How did you feed the throttle cable to the handle bars?

What’s the best way to hide the Arduino?? I’m trying to work out where I can squeeze it I want to avoid getting an enclosure but I may have to! Maybe a small waterproof junction box

Good shout can you recommend any?

That’s awesome I’m going to aim to get a finished product on my bike tomorrow had to order another throttle.

Just tested version 8.2 of the code. Works perfectly just as @Evian1040 has reported. Brilliant. I just need to tidy up the wiring and get a road test complete. Completely agree with @Nealh big shout out to @Woosh wouldn’t have achieved this without him. If I am ever in the Southend On Sea...

Wow this is awesome news my participation this weekend has been poor once kids are in school tomorrow I’ll be free to test this looking forward to it!! Thanks @Woosh @Evian1040 @vfr400 for everything and to the original author. My next mission is to build an appropriate enclosure for the...

I’ll try and get some testing in today too with v8.1 of the code.

So it’s really just down to fine tuning the code on the pedals?

Any error numbers? Or are we free of error numbers?

Try declaring it at the top so something like this int pulseonlenght =0;

Sorry @Woosh i didn’t get a chance to test points 2 & 3 I’ll definitely be able to do a test tomorrow morning

For point 1. v8 of the code doesn't return any errors on start up. Error 22 is received when you either stop throttling or stop pedalling. For points 2 & 3 does it matter what version of the code I run on the Arduino?

So I have redone my connectors, and now the bike doesn't return any errors when I use my connectors and join the wires outside of the Arduino, so I am happy my cabling of the connectors is fine. I retested v8 and v9 of the code and they still exhibit the same behaviours. v8 of the code is the...

What connectors do you have on yours?

Yeah I am very tempted to rebuild my connectors the only problem is my crimping tool doesn't cater for small connections. I'll give this a try tomorrow.

So what i was trying to mention in my diagram was that even without the Arduino I get an error by connecting all 4 wires together so ultimately mirroring the normal bike connectivity (PAS -> Controller) but utilising my plug n play wiring. I'll do a proper test in the morning I could have got...

OK unfortunately I won't be able to test until first thing in the morning, however before I do that test I need to explain something which is very strange. I have attached a picture of my setup below, now if I plug 1 to 2 and 3 to 4, and then I join ALL the wires outside the Arduino and then...

Shall I leave the yellow wires joined outside the Arduino too? So ultimately for this test both yellow and green wires will be joined outside the Arduino?

100% confirm that I receive error 22 (after throttling or pedalling for ~3secs) with the scenario you have described above (yellow wires joined outside the Arduino) running v9 of the code.

Do we know what frequency we should be aiming for? This posts describes how to set specific frequencies (Hz) on specific Digital Pins. Arduino Nano Digital Frequency Pins I'll test on a different digital pin and relay results.
