Hello. I have an Elegoo and I was wondering if anyone knew if Elegoo Uno r3 boards have Analog to digital conversion. If not what do you think the best ADC converter would someone suggest. I want to record sound from a microphone hopefully I can afford an Arduino in the future. Thanks for any tips.
The ADS1115 is too slow for sound, and an Uno has not enough memory to store it anyway.

It has nothing to do with Elegoo. They simply make a version of the UNO. Anything which actually uses the UNO design (or a Nano which is a more practical version in the majority of cases) with an ATmega328 (or any Atmegaxx8 chip) therefore has an ADC.
As pointed out, this is not suitable for recording sound in any case. For that you need an actual sound recorder chip which may well be able to be controlled by an Arduino.
Information about using the microcontroller's internal ADC here:
As pointed out, not useful for your specific application, but still very useful for other applications.
