might not be dark enough for the micro:bot to see. Try increasing the width of the black line or changing the
material (i.e. besides black electrical tape, try using a darker paint, marker, pencil, etc.) used for the black
line.
Robot Doesn't Detect Line
- If changing the width of your line doesn't help, remember line sensor
calibration settings can be very sensitive depending on your environment. Press the A button to calibrate
when the robot is on the
black_line
or change the value being subtracted from the
black_line
.
