Don's Electronic Thing part 3

I just received my HC-05 Bluetooth module!  Spent some time figuring out how to setup the circuit,

The fellow at this link has a nice simple setup that clearly shows how to hook up the BT module.

I did get it to pair with my android tablet (yea!).  Now I need to figure out the arduino coding to read it...


update:

   It does work!  I used a "chat" program in RFO Basic to send simple commands to the arduino, making a couple of Leds blink.  Next is to get the switch feed back to work.
