ok, so I'm trying to set up what started out to be a simple code to turn some LED lights on up the drive in sequence.
Then I wanted an exit sequence.
Then I though adding Ultrasonic system to start the lights automatically when someone entered the drive...
After that I decided a PIR would be better suited for the job..
Which I have placed inside a PIR based Cat/animal scare unit.. so looks like original, but will trigger lights
but I cant seem to get the coding quite right.....
it will probably appear messy, as its been changed sooooo many times....
I'm using a 8 way relay block, and just an Uno board, 16x2 LCD display for info inside the house..
it seems to sit and just detect things all the time, or as seems fit enter the exit mode sequence
code is below..
#include "LiquidCrystal.h"
LiquidCrystal lcd(A5, A4, A3, A2, A1, A0);
#define RELAY_ON 0
#define RELAY_OFF 1
#define Buzzer 2 //output to buzzer +'ve
#define PIRin 3 //from PIR sensor
#define Switch 4 //switch to reverse trigger LED's for exit
// #define Turnon 1 //switch LED's on until switched off
#define RELAY1 5 //relay for LED light section 1 by post
#define RELAY2 6 //relay for LED light section 2
#define RELAY3 7 //relay for LED light section 3
#define RELAY4 8 //relay for LED light section 4
#define RELAY5 9 //relay for LED light section 5
#define RELAY6 10 //relay for LED light section 6
#define RELAY7 11 //relay for LED light section 7 step 1
#define RELAY8 12 //relay for LED light section 8 step 2
#define Led 13 //LED to indicate outside lights triggereed
