Final Project Result

2013. 12. 3.

Final Project_Experiment Failed

Final Project Experiment
- Arduino (Control Arduino)
- Processing (Application)

Experiment 1
- Used Arduino & Processing
- The Bluetooth module (HC-06) didn't connect to any of two programs

Experiment 2
- Arduino & MIT app inventor program
- MIT app inventor program and Arduino didn't not connected.
- When it connected, the application didn't work.

Experiment 3
- Arduino & ArduDroid Application
- ArduDroid Application worked fine but the LED didn't work

Conclusion
- Need to fix the code
- figure out how to connect between application and Arduino code. The Bluetooth connection had no problems of connecting.
- Need to have 2k
