Hello all. I need a speed potentiometer for my 24vdc motor. I heard there is a way to make one from a potentiometer and mosfets. Is this correct? And if so how. Thank you Ron |

That is ok, then we can modify that one. Try add more mosfet's or to see what board you have. How big is the motor? Pozdrav iz Srbije |

Motor is 24vdc and consumes about 12 A But prefer if I can build a wee circuit I do lot of busking with piano and keyboards, but due to my health lifting those and then also depending on parking ,I build this type of mobility scooter. I have two 12v batteries and can switch with a button from 12 to 24 volt. I use the 12 we hen playing music as also my inverter is 12vdc. When I leave I switch to 24 and that will power my motor and steering motor. All I have to do is park it at ge location and switch keyboards on.😃  |

Will have other look. One more bit of help advise needed😃 I also want this cart to be driven remote controlled as it's Easter for me to drive it in and out my van. I have a wiper motor installed and also a potentiometer connected to the wiper. I bought a transmitter and receiver which I also will post photo off. I also do have a small servo, from which I intend to remove the circuit board and install that inside my wiper motor. To make this steering work I'm sure I am missing one or 2 parts. I believe I also need a h bridge. But which one ? As my help greatly appreciated Thank you.   |
