Welcome to the forum
Why did you start a topic in the Uncategorised category of the forum when its description is
DO NOT CREATE TOPICS IN THIS CATEGORY
Your topic has been moved to the Programming category
Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'
Use code tags (the < CODE/ > icon above the compose window) to make it easier to read and copy for examination

sorry for the mistake i am new to this forum so thats why i made a mistake tried to edit the post pls let me know if it is ok?
Show your code that includes your attempt to store the pin states.
Looks OK now
1 Like
i surf the internet but found nothing all topics are with a push button which is unable to understand pls alter this code and help
perhaps you could exp0lain:
1: what you expect it to do and
2: what it is doing
it is turning on lights on movie interval but on device reset, it is not retaining pins previos state . so need some alteration in code to store its pins last state incase of reset/powerloss.......
following a reset (or power down) the arduino runs setup() - as its supposed to do.
And in setup you set all the lights high.
you need a storage location that retains data during power down.
Like this
or
Save the data each time the lights condition is required to change, and read the value when the system starts up.
You may need a button to set the condition that setup() presently provides.
As the eeprom has a limit (100,000) to the number of writes to a cell, so if that will be a problem you could alternatively use an external sd card
Your first link might not quite be applicable; as far as I understand from the topic title, it's and ESP8266.
But OP should have enough ammunition to start understanding what the options are.
Thanks @sterretje I linked to the wrong tab; I've added the one for the 8266
Anyway I prefer the sd card solution
I've just seen this which could be another alternative
