In this circuit we are going to build a very Simple Intercom project using which you can communicate two ways locally within your house or school. This project brings in the childhood memory of using matchboxes with thread to build a simple telephone. So now let’s take it to the next level by building an electronic circuit (amplifier) to transmit voice from one end to another end.

Below are the components used in this project:
LM386 Audio Amplifier - https://quartzcomponents.com/products/lm386-low-voltage-audio-op-amp-ic
Speaker (2Nos) - https://quartzcomponents.com/products/speaker-0-5w-8-ohm
Microphone (2Nos) - https://quartzcomponents.com/products/small-electret-microphone-condenser-mic
Resistors (10k, 4.7k, 10k):
