I didn't figure out I needed 4 outputs to control a load valve and a throttle. This is for a hydraulic engine dyno. I've tried a arduino setup to control my load valve with a end stop, stepper driver setup as a 0-5v output from the yourdyno with some success but it's not as reliable as I would prefer. I have a rc servo setup for throttle with a pwm output from yourdyno. I'm curious if I can get a can bus IO and set it up to control the throttle. The only reason I really need it is for the sequencer for a break in cycle. This is for small engine dyno. Any input would be greatly appreciated.
