Hey guys,
I wonder is there is a topic about how to set up a sensor (LDR or IR).
I want to make one myself. Just to try it out.
I searched ont the forum but couldn’t find anything.
Thanx!
Read the sticky posts…
This one is for example code for sensors and sounds…
Also if were saying you want to try to create your own IR sensor, you might try looking at this thread:
lynxmotion.net/phpbb/viewtopic.php?t=5036&highlight=ir
Thanx a lot!
so now i made this fantastic sensor…
What code to use??
I have been looking here:
lynxmotion.net/viewtopic.php?p=46797#46797
But there are so many…
Help please…
UPDATE*
I found this code:
[code]’ ----- Program Description ]---------------------------------------------

’ This program demonstrates how to read the Sharp GP2D12 infrared analog output
’ detector with an Atom module and display the results in a terminal window.
’ Hardware Connections:
’ Atom Module Sharp Sensor

’ P16 Pin 1

'----- Variables ]------------------------------------------------------------
scanrange var word ’ A/D result variable
floating var float ’ Floating point math result storage
val var byte ’ Table conversion result storage

'---- Main Loop ] -----------------------------------------------------------
main
adin P4,scanrange ’ Read sensor value
if scanrange > 512 then ’ Test for obstacle to close to detector
serout s_out,I9600,“Too Close To Measure”, 13] ’ Send “Too Close” message
else
floating = tofloat( scanrange) / 5.12 ’ Limit value to <200 values
val = scantable(toint floating) ’ Convert A/D to measurement
debug [REAL floating," “,DEC val,13] ’ Output result to debug window
serout S_OUT,i9600,[REAL floating\2,” - “,DEC val,” cm",13]
endif ’ End If-Then-Else command
goto main ’ Loop back and get another reading[/code]
But it only gives me this output in the terminal:
0.00 - 80 cm
0.00 - 80 cm
0.00 - 80 cm
0.00 - 80 cm
0.00 - 80 cm
Am i doing something wrong?
I just ordered the gp2d12 at conrad.nl
hope that will solve these problems.
Thanx anyway!
