Hi, Not very knowledgeable with this stuff, be kind please. :grin: I have a DC window motor, L298N H bridge motor control board, an UNO, a volume knob thing (potentiometer), power, and a dream... I would like to turn the knob and have the motor increase speed as I turn the knob in one direction.…

Back of the pot labeled 4k7A FWIW

[image] Lskuared: Outside to outside 4.5kohm, no change on turn knob. Mid to right 0-4.5kohm turning knob end to end. Mid to left same as before but 4.5-0 turning knob. No. With the potentiometer set to the middle of the range, what is the resistance from the middle terminal to an outside te…

Ok. Pot set to middle. Measure from center term to outside term 1 = 2306ohms. Measure from middle term to other outside term 2 = 2382 ohms. Not much for markings so best guestimate of center. [16691511896724996659199632317605] .

I did manage to design the gear interface part thing. The end result will be a thick disc that has 6-32 machine screws that protrude and engage the gear. [20221122_141414]

That potentiometer is linear, that's what you need. As discussed, will you be wanting limit switches ?

BTW Read through this post: [image] Share tips you have come across General Electronics Mounting Hardware on Panels, Chassis, etc. It is almost inevitable that when you measure and drill holes in surfaces to mount motors etc., you never get things perfect. T…

Limit switches someday but if i can get the code now that wouod be great. I can just jump the 2 pinout locations for normally closed or nothing for normally open.

Worst case, if this doesn't work on the mill I can use it on my snow thrower project. Motorized chute control. Already installed the lights. Push joystick button, bam, lights. [20220223_132112] [20220317_021514] [20220317_021537] [20220212_123659] c9
