Android-Controlled Led Pyramind Using Bluetooth Protocol

The Android-Controllcd LED Pyramid consists of a LED-based three-dimensional light display controlled by the Arduino Platform with the assistance of an Android device and the help of a Bluetooth Module together with the Application Inventor. The study is capable of programming and storing multiple display effects and directing it with the use of an Android device. It used the Arduino IDE, installed Shift Register 7411C595, and the Bluetooth protocol to perform its commands. These commands were sent to the shift registers to control the states of each LED in the pyramid. Systematical direction generated display effects. An application in the Android device was invented to administer the implementation of the visual effects of the study. The LED Pyramid was developed through different experimentation processes like unit, integration, and system tests Unit tests were evaluated to assure the practicality of the LEDS and other components like the MOSFETS, Photocouplers, Transistors, Shift registers, Bluetooth module, and Android app. The integrated tests were conducted to confirm that the software and hardware components complement each other through the conduction and implementation of its functions. System tests were also performed to monitor the longevity of the system through the test of time. With the presence of all of these, the LED pyramid with Android controls and aesthetic effects was successfully established.
