Description

In this project, we are going to make a Voice Modulator Circuit, by using self-designed PCB. This is a fun project, mainly designed for changing or altering the voice. Generally, when we speak in a MIC we hear same voice. But in this project, when we speak in MIC, we will hear a little bit different voice something like a robot is speaking. At the output, we have two choices for listening the modulated voice: speaker and 3.5 mm jack for headphone.

Here is the complete DIY tutorial to design this circuit and PCB
