“A simple clock with a countdown timer function implemented with the Calliope mini 3 and some Grove modules.
A simple clock with a countdown timer function for the Calliope mini 3. I made this to experiment with the new Calliope mini 3, especially to check the new pin connector of the mini 3.
A description in German can be found on Gitlab. The MakeCode code is on Github.
The clock should work like this: to set the current time, Click button A on the Calliope mini board first, then set the time using the two Grove buttons (it is a 24h clock). Click button A again to finish. The 4 digit display will show the current time.
You can start the countdown timer as follows. Click button B on the Calliope mini board and set the timer (in minutes and seconds) with the two Grove buttons. Click button B again to start the timer. The 4 digit display will show the countdown timer. When the timer elapses, a short melody is played and then the clock is shown again.
