie these pins down with pull up/down resistors
//add extra functionality of logic
void setup()

// put your setup code here, to run once:
pinMode(4,INPUT); // pin 3
pinMode(3,INPUT); //pin 2
pinMode(0,OUTPUT); //pin 5 (this is your Logic HIGH/LOW)

//add a delay for example
//delay(400);
