this page is what i borght, and has link to data sheet
https://uk.rs-online.com/web/p/hall-eff ... s/7659321/
i have connected brown (vcc on datasheet) to pin 13
blue (ground on datasheet) to pin 12
black(output) to pin 25
ive tryed both rising and falling egde, as im testing with 36-1 trigger wheel(belive it should be rising,let me know if thats wrong)
tested with meter and can see 5v on brown wire to ground and 5v from blue(output) to ground,
when i stick a magent on the end the blue wire(output) goes to 0v
im asuming this is right and should be the high and low its looking for? but down even get a flicker on the rpm gauge on tunerstudio
ive ordeard a cheap osilascope to test, if that no good i can use my mates but hes a long drive away,plus ive never used one yet!
sorry if i sould like an idiot and this is a simple anwser, i have used serch and googled the hell out of it, but im determind to get this right! as have a few more projectes im working that would benifet from fuel injection(multiple classic motorbikes,cars and my beloved daily driver honda cd175) as much as i love the simplicty of carbs ive got to catch up with the year we live in! p.s sorry for the spelling.
any idears on whats to check/test, what signal speeduino is looking for? could it be 5v to 3.3v as my mate sugested?
