Are you using PID and platter sensor?
Have you mounted an IR speed sensor and
connected it to the board. This switches on PID
control. If set to N then the speed of the platter
will still be displayed but adaptive motor speed
control will not be available. We suggest enabling
this after you have the basic non adaptive control
working first.

Is platter sensor active low?
This means the sensor will output 5v (high) until
the white platter marker or magnet is encountered
when it will output 0V. When using a black label
on a reflective surface this should be set to ‘N’ –
change to ‘Y’ for a white label.

Automatically start platter on application of
power?
The board can automatically start the platter on
the application of power rather than having to
press a start switch.

Crystal trim value:
Allows fine trimming of the Arduino crystal
frequency if it is not exactly 16MHz. This is the
master clock so it’s essential that this is set
correctly to achieve exact platter rotation speed.

specifies the correct value to enter here and it
should be set from manufacturing.
