Parameters

We needed to use an Android phone and make sure we connected to the correct Bluetooth device.

Evaluation & Discussion

Initially, we had trouble connecting the app to our Arduino. We were using a faulty Bluetooth module but we replaced it and then we were able to connect.

Conclusion

Most of our time was spent trying to connect using Bluetooth, but we were able to control the LED.
