Data Sheet
To improve the line following or to tune to the required surface/line:
Slowly move the detector across the line. When the detector gets close to
the line it will switch to the opposite state.
If it does not change, then the pots will require tuning.
To make the detector less sensitive: turn the pot clockwise.
To make the detector more sensitive: turn the pot anti-clockwise

Tuning Guide
The code below is a working code for the :MOVE mini using Kitronik
blocks for a dark line on a light surface (e.g. Black line on white paper)

Software Tip:
Note whether the indicator LED’s on the board are normally on
(light surface & dark line) or normally off (dark surface & light line).
These indicator LED’s are by the pots.
Write the software according to the normal state of the input.
See example code opposite.
