Ebike Push throttle

Hi guys,

I'm new here but I've been following you and your amazing projects for a while.
I've made a couple of e-bikes and the last thing I needed was a throttle. I know they are cheap but I wanted it immediately so I made it with a voltage divider and it works flawlessly.



Based on research online it appears that the throttle connect as 3 pins: 1) 5V 2) signal and 3) GND.
The signal of the throttle goes from low as 0.8V to high as 4.2V.
I just needed a way to calculate that with accuracy using the E12 standard range of resistors. So I made the following webpages:

Hope that it can help!

Thanks,
