MP3 Sound activated by many LDR modules with Aduino Uno

Projects General Guidance

Hello this is just my second project, sorry if is basic for you.

The objetive is to use four ldr modules like this one: https://www.eprolabs.com/product/ldr-sensor-module/

I'm working with Arduino ONE and I want to know if I can use the 5v pin of the card for all the modules, every sensor will be exposed to a light (those lighst aren't part of the same circuit). When something covers the light I want to activate a mp3 sound(I want use my computer to play the sound).

I have no problems with programing, the main problem is that I don't know if the card can handle those 4 modules at the time. If that is not the case I accept any suggestion.

Thank you for your time and help!!!

Not a problem to power four of those modules from the 5volt pin.
Connect all grounds to Arduino ground.
Connect all 5volt pins to Arduino's 5volt pin.
Connect the four digital outputs to four digital inputs on the Arduino (not pin 0, 1, or 13).
