hello, i need help real quick. i’ve uploaded an arduino nano coding , it was successful but then it won’t run at all on my prototype. it was supposed to display “ set weight “ on the lcd so it can set weight and the water would be filled accordingly to the weight desired , by any chance , can you help me to fix this ?
For help, please read and follow the directions in the "How to get the best out of this forum" post, linked at the head of every forum category.

can you specify a bit more ? i’m new here
Hi @kaydaa, and welcome.
First, this isn't ER (Emergency Room)
Second, you're description needs clarification and your sketch (posted as code).
When does your exam, test, or lab class end - have you got 10 minutes left, or an hour?
i’m very sorry for the ER part , i was in rush as i have to bring the prototype with me today , you can say it’s a last minute error . i’ll post the code once i’ve reached my lab

i have time until tomorrow after a few discussions with my lecturer
Well, you've been told what to read(to be blunt, post #2 and 4, above) to help us help you, so...
Always show us a good schematic of your proposed circuit.
Show us a good image of your ‘actual’ wiring.
Give links to components.
In the Arduino IDE, use Ctrl T or CMD T to format your code then copy the complete sketch.
Use the < CODE / > icon from the ‘posting menu’ to attach the copied sketch.

Hi, @kaydaa
Welcome to the forum.
Can you please post your code?
Can we please have a circuit diagram?
An image of a hand drawn schematic will be fine, include ALL power supplies, component names and pin labels.
Can we please have some images of your project, so we can see your component layout?
What do you mean by "
Thanks.. Tom..
