old moped

Projects General Guidance
1

Hello everyone

I am working on a small project with an old moped from 1977. engine is being rebuilt for sprint.
in that connection I make a torotrak gearbox
(Torotrak's Full-Toroidal Variator - YouTube)

I want a steering that measures engine speed and regulates gearbox.

case:
engine produces max hp at 12750 rpm. so when I turn the throttle, the arduino will "shift" gears so the engine rpm stays at 12750.

is rpm lowers that gear down. is rpm for high gear shift higher.

1: I need an rotary encoder that can handle the speeds.

2: servo or stepper motor to change gears.

3: An arduino who can read the speeds

hope someone can help me.

with best regards
Daniel

You need someone to send you a rotary encoder, a servo or stepper motor, and an Arduino?

no. I need someone who can make such a setup work

Ah, then you should probably post over in the Gigs and Collaborations forum. There you can find someone who will be able to help you spec out this project and you can negotiate a price for the work.

Use the forum Google search function in the upper right of this page to search for the key words of your project, like "tachometer" and similar. You will probably find many similar previous project discussions and code to get you started.
