Help with IR sensor

i have just received my gp2d12 ir sensor
and i don’t know how to hook it up to the mini atom bot board
onto the analog I/O’s
for the basic atom :question: :question: :question:

Page 5 should help you out.

thank’s
but now the sensor isn’t responding
when i put my hand in front of it

is there a programming error?

Look at one of chunga’s threads on the IR sensor. He bought one a few weeks ago and posted some code he used I believe.

I’ve also written good code to handle the Sharp IR sensors as well as the IRPD.

where?

Go to my website and look for Rovers–>W.A.L.T.E.R.–>Software and download the latest version (bottom of the page).

is it for the gp2d12?
and if so, is it only for one?

Read the comments in the program. All the your questions are answered there. :smiley::smiley: I have comments on nearly every line of code or each major section and subroutine.

Huh, dunno…

oh well, im really having trouble finding working code for my GP2D12 thats all.

This program will make a sound that raises in pitch the closer you hold your hand to the sensor. The IR sensor would be plugged into the AX0 pin on the Bot Board.

irvariable var word loopit: adin 0, irvariable sound 9,[10\(ir * 10) goto loopit

16

when i compiled it it said theres and error on line 3?
i checked the spelling and its all correct.
(gosh i’m so unlucky today…lol)

17

Jim, in the sound line, ir needs to be irvariable…

18

like

but it still has an error on the (adin 0, irvariable)

Whoops I have been using the Pro so the syntax is a little different, set aside the typos…

irvariable var word loopit: adin ax0,1,ad_ron,irvariable sound 9,[10\(irvariable*10)] goto loopit

This works I tested it. :blush:
