Hello everyone,
After finishing an awesome Digital Fuel Gauge with Sir Eric, Im moving on to a new project.
Key points:
#1 I can only use PIC16f84a MCU because, its the only one available here and the only MCU in which I have a loader.
#2 We have a broken CatEye Velo 8 bicycle speedometer which stopped working a few weeks ago. Its wheel RPM sensor is still fine because only the computer stopped working (won't power or turn on).
**broken link removed**
So I need help on how to use this CatEye speed sensor to work with MCUs (PIC16f84). Im guessing that the sensor is a hall effect sensor and as observed, you can hear a 'tick' sound everytime the magnet from the spokes line up with sensor.
It would be easier to program and calculate the speed if I can convert the sensors output into an on/off signal (1 & 0 logic just like a pressed always open switch).
Schemes, designs, inputs, CatEye info's on how exactly the sensor works, and anything to help would be much appreciated.
