If there are any safety issues associated with the "pusher", you may want "Stop" to be called when you release either the "Extend" or "Retract" buttons. You should be able to do this using the touch down and touch up events.

What do you want to connect to? You have a bluetooth block there so I assume you want to connect it to either an arduino via bluetooth module or an ESP****. It would be good to know. Anyway, you can find BT examples in @Juan_Antonio 's and some other tutorials.
The codes below are for Bluetooth Classic using HC-05 or ESP32.
In your Arduino code often you need to set certain I/O to a specific state, depending on the Bluetooth connection status.
This can be done in many ways, here is the way I do it:
If you are using HC-05, you can do it like this:
[hc05]
Define a I/O pin to monitor the connection status: const int BtStatus = 2;
Set the BtStatus pin to: pinMode (BtStatus, INPUT);
Connect the STATE pin from the HC-05 to BtStatus pin.
Monitor the c…
Hello friends,
in this tutorial Martyn Currey manages to use a Bluetooth HM-10 (BLE) in stand-alone mode, that is, without Arduino or any other device, to turn on/off an LED.

I have tried it with a Bluetooth HC-05, but I have not succeeded.
For it to work for me I had to accompany the HC-05 with an HC06. Here is my experience.
