My name is Peter from the Netherlands and I'm new on this forum.
I recently bought an Arduino Uno with an Ethernet Shield.
Now I try to understand how it works by a to use variety of programs examples from existing projects.
I am very interested in communication between the Arduino and my Android.
Recently I've made something so I can switch an output on the arduino board by using my android
I used App Inventor to create an App for this.
Now I'm trying to create a feedback signal from a digital input from the arduino board to my android.
I understand that I have to use the "TinyWebDB1.GotValue" but I don't know how and .
I need a working example with 1 digital input for my arduino and for my App Inventor please.
In the app I have one button to switch an output and one label that indicates the status of the input (red/green for example)
Can anyone help me with this problem ?
(With this message I attached the project code from the app and a screen print)
