So I've been working on this for some time now, and am still struggling.
I am using codebender.cc, and I connected to the Serial Monitor from there.
Below the Serial Monitor, there is a textbox and a button that says "Send". Is this the computer sending data to the Arduino or the Arduino sending data to the computer/serial?
In any case, when I send a message from there, it triggers an event on my Android smartphone, which is connected to the Arduino by Bluetooth (the HC-06 module). So I suspected it was acting like the Arduino itself.
Also, if I need to send data from the Arduino on Bluetooth to an App, would I need to use Serial.println() or Serial.write()? I just need to send a bit - 1 or 0.
I would really appreciate any help. Thanks.
