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

is there a programming error?

Code:

'variable definitions
mid var word
left var word
right var word
right_detect var word
left_detect var word
middle_detect var word


left = -1000
mid = 1500
right = 1000



low p0

sound 9,[100\880, 100\988,100\1046,100\1175]         

pause 1000                          'wait one second

main:
 
 gosub a2d_check                          'get the IR information
   
    left_detect = left_detect/10       
  right_detect = right_detect/10
  middle_detect = middle_detect/10
 
 left=(left - 5) min 1325
 right=(right - 5) min 1325
 
 mid =(mid - 5) min 1425
 
 left = (left + left_detect) max 1725
 right = (right + right_detect) max 1725
 mid = (mid + middle_detect) max 1525
 
 if mid <15 then skip
  left =  (left - middle_detect) max 1325
  right = (right - middle_detect) max 1325
skip:
servo 0,left          'turn sensor left
servo 0,mid         'turn sensor right
servo 0,right          'return to middle position
pause 20

a2d_check:
adin ax2,0,AD_RON, right_detect
adin ax2,0,AD_RON,middle_detect
adin ax2,0,AD_RON,left_detect
return
goto main

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.

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

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.

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