In my post from last week I worked on creating a split lapse timer app (last week’s post). But later on when I was playing with the application I noticed that I naturally would like to have means to start or stop the timer.
Well this week I am implementing exactly this functionality.
The first thing I thought about was how to implement state in my app because a timer clearly has two distinct states either running or not running. That got me thinking about combining signals, mapping, you know, all the good stuff.
If you want to follow along you can download the starter project I prepared. It is in the shape where last weeks blog posts leaves off but I’ve added a couple of buttons in the user interface:

Now let’s put all those buttons to work!
