Much smoother!!!! ya!!!! Before you could hear a faint sound in the motor from noise because of sloppy A/D conversions. I slowed down the Analog to digital converter sampling rate, and I lowered the delay when the hardware shuts down the circuit. Now I can drive up the driveway at very low RPM.

I decided to floor it down the street!!! hahaha! The car accelerated VERY well, and then the current just held pinned at the current limit. You can hear a faint sound when the hardware current limiting kicks in! It's so fun!

I wish I could feel this at a higher voltage.

Video coming soon!!! ya!!! Controller #2 will be super easy to make! ya!!!!!!!!!
