After got the hits to work, we started with the first input are the LEDs. These LEDs are for the players lives, every time a player gets hit, each LED will switch off. Umar chose a design of a heart shape and have it placed on the chest. He came up with the idea as the player will understand what it is also it is visible to the players.
Each vest has 8 LEDs = 8 lives. Yellow vest has 2 green LEDs because we didn’t have enough red LEDs.
Solder it to the PCB board and added the resistors to the negative leg to each LED.
