batteries whenever the motors pull power and sunlight coming from the windows.
If we inspect the output when the sensor is over the white table (highlighted in blue), the readings jump around
~632 to ~813
. This is a bit bigger than what we initially read. If we inspect the output when the sensor is over the
brown cardboard surface (highlighted in green), the readings jump around between
~60 to ~650
. This is bigger
than what we initially read. One reason for this is that the brown cardboard is not uniform throughout the material.
Additionally, the distance between the line following sensor and cardboard became the same as when it was
driving over the white table. If we inspect the output when the sensor is over black electrical tape (highlighted in
red), the readings jump around
~932 to ~988
. This is a bit bigger than what we initially read with the white table
but not as big as the brown cardboard surface.
Note:
The distance between the line following sensor and the surface matters! Make sure that your surface is
flat and the wheels are on the surface that it is traveling on. Any deformities on the surface can affect the line
following sensor readings. Remember to have a distance of about 1/8" above the surface by having the
wheels and nub caster over the material that it is traveling on.
