I simulated a 10 second timer that counts down from 10 to 0. This is very simple to do. All you need to do is change the text property of the text value with a custom value and include a delay of 1 second. Then add a callback for the next number with a delay of 1 second. Repeat this until you get to the number 0. There is no need to use variables to simulate a timer.

An example of a date picker that can be imported and used in your project. (Basic use of variables) tags: calendar, picker, date picker

3 different counters using variables 1. A standard counter 2. A counter from the number of seconds the user sets 3. A countdown
