2 years ago the Arduino nano ble sense 33 has a magnetometer on it already, read my blog post to see how the board is mounted. it really depends on your bike where the sensor goes. I think the bike I used is similar to yours. I probably could have connected to the reed switch but I wanted to get varying levels of magnetometer readings for when I changed resistance. if you don't need that you could potentially just use the reed switch and the part of my code that counts the cycles and converts it to speed
hello, I´m interested in replicate this, I noted my spin bike just use a switch reed and a magnet to count speed, so not shure if is to easy,
where you attach the sensor to arduino? I´m trying to read the code, but not sure about those
