I'm having issue of getting any reading on the scope from the tachometer. I have double checked the connections, tried the test codes provided in the project files. No luck . I came across an old thread describing the same behavior. Odd tachometer behavior - Arduino Engineering Kit - Arduino Forum
Anyone else faced the same issue if so what was the solution?. I am hoping that its not a busted tachometer - I did check it right after unboxing the kit, it worked then.
Thanks in advance
p.s: The led on the tachometer board is on, so its not completely dead.
I have similar issue but my tachometer don't have any led on it, issue was because tachometer is far from the inertia wheel, try to bring near wheel to tachometer.
I am also having the same problem. My board does not have an LED, but it reads a continuous HIGH and never goes low even with a much stronger magnet than provided with the kit is placed close to the sensor. I have searched for a replacement board to no avail. I ordered a new sensor and will try that.
i have a similar problem,
sensor was with led on so i tried I substituting mkr board with another one and it worked.
Now also with the new one has the same problem. should i change it? are there any reason why after some months of work the sensor makes the board not working?
(the board is working properly but for the hall sensor.)
