PAS to throttle via arduino with a fardriver ND72360 project

[glyndwr]

Hi all,

ive embarked on this project in an attempt to make my self built fat bike legal for UK, cant risk it getting confiscated, got too much money into it,

The controller is a fardirver ND72360 which hasnt got a PAS line, so the arduino pas to throttle mod hopefuly solves this.

Im going to utilise a up down handlebar swtich and a 4 bar led light to indicate the PAS level controlled also by the arduino.

Heres the arduino sketch and diagram thats on wokwi with a working simulator to test.

It tests ok, ive got the arduino nano here, im waiting on the led power indicator and switch to arrive before fitting it to the bike.

Whats your thoughts on it.

Thanks
Anthony.

You can choose a "V5" PAS instead, this has a linear voltage output proportional to the cadence and can be connected to the throttle input of the controller directly.

thanks for the info, didnt know things like that existed. Ive been searching for ages trying to find a solution, and the arduino pas to throttle seemed the only option with a fardriver controller.
Ive als=ready bought all the parts now for this modification, although they werent expensive to be honest, if i find it hard to live with on a daily basis i shal lfor sure buy that V5.
Thank you.

Wow, that looks handy. Could avoid needing a CycleAnalyst in some of my builds.

Too bad price and shipping to US is so expensive. Comes out to $33 + $33 shipping. Meanwhile a Grin superharness is just $26 + $20.

I wonder if the potentiometer on this $10 F/V module could be cranked low enough to detect pedaling:

Might need one of those fancy PAS sensors where the signals cancel out when pedaling backwards too.

thank you for the link and advice, do you know if this has been tested with a fardriver controller by any chance, thank you.

No, but you can find some more technical data at EBS Heidelberg. The sensor has a similar voltage range as a generic throttle, I think it should work.
