Wi-Fi Controlled Basketball Shot Clock

Shot clock is one of the implements used in the basketball game. It is used to display how much time a player has left to shoot the ball. The shot clock is administered in the game, consequently, to increase pace of the game by limiting length of time taken between shots which is, usually, 24 seconds. The researchers have developed a wireless basketball shot clock system through the implementation of nodemcu and Arduino microcontrollers. The former is used as the core component of the controller and the latter is used in the seven-segment displays. The controller and the displays communicate wirelessly through WIFI. ESP822 modules are integrated with the microcontrollers to append WIFI functionality. The nodemcu board already has ESP-he module integrated with its system. The Arduino board, on the other hand, is wired with ESP-01 module. The hardware components are chosen to achieve the objectives of the study, and to bring up several significances. The controller is developed to dispatch command data in accordance with button events to the displays. The displays must be able to receive the transmitted data without delay, and one must operate in synchronicity with the other. Two tests are used to determine whether the objectives are satisfied. The Data Accuracy Test revealed that the controller is able to send the command data to the displays. Hence, the data transmission and reception of the system is fairly reliable. On the other hand, the range test revealed that the two displays developed are able to receive the command data at the same time when emplaced on an actual basketball court. Hence, the system components operate in synchronicity.
