In this web I wrote many examples of App Inventor, Bluetooth and Arduino:

In this post I present extensions about 3, 4 and 9 Multitouch:

Now we join those two projects:

Android with 4 zones multitouch send order to Arduino by Bluetooth for ON/OFF 4 LEDs.

You can touch several zones at once and send information to Arduino by Bluetooth for ON/OFF 4 LEDs.

Hola amigos, en mis tutoriales de App Inventor puedes encontrar información sobre Arduino, App Inventor y Bluetooth, en esta ocasión he unido el proyecto de Bluetooth con la extensión de Multitouch que he indicado en el enlace anterior.
Puedes pulsar una o varias zonas a la vez y enviar información por Bluetooth al Arduino para encender y apagar 4 LEDs.

very beautiful
We can also turn the lights off by driving the relay.
If possible, help to speed up & down the control of the ac fan.
