help me in the programming!

Hi, I have a project to do with Arduino. I need a circuit that: - If I press a button to activate a digital output for a period of 0.5 to 20 seconds adjustable with a potentiometer. - Between the time when the button is pressed and the moment in which the output is enabled must pass a second. - Measure an analog value and present it to me on a display. - Measure the temperature and if it exceeds a certain value off the digital output even if the button is pressed. can you help me to make the circuit? thanks and sorry if my english is not correct :)

Have you any experience with Arduino at all?- have you at least tried the tutorials?

And as far as your project goes, let us know what circuit and code you have tried so far......

I already know the basics of C + + programming, but this project is more difficult than the ones I've done so far ... I need help in the code ...

But do you know C a la Arduino? Have you done some of the tutorials?

Asking for help is good, since it isn't the same as asking for someone to do it for you, so post what you have so far, even if it's faulty. Even post pseudo code if you like, because at least that means we can help with the logic....

can you help me to make the circuit

Your circuit will basically include an LCD, a button and a temp sensor on top of Arduino. Google for "connect LCD to Arduino", "connect temperature sensor to Arduino". You will certainly find hundreds of examples and source code. Then adapt the code to your particular circuit (pin-wise) and project specs.

To me, the circuit means the design of the electrical connections between the Arduino and your eternal hardware devices. Is that what you mean? If so, you will need to consider each hardware device separately. Usually, devices that are marketed for use with Arduinos will come with circuit diagrams and software examples showing how to use them with an Arduino.
