Re: Mechanical speedometer drive solution
I rearranged the code and now it is working well. The motor does not run without input. Starts slow with the optical disk delay, and then seemlessly transitions to the PID code at around 5MPH, and then maxes out at full input.
I attached the motor to a speedometer. I anticipated less load, unfortunately the slow speeds can’t overcome the resistance of the speedometer. It starts to spin at about 10MPH, but works above that. I may be able to increase the power in the optical disk delay code, and also increase the range for that portion of the code, so it switches to PID after 10MPH instead of 5MPH. If that doesn’t work, I will put an optical disk on the motor from the cordless drill and tune the code for that.
