There has been a few comments about the drawing. Its drawn with Paint with a size of 1776X928 pixels. This looks clear to me. But OK. Will do next time. BTW it is NOT Fuzzy.
Hi DaveEvans.
Both the RPM and the Thrust are working fine before combining the code.
The Load cell code.

Johnerrington.
The power supply does have a decoupling circuit in.
Thanks for the inputs.
