Hello, Im some what new to arduino and have just messed with the very basic stuff. I have an idea for a project where I can turn LEDs on and off via Bluetooth from my android phone. I have a uno board and a bluetooth shield from seeed. How hard its this going to be to tackle?
From the Arduino perspective, its not that hard to tackle, since there are many examples of how to connect and establish connections between the board and a bluetooth device.
The complications may come when your actually programming the android application(assuming your creating an application from scratch). Since this takes a good amount of Java experience and some time.
My advice would be to look into already made applications on the PlayStore, such as ArduDroid by Hazim Bitar. This application will allow you to manually switch analog and digital values from your phone as long as the bluetooth is initialized. Thus will save you a lot of time and will make your project much easier to accomplish .
