Okay, so we won’t actually build a time machine in this chapter, but you’ll measure time by making a binary clock and a clock that can speak. We’ll also conduct an experiment to test how well your micro:bit can keep time. All the experiments and projects in this chapter use MicroPython only.
EXPERIMENT 9: KEEPING TIME
The aim of this experiment is to make a micro:bit clock that keeps good time. That means programming the micro:bit to tick at precisely one-second intervals.
One way to do this would be to use the sleep function, as ...
