I'm trying to create a two-in-one capacitance and ohm meter .I am completely new to the ardiuno community and any insights would be helpful. Currently stuck on the circuit configuration, Ive put together both the ohm meter and capacitance meter separately however am having trouble combining the two together. I want to be able to insert an unknown capacitor or resistor in a pair of terminals and have it measure the value of the component. Thanks in advance for the help guys:)

SIMPLE TROUBLESHOOTING.
These steps may also save you some unnecessary time and effort in the forum.
- Always provide as much detail as possible to your issue it may be important.
- If applicable provide your SKETCH inside CODE TAGS ( </> ) or a CREATE share link.
- If applicable provide a schematic even if hand drawn.
- How to insert a picture into your post
COMMON ISSUES
-
Check you have a COMMON GROUND where required.
-
Where possible use USB 2.0 ports or a USB 2.0 POWERED HUB to rule out USB 3.0 issues.
-
Try other computers where possible.
-
Try other USB leads where possible.
-
You may not have the correct driver installed. CH340/341 or CP2102
-
There may be a problem with the board check your wiring first.
-
Remove any items connected to pins 0 and 1.
COMPUTER RELATED -
Ensure you turn off any additional security / antivirus just to test.
-
There may be a problem with the PC try RESTARTING it.
-
You may be selecting the wrong COM port.
-
Avoid cloud/network based installations where possible OR ensure your Network/Cloud software is RUNNING.
-
Clear your browsers CACHE.
-
Close the IDE before using any other serial programs.
-
Preferably install IDE's as ADMINISTRATOR or your OS equivalent
Performing the above actions may help resolve your problem without further help.

I want to be able to insert an unknown capacitor or resistor in a pair of terminals and have it measure the value of the component
so how would you do this normally, first for a resistor, i suppose you apply voltage to a voltage divider where one of the resistors has a known value, and one unknown and measure the voltage halfway, the minimum value of the known resistor should make sure the current does not exceed 40mA
For the capacitor applying voltage through a resistor and measure the time it takes to charge and discharge.
So if you already have the circuit, share it. If you already have some code, share it.
Try browsing for a arduino component checker. I found this as my first hit: https://www.instructables.com/id/Component-Tester-Test-Almost-Anything-/

If you do an instructable like that, ask yourself, am i up to the task of building it ?
And more importantly, Do i understand all of the code ? because there is not guarantee of support by the author.
