@user-tg6wp7xw6w watch this video I made about 3DOF arduino, IBT2 and POT wiring. At 17:08 you can pause the video and see the diagram to follow the wiring method. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DCty8FsZtkY.htmlsi=a4ZkbtyJ8rdwY0SF The circuit is not for sale. It is a free resource on the internet. I cannot sell you anything. Then check Pt 2 of this video for Arduino tuning.
