Hi

I'm reading rpm in a TFT display. Is it possible to send the digits to a cell phone via bluetoorh instead?

Thanks

The short answer is yes. The magic line of code is
Serial.print(dadedah);

That depends.
Is that TFT display controlled by an Arduino?

Yes.

Then, yes, with a Bluetooth module. There are then plenty of Arduino/BT apps in the app store. It gets a little more complicated if you want to store or do stuff with that data. But get there, first.
