Answers (2) However there is no way to control arduino without delay. In particular the standard connection of serial over USB can be fired at most 1000 times per second and typically less. It is common for people to have difficulty exceeding 40 Hz unless they write custom code on the arduino side. In theory you might be able to achieve lower. Example: elapsed time. When you press button B on the microbit, this program finds the number of milliseconds since the program started and shows it on the LED screen. Edit JavaScript Python Run. running time (ms) now show number set now to on button B pressed.
