The thing you're measuring here is called the flicker fusion threshold--essentially the transition point between seeing on/off/on/off and a solid light--and is a little different from latency. Latency would be more like the delay between the LED turning on/off and your perception of that change. That delay is at least 100ms, and often a bit longer, though it depends on a lot of factors.
- majewsky 9y agoIf you want to test latency perception with an LED, here's what you would do: 1. Connect an LED and a button to the Arduino. 2. Program the Arduino to have the LED flash when the button is pressed. 3. In the program, add a constant delay between the button press being registered and the LED flashing. Increase this delay until the LED starts flashing noticably after the button is pressed.
