justin1337

even when i put my hand in front of it.

and the servos work fine because i tested them and they go foward

when i navigate em the IR sensors don't work but the boe bot keeps going in the formation its programmed to do but when it reaches a wall or black tape it does not read it.

i tried rewiring it

i changed basic stamp chip

i changed mother board


what i do

you guys are the pro's

Hi Justin,

Have you tried running the program TestIrPairsAndIncidactors.bs2 from Chapter 7, Activity 4 in Robotics with the Boe-Bot?

This activity demonstrates how to wire LEDs to light up when the IR detector detects an object. It also displays the state of the IR detector so you can be sure they're working properly before attempting navigation with infrared headlights.

If you did run this program and everything is working properly, please post your code as an attachment and we can see if something is wrong there.

Hope this helps.

Jessica

Hi Justin,
In your code, it seems that you have both IN9 and IN0 set to irDetectRight, which is why the right one always responds, since the variable irDetectLeft is never set to anything.· Your code should read:

FREQOUT 8, 1, 38500
irDetectLeft = IN9
 
FREQOUT 2, 1, 38500
irDetectRight = IN0

Instead, you have:

FREQOUT 8, 1, 38500
irDetectRight = IN9
 
FREQOUT 2, 1, 38500
irDetectRight = IN0

After that change, everything should work!

Jessica
