DrGPIO is a really small tool to control your Raspberry PI GPIO port from your Android Device. It also works as a handy reference for the GPIO pins when used in "reference mode". Just install it and follow the instructions.
Before using this application you must install WebIOPi on your Raspberry. You will also need to have direct network access to your Raspberry PI from your Android device.
¡Warning! Here be dragons.... This is a "beta" version, if you find any bugs please report them.
