Salam alaikum (peace upon you)
Could I have any help in that project?

Build a digital Avometer using Arduino.
• The device should be able to measure the following:
1. Voltage range [ -9 V, 9 V ].
2. Current Range [ -0.5 A – 0.5 A].
3. Resistance Range [ 50 Ω – 100 kΩ].
4. Can detect voltage and current frequencies up to 500 Hz only “Greater frequencies should be attenuated by 3rd order filter”.

Device sensitivity in each measurement mode should be calculated.

Even more;

Resistance range [10 Ω – 100 MΩ].
• Connectivity Test Feature.
• Measure the frequency of the input voltage and current signal.

Mainly, I have two problems
1) how to do the idea?
2) the circuit collapse after connecting

Wouldn't it be a Megger now?

What have you tried so far? There are Arduino projects on the internet that explain how to make all of those measurements. Try them, one at a time and then combine them into one program, selecting the function with switches.
