Problem with simulation

Did you have a question you wanted to ask about that picture?

Please post your schematic as an image and not a screenshot. Screenshots are so hard to read.

[sbahlerh_andy]

Yes
I want a correct connection
Its says its wrong

[Delta_G]

Do you think you should maybe provide some information or do you want people to have to guess at what you are trying to build?

You will find that the level of help you get will be directly proportional to the amount of effort you are willing to put in when presenting the problem. If you cant be bothered to write a few words then you wont get much help.

I am building a mini HVAC system for mobile applications using the following components:
Arduino
Temperature sensor LM35
Battery
Voltage regulator
Fan
Heater
LCD display 16x2
Relay
Switch and
Socket

What web site?

[andrewdonaldson177]

the green LED and Volt Meter was for the purpose of testing.

click the link to download the schematic.

chatGPT nonsense.

[sbahlerh_andy]

Can you please show me the schematic diagram of the circuit or connection

[jremington]

@andrewdonaldson177

Please respond instead to the OP's request in post #9 and post a proper schematic diagram. Hand drawn is fine, with pins, parts and connections clearly labeled.

chatGPT blather and the 30 seconds of your effort to produce, cut and paste it into a post is not welcome on this forum.

[Delta_G]

I would help out if OP could find the time to explain a little more than just a few words and a list of parts.

mini HVAC system

Could mean a lot of different things.

@sbahlerh_andy

Its says its wrong

Is this simulator Proteus ?
Did it say explicitly what was wrong, for example a floating R/W connection on the display?

Hi, @sbahlerh_andy

How to get the best out of this forum

See also FAQ - Arduino Forum for general rules on forum behavior and etiquette. Hello, Welcome to the Arduino Forum. This guide explains how to get the best out of this forum. Please read and follow the instructions below. Being new here you might think this is having rules for the sake of rules, but that is not the case. If you don’t follow the guidelines all that happens is there is a long exchange of posts while we try to get you to tell us what we need in order to help you, which is frus…

Can you please tell us your electronics, programming, arduino, hardware experience?

Thanks... Tom..

[sbahlerh_andy]

Please provide a schematic diagram using proteus simulation and without the breadboard

[andrewdonaldson177]

Sorry I don't have Proteus this is Tinkercad if I had your code I could have tested it further but I did verify it is properly functioning with the virtual volt meter.

Thank you

But i dont see clearly the components
Did you use the components i mentioned above
Arduino, temperature sensor, battery, voltage regulator, switch, LCD display, fan, heater, and socket. This is the schematic diagram i need using these components on the proteus simuation app

Do you have access to the Proteus app?

[sbahlerh_andy]

Yes i do

[xfpd]

How is Proteus indicating your wiring not working?

[sbahlerh_andy]

Its says Fatal simulation errors encountered
