[SOLVED] How can we change the state of 3 adjescent

[varunme]

when the adjescent sensor gets activated then the previous light not going to 50%,

is it due to the inverse logic created by using ULN2803 ?

and there is some lag created between one sensor and other sensor to activate,

I would suggest to look into your hardware for those problems, software is executed fast, I don't think the lag could observed because of the software.
As for 2803, I couldn't tell unless a schematic is provided. Generally the ULN2803 is a driver, and does not have latch capabilities. Only external circuitry could lead to behaviour like that.

yes,
I will check all hardware and revert back

Except the previous light off feature, all others are working,
thanks for such a nice support for me
