I' using this esc: https://hobbyking.com/de_de/turnigy-plush-30amp-speed-controller.html?___store=de_de
Also a simple 12 V power supply.
I could not find any info whether this esc supports forward and backward operation
I'm gonna draw a simple schematic in a moment.
That's a pretty popular ESC. There should be lots of information , videos and tutorials about flashing the turnigy plush with "Blheli" firmware. You use your arduino to do it. When you have that firmware on there you can select bi-direction mode.
