ALEGRO, JHOANNE KRIS P. and RIVERA, LEVINIA B. Android-based Major, Minor and 7 Ukulele Chords Trainer. Undergraduate Design Project. Bachelor of Science in Electronics Engineering. Cavite State University, Indang, Cavite. July 2017. Adviser: Engr. Edwin R. Arboleda.
The study was conducted from January to July 2017 at Cavite State University, Indang, Cavite to develop a microcontroller based Ukulele Chords Trainer. Specifically, it aimed to: design and construct the hardware unit of ukulele chords trainer; construct the system’s circuit layout; develop software to control lights from the device; provide an application software for the Android device; test and evaluate the performance of the system through pilot testing; and; conduct the cost computation.
The Ukulele chords trainer is a design project consisting of the ukulele itself, where LEDs were embedded in the first 4 fret of the fretboard; LCD and keypad shield and: the microcontroller. The device provides an android application software called “U-can-lele” which covers 3 modes: Play, Practice and Tuner. The device can function without the android application through the use of LCD and keypad shield but covers only 2 modes: Play and Practice. The light emitted by the LEDs serves as the guide for the user in fretting a chord correctly. Stand test option is included in both UI to check the connection of the LEDs. The system is run by the microcontroller, which was programmed in Arduino IDE.
Based on the result of the evaluation, the proposed system accomplished and met the given objective of the study. The user acceptance survey result proved that the device was easy to use, met it functions, application ran smoothly and worked properly according to the respondents’ experience to support this assumption.
The total cost of the design project was P8,083.00.
The unit was evaluated under a series of test for technical purpose before the user acceptance evaluation test. Based on the result of the evaluation the proposed system accomplished and met the given objective of the study. The user acceptance survey result proved that the device was easy to use, met it functions, application ran smoothly and worked properly according to the respondents’ experience to support this assumption.
Based on the result of the study, the authors recommended the following for the improvement of the project: 1. extending the scope of the chords of the device; 2. Wireless connection between the RGB LED and LCD interface; 3. install RGB LEDs to more than 4 frets and; 4. consider the use of sensors to pick up finger placing and checking. The total cost of the design project was P8,083.00.
