Today I made a Bluetooth amplifier in a very compact size.I used a few components to make this Bluetooth amplifier.For example, a Bluetooth module, an audio board, a battery for power, and finally a solar panel, which will charge our battery.This project of mine is very small in size but very beautiful and the powerful amplifier gives very nice sound output.We can connect our phone to this amplifier and play that song through the phone. #diy #audio #schoolproject
