I’m closing of this project as I think that with the current configuration I will not be able to achieve what I want.
By closing this project I will kick of a new one(Version 2) which would be a bit more complicated from the hardware and programming point but at least it will give me more freedom. The new version of arduino automatic stairs is already being developed and I will post a new post soon(watch this space). For those of you who are still interested in this project here is a draft code:
int counter = 100; // for delayLights
// 8 LED pins
int ledPin11 = 11;
int ledPin10 = 10;
int ledPin9 = 9;
int ledPin8 = 8;
int ledPin7 = 7;
int ledPin6 = 6;
int ledPin5 = 5;
int ledPin3 = 3;
int ledVal;
float sinVal;
boolean nightMode = false;
boolean testRun = false;
boolean goingUp = false;
boolean lightsOn = false;
// choose input pin (for Infrared sensor UP)
int inputPin2 = 2;
int valUP = 0;
int lightSens = 0; //light sensor value
// choose input pin (for Infrared sensor DOWN)
int inputPin4 = 4;
int valDOWN = 0;
int ledPins[] = { 3, 5, 6, 7, 8, 9, 10, 11};
