relais - sensor - arduino - light - PROBLEM !!!

hey guys!

i'm doing a light installation with neon for an exhibition. sadly i've got a problem with my infrared sensor. maybe u can help my.

i've got 18 neons and they are combined to 6 groups. the relaises are set that they controll my neons (on/off). now my infrared sensor (also 6) should control my relais. sadly something went wrong with my circuit (or my code), because electricity reflows and manipulate my measured values of my sensor.

do you have any idea why this is so?

thx a lot, yours, vorwind.

Well let me see? Do I know what you actually did? No, with no schematic or code posted how on earth is anyone supposed to know how you screwed up.
