I'm able to connect the 1018 with the IR Sharp but the device cannot detect the small resolution of mm
Ex: i have 20 pcs of card (thickness is 4mm). so I have 80mm is the height. I put the IR on top at 100mm away from the cards. If I remove 1 card the distance will be 104mm, 2 cards will be 108mm... and so on...
But the result is totally failed. How can I change the formula to make it work perfectly?
