A simple countdown timer library for Python or MicroPython
Project description
Countdown Timer
This simple class allows you to simplify project that require a countdown timer. Simply set the duration of the timer either using countdowntimer.duration
or countdowntimer.duration_in_seconds
and then run countdowntimer.reset()
. It will then countdown from the future time - current_time + duration
. Once the timer is up the isalarm
variable will become True
. This can be put into a simple loop such as:
c = CountDownTimer()
c.duration = 1 # minute
c.reset()
while not c.isalarm():
c.status()
sleep(0.25)
print("Timer is done")
