The nature of badminton games is fast, agile, having a high intensity, and requiring full concentration. In the aspect of
physical conditions, including the agility, reaction, and quickness, a technological development of a training device to support
and to improve the performance required by the nature of badminton game is needed. This study was aimed at developing a WiFi
module based training device prototype for agility, reaction, and coordination for badminton. The WiFi module based device for
agility training was developed with wireless technology. This training device consists of four slaves; the placement of each LED
slave depends on the needs of the user. The suite of the slave involves sensors, a WiFi module, an LED RGB, and a buzzer. The
function of a sensor is to detect objects around the sensor range. LED RGB has a function as a sign when a sensor receives
stimulation. Furthermore, another device developed in this research was an application published in Play Store that can be
downloaded for free. This application was created as an effort to facilitate the user to move the lamp signal randomly according
to the needs. The name of the application is “Agility LED Control” from the Warriorrnux application system
