Hello Sir, Can i ask a Arduino uno can i used to for LDR and has an output of 0 to 5vdc

Hi, @mrayio800
Welcome to the forum.

Sorry, but you may have to explain clearer, the UNO does not have an analog output, it has a PWM output.
Where will the LDR be in the circuit?

Thanks.. Tom.. :smiley: :+1: :coffee: :australia:

Thank you for the reply sir, my project is refraction sir using the LDR i want to read the light passes using these LDR and an analog output value that i can insert to a digital display like autonics digital multi panel indicator 0 to 5vdc input.

I moved your topic to an appropriate forum category @mrayio800 .

In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

Hi, @mrayio800

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

Is this a school/college/university project?

Can you please post a simple diagram of how you would layout the LDRs and the media you will be measuring I assume will be angles.

Thanks.. Tom.. :smiley: :+1: :coffee: :australia:

That depends on which Uno. The Uno R4 seems to have a DAC on A0.

With a few additional components, yes.

As implied by @jim-p's comment, you can convert PWM to analog voltage using an RC circuit:
