This project consists of making a widget that displays the battery percentage of an android phone in a progressbar and changes color, depending on the percentage. The progress bar should turn green from 80 to 100%, yellow from 60 to 79% orange from 30 to 59% and red from 0 to 29.
The widget should be able to connect with an arduino board with a bluetooth module.
The widget should have a button named bluetooth, so that the user can connect to
nearby bluetooth devices, and the bluetooth adapter in the phone should turn on,
when the battery reaches 87%, then it should send a signal to an arduino that will be connected to the app through bluetooth, to turn on a LED, when the battery reaches 85% and then turn off the Bluetooth adapter on the phone.
When the battery reaches 97% the bluetooth adapter on the phone should turn on and then send a signal to turn off the LED when the battery reaches 99% and then turn off the bluetooth adapter.
A Video showing the app turning on and off a LED connected to an arduino should be uploaded to verify that the app works.
Before placing a Bid, you must agree that the ownership of the final output will be mine.
The app for the arduino will be left in the uploads section.
