Toggling a button in App Inventor

toggleApp Inventor is an easy piece of software  that starts you off in developing Android apps. If instead of two buttons to switch a state ON or OFF you want to have a button that toggles, the image shows how that is done.
Suppose I have a button called “bThuisToggle” it carries an image called “huis.png”. If I click it I want it to send a byte (85) and the next time I click it I want it to send another byte (117). I also want the image of the button to change into “huis_uit.png”.
The block in the picture shows clearly how to do that

    1. My pleasure. It is one of those things that once you know how you wonder why you hadnt thought of it before 🙂

  1. Thanks for pointing me to App Inventor. It is a fantastic environment to build simple things, prototype, and teach kids some technology.

    1. My pleasure. I have been digging in all sorts of tools that sometimes needed a gazillion bytes on my harddisk and were difficult to master. This is just an easy to master tool to quickly write apps
