Bluetooth-FM-Phone Headset

A few months ago I wanted to make a remote-controlled relay can be controlled by SMS and Bluetooth, so I bought a SIM800H module but the GSM part of the module does not work fine and made me buy another module. The first module was on my table for months until I accidentally found an old headphone with torn wires and thought of making a Bluetooth headphone to use these waste parts. I took a Li-Po battery from an old mini quadcopter. I just needed a few parts, so this project has been started. The final product has the following features: A Bluetooth headset to listen to music and answer the phone calls; An FM radio capable of receiving 87.5-108MHz frequencies; A mobile phone to receive voice calls; A wired stereo headphone using an AUX cable. Making such a useful device of waste parts is really interesting and pleasant; I advise you to make one yourself by following the below link.
