Not clear?
I dont think my orginal explanation of this project was clear enough.
Digits come at intervals of 30 seconds. Total digits per input = 1. Total inputs per code = 4 So I need to scan for 2 minutes, then once I have all four digits, I need to send an output based on the input received.
Look for input1 for 30seconds = TS1
Look for input2 for 30seconds = TS2
Look for input3 for 30seconds = TS3
Look for input4 for 30seconds = TS4
so if I get a 1 as my first input, then the other 3 inputs dont matter, LED1 lights up.
If my first input is a 2 but the other inputs are all zero's, then no LED's light up
If my first input is a 2 and any other input is 1-4, then LED2 + LED1 light up
my examples of the first inputs being 2 correspond with the first inputs being 3 or 4 aswell.
Example of 5 different codes received and their output operation:
ts1---ts2---ts3---ts4
1-----0-----1-----0---= HIGH LED1
2-----0-----0-----0---= NO LED'S HIGH
2-----1-----0-----0---= HIGH LED1 and LED2
3-----0-----0-----0---= NO LED'S HIGH
3-----0-----2-----0---= HIGH LED1 and LED3
hopefully this will help clarify the operation. i've changed my code a bit, I "think" its starting to get to where it needs to be, but I still dont know how to assign 30seconds per input received.
