Merry Christmas!

I am trying to make a stop watch that will create a lap time by hearing a sound over a certain decibel. Does anyone know if this is doable in thunkable?

Yes. You have to use clock(timer).

I can do this with buttons, i am wanting to use the microphone to trigger and record the time that it heard and sound.

Don’t think it can be done with decibel levels. But using speech to text, and detect the specific words like “stop” to trigger your app is possible.

That does work in the sense that it stops the timer but it takes time to process the word and would not make the time that it stops on accurate.
