Bluetooth module for PS3 control of a 3D printer

I have given up on using a PS3 controller with the Arduino boards, I think that someone will be able to do it, but I don't have the time as I am studying for my A-levels.

I did however come across this video which showed Bluetooth connectivity between a 3D printer and a computer instead of using a cable.

I might try this at some later date.

I2C UNO and MEGA for RepRap Prusa i2 control using PS3 controller.

For the last couple of weeks I have been trying to connect a PS3 controller to my i2 however it hasn't been going as well as I though it would.

I thought that using an UNO with the USB Host Shield would be able to communicate with the Mega through I2C and then send G-code to the printer when buttons are pressed on the controller. 

However I am unable to get I2C communication at all, I have tried a few tutorials to no avail, I can get basic sketches to work with the Uno and Mega without Ramps 1.4 attached, but when I but the Ramps board on and use the I2C pins on that, nothing happens.

I have tried setting the Uno slave and Mega Master and vise versa but this still doesn't help.

If anyone has any ideas please leave a comment.

PS3 controlling RepRap Prusa i2 using UNO and I2C

I am still trying to connect my i2 to a PS3 controller and this time, instead of using the mega to attach the USB host Shield to, I will try to use and Arduino Uno instead and send which buttons are pressed to the mega through the I2C.

This way I avoid having to use the Mega's inaccessible ICSP pins.

If this doesn't work i may try doing it through Bluetooth.
