very simple circuit and the code is so simple , just using Arduino Nano with Bluetooth module and small buzzer with battery booster from 3.7v to 5v , and i have create an app in MIT App Inventor ,
* you can connect your remote to the same buttery and It will save you a lot of money you spend it on Non rechargeable batteries working on it to make it so small and very cheap , I'm thinking to use ATtiny85 .
