New findings, I tried the dimmerLEB code and tried shorting the pins directly, I do get an output(-1).





Not sure whether this serves any purpose, but other than the "dimmerLED" code, the other 3 codes does not provide an output even with the pin directly shorted.

The site you linked to describes it as a 5V device and the diagrams clearly show a UNO being used, but the sample code refers to a 3.3V Arduino Pro Mini. I wonder whether the supply voltage requirements have changed, and what the actual voltage requirement for your board is?

Finally I am getting output now, HazardMinds was right, the A4 and A5 should swap. Took me much time to resolve this minor mistake. -.-"

Really appreciate all the help given!

Btw, for the touchpad, I am able to get reading of the X - Y coordinates as output.

If I wish to use it as a mouse pad, to control the computer mouse, how do I go about doing that so that the computer detect the arduino as a mouse peripheral .

Can Uno perform the above function? It is not listed inside

No, only leo, due and micro as stated.

Strange. Maybe their diagram is wrong. You did it by the diagram but still after swapping scl sda you go data? Anyway, good for you.

Yup, I swapped the SCL and SDA, it was later confirmed by seller too. They are going to update the wiki page soon.

Thanks for suggestion!

Now I am thinking how to implement USB-HID to use as mouse.
I would need to come out with a bigger sensor board with multi touch gesture function.
