Currently I am working on a project for controlling an Arduino Using an Android Phone. I was going to start with the project at the link below and go from there but I am having a few issues.http://forum.arduino.cc/index.php/topic,148853.msg1118346.html#msg1118346
I uploaded the app onto my phone and using an FDTI from spark fun I loaded the program on an Arduino Pro Mini 3.3V. I attached a 220 ohm resistor and an LED going from Pin 7 to ground. I checked to make sure the correct side of the LED was connected to ground. The power supply I am using is two AAA batteries and is connected to the RAW and GND. The BlueSmirf Silver Modem is connected to the Arduino with TX to RX, RX to TX, VCC to VCC and GND to GND.
When I first turn on power the LED on the BlueSmirf blinks red, I then connect the phone (Droid X) to the BlueSmirf and the light turns to green. But when I try to run the program nothing happens. If anyone has run into this before or has any advice on what to check I would appreciate it.
