Need Help Writing Code for watering system

[nuggetz21]

I am using an Arduino Mega with capacitive moisture sensor/ oled/keypad/peristaltic_water_pump/growth light. I am looking for the oled to display moisture level and also ask what moisture level to set. I'd like to be bale to use the keypad to input value for set moisture level. Then I want the pump to turn on if moisture level read by sensor is lower than the set moisture level. Independently of this I am looking to have growth light on for 14 hours and off for 10 hours. I am really new at this coding and I have tried some codes. they work separately but not together. Can someone help me?

they work separately but not together.

Probably because you use delay() for timing (I'm guessing cause you don't post the secret code) and your code blocks. Use millis() for timing instead.

Non-blocking timing tutorials:
Blink without delay().
Blink without delay detailed explanation
Beginner's guide to millis().
Several things at a time.

Please read the how to get the most from the forum post. The post contains information on what we need to know in order to help you and how to post code properly.

Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in a code block.

@groundFungus I believe I did use delay() - I will look again once I have the computer (where "my secret code" is) and post it here so I can get better input. Thanks for the info I will look into them!

@groundFungus this is the code I used - I removed some delays. It seems to be working but sensor reading is not steady.
