FM receiver kit and audio amplifier using LM386
This is one of the simplest ways of making an FM receiver. Just get a low cost FM receiver kit, make an audio amplifier using LM386, connect them together and your FM receiver is ready.
Most of the commercial FM receiver kits receive the signals within the FM band, usually 88-108 MHz.
This project is for novices who can make projects on breadboard.
If you have never made an Audio amplifier, please try this: LM386 on breadboard. The tutorial shows you all the connections.
The FM receiver kit usually comes with 4 wires: +6V, GND, Antenna and Audio. You need to connect the ‘Audio‘ wire to the ‘input’ pin of the audio amplifier circuit.

Can you please explain where and how we should connect the 4 wires in the FM receiver kit???
When you buy the kit, the seller should give you the instruction manual also. Usually, there are four wires, one should be red that is connected to +ve terminal of battery then second should be black that is connected to -ve, then third one is to be connected to the input of LM386 audio amplifier and the last is antenna wire which is not connected anywhere.
Thank you so much for your hard work, I’m going to make something similar for my school project, but I wanted to know is it possible to make my own FM receiver kit? or an FM transmitter and then connect it to this amplifier ? if so, how can I connect the two circuits together? Thank You
I don’t think it will be easy to an FM receiver, because you are just studying in school and making an FM transmitter won’t also be easy. I recommend you to buy FM receiver kit and make an audio amplifier yourself. While school, make simple and easy projects. If you start with difficult projects, you will soon quit electronics.
i want the same detail 4 making sound operating light wil u plz help me
Hmm is anyone else experiencing problems with the images on this blog loading?
I’m trying to find out if its a problem on my end or if it’s the blog.
Any suggestions would be greatly appreciated.
