Voice changer with wave shield without keypad

[polpolpol]

Good morning,

I bought the kit to try voice changer (Adafruit wave shield, Electret microphone amplifier, potentiometer and speakers).
I connected the circuit as shown in figure (https://learn.adafruit.com/assets/2211) without the keypad but I use Arduino Nano v3.

It is possible to get the sketch for voice-changer in real time without the keypad?

Thank you!

The sketch does not require the keypad to be attached to operate n voice changer mode. You should be able to use it as-is.
