If the garage door opener already has receiver for remote control, you can buy a kit that has new remote control and new receiver. You replace the old receiver with new one.

I don't think it's good idea to pet the cat while working on Arduino project.

I think that the charger is for power wheelchairs.

Searching ............
ERROR: Bluetooth Module not responding!
Make sure there are no active bluetooth connection and try again

I think you forgot to connect ground to the Arduino Micro.

Please send me the sketch that for checking and setting Bluetooth baud rate. I added

Serial.println("***");

as the last line of setup() and the stars show up on the serial monitor.

I think that version 2.3 works but I don't see anything on the Serial Monitor after changing #define DEBUG from false to true. I can connect my tablet to the Arduino UNO board with Bluetooth module but the Pin 13 LED doesn't work when I touch the buttons next to the "joystick". The values change when I move the "joystick". The LEDs on the Bluetooth module changed from flashing red to non-flashing green.

I can't find the hardware menu button at the bottom of the tablet screen. When I move the joystick, the X and Y values at the bottom left corner of the screen change. A red message at that corner says "Not Connected".

The screen shown on the second screenshot at https://play.google.com/store/apps/details?id=org.projectproto.btjoystick&feature=search_result#?t=W251bGwsMSwxLDEsIm9yZy5wcm9qZWN0cHJvdG8uYnRqb3lzdGljayJd doesn't show up. How can I fix this?

I have Samsung Galaxy Tab 7" tablet and Arduino Uno. The X and Y values on the tablet screen don't display the position of the joystick and nothing is displayed on the serial monitor. How can I fix the problem?

Try a parallel port card like the one at http://www.newegg.com/Product/ProductList.aspx?N=100007531%20600022012&IsNodeId=1&Submit=ENE
15  Using Arduino / Motors, Mechanics, and Power / 3.6V cell phone batteries as power source for Arduino projects? on: June 22, 2013, 01:55:57 pm
Radio Shack has 3.6V cell phone batteries in stock. Is it possible to use them as power source for Arduino projects? If so, how can I charge them?
