MPR121 and Arduino(5v)

Development Boards Arduino

Hi,

I was looking for some help with connecting up my MPR121 Capacitive Touch Sensor Breakout Board http://www.sparkfun.com/products/9695 to my TwentyTen board. I was looking at this tutorial http://www.sparkfun.com/tutorials/65 would the 3rd diagram using diodes be the easiest way to set this up?

and if so would a 1n4004 diode be suitable? Voltage drop from it is about 0.3v if I am correct

Yes, no, maybe

Try it and hope stuff doesn’t blow up…
