Hi, my current project involves connecting a cycle computer to my laptop in order to plot graphs etc of data in real time. This is while the bike is in a turbo trainer (stationary), obviously I couldn't look at a laptop when im on the road haha. I currently already have a wireless computer on my bike, and in order to collect the data I figured I would be able to buy an RF Receiver module for my arduino and have it intercept the wireless signals that are being sent to the box on the handlebars. I've hit at problem at that point though. I'm not entirely sure how I would be able to filter out the noise in order to get the signal that is sent each time the wheel rotates, and in all honesty im not entirely sure if doing this via an RF receiver is the best idea (I have no idea what frequency RF the bicycle computer operates at (is there some sort of standard? or is there some way I can find out?))
I realise, of course, that this would be much easier if I were to do it all wired, but that would make it awkward having to remove all wires when I take the bike out on the road. (And I quite like a challenge!)
Any info regarding this would be much appreciated, as I've not really been able to find much online!
Cheers!
