Arduino Based Radio-Controlled Basketball Shot Clock

Presented in this study is a development of Arduino based radio-controlled basketball shot clock. Basketball, belng tha most played sport in the country, is a big factor in a person's life. Filipinos are known for being huge basketball fans, and the Philippines is said to be a basketball loving country. Basketball is a spox umposed of two teams, competing in a given span of time. A winner is declared based on which team scored more points in the alloted time. The shot clock, game clock and scoreboard are big factors of this game. The shot clock is the one responsible for controlling the pace of the game; it provides the time limit for a team to have one possession. The shot clock is reset whenever the ball touches the rim of the ring, whether a made shot or not. Professional basketball leagues allows a team to have a 24-second shot clock, while some collegiate leagues use 30-second shot clocks. This study aims to develop a standard sized seven-segment displays which will act as the monitor of this basketball shot clock. Also will be developed is the control panel which will serve as the master control of the hardware. The mode of communication is via radio frequency. The module used is nrf24i01, nrf24l01 is a radio frequency module which has a range of 10o0meters for the high-powered radio frequency which is used as the transmitter, and a range of 300meters for the low-powered radio frequency module which is used as the receiver. Arduino is the used platform, it is an open-source platform which is used in most electronic projects, since Arduino is an open-source platform, and it is initially empty yet a programmable one. Thus, Arduino is flexible and it can be used in this project provided a program that will run the specific objective. Also developed in this study is the power supply, this project demands specific power for each specific component. The seven-segment displays requires 12V, the Arduino demands a supply of 5V and the nrf24l01 requires 3.3V. Also, the control panel requires a 9V battery to operate which is commercially available. Various experiments are done to test the accuracy and precision of both the control panel and the monitor. Experiments involving distance were made to test the claim9 Of the nrf24l01 regarding the range of the module. Results shows astonishing data as it concludes nrf24l01 provides delay-less wireless communication even in a long distance. The maximum distance tested was 300 meters, which is far from the needed distance to operate the basketball Shot clock which is only at least 15 meters. Thus, the output produced is reliable, commercially competitive and can be used in any basketball games provided kat basic knowledge about basketball rules are being oriented to the operators before the game.
