Wireless Earphones To Bluetooth Speakers | DIY

Detailed step by step, written instructions: www.instructabl...
A year ago I had bought these bluetooth earphones (www.amazon.com...) from amazon for around $17. They were working just fine for the first 6 months when one of ear pieces stopped working. From then, they've just been lying around. While cleaning my room, I found these and decided to reuse the bluetooth receiver chip inside which was still working.
I came up with this idea of making a Bluetooth speaker with an addition of music reactive disco lights controlled via arduino.
So this project used a TDA7297 15W amplifier board along with a 10W speaker. You can even play music via aux. The bluetooth part also consists of voice calling, playback options, redialling, picking up phone or hanging up which were already present in the wireless earphones.
There are 4 RGB LEDs installed in the front, which change their color on every beat of music. There is a set threshold of the amplitude. The arduino takes audio signal as input. If it goes above the threshold, the color of the LED sets to a random one.
I used to hardwood to make the enclosure and 3x 18650 rechargeable lithium ion batteries to power the project. I haven't yet calculated the time for which the battery lasts.
It will take you almost 2 days to complete the project. This is also a budget build. How better can it be to listen to music on your homemade speakers!

I give you 4 out of 5 stars. First your lighting was EXCELLENT!!! Too many RUclips videos are extremely poor and difficult to view. YOUR LIGHTING WAS PERFECT.
There are many things I would have done differently, from your woodworking skills to the wiring. But, you did the best you knew how to do. When I was your age, I wasn't as skilled as you are now, however, I am 72 years old and have decades of experience in electronics and woodworking. BTW, I hardly ever give a 5 Star rating to anyone.
Bottom line: I love your little speaker! Keep up the excellent work and I look forward to seeing more videos from you.
Kind regards,

bro everything is awesome but at some steps you skip which wire to be connected with which part so we unable to make our. I need your help buddy plz mail me

[@SaiyamAgrawal]

Thank you!
Actually I tried to make the video shorter, otherwise it becomes boring and everyone just skips it. It's not easy to show each and every connection, out of so many via a recording. That's why I upload a schematic, link of which I leave in the description. You can even visit my instructables page: www.instructables.com/id/Wireless-Earphones-to-Bluetooth-Speakers/
