hello, I would like an orientation.
I saw several projects that integrate APP Inventor with Arduino,
unfortunately I only found projects where data from arduino sensors
are replicated on the mobile screen or actuators are turned on or off.
Would anyone know of an example where the mobile APP can pass a value
to an Arduino variable?
For example, turning on a lamp if the level of the photoresistor is
less than x, and the value of x is can be changed on the application
screen (typing the value or using a slider, etc.)
Any help is welcome
