arduino IR sharp 2Y0A21 (SOLVED)
August 8, 2011
i.ve been googling and searching around for ages now but cant find why my sharp ir sensor gives a standerd return of 300 in the display of serial monitor..
when i put my hand in front it wil display a number based on the distance of my hand between an int of 200 to 600 and sometimes a little more..
do u guys know how this can be happening. because my arduino now thinks he's seeing an object and returns 300 while in real life my arduino is facing notin but air..
