...video that will show you this as well I have developed a game called Word Wheel Challenge. It works by using a virtual spinner in the game. There are two major wireless buzzer companies. Company A is a lighted wireless buzzer company that wrote code into their keystroke software to make it spin with one click. Company B is a simpler wireless buzzer. They cannot write code into their buzzer hardware. Company B's buzzer has a high-speed latency of 8-12 ms. I have to hit that buzzer 2 to 4 times for it to make the spinner go. I don’t know if it’s a latency issue or something else. A separate company has a game that is simply a virtual wheel spinner and nothing else.
