Thanks Ashutosh for your response. After doing some research, I am selecting this approach, to calculate the speed of bicycle in kph
- Measure the wheel diameter and then multiplying it PI to get circumference of wheel. This distance is the distance travel by one revolution of the wheel.
- If suppose, I am having 30 spokes on my bicycle then setting a counter to 30 in attach interrupt function. If it matched then time is captured and indicating the time travel for one revolution.
Now, with these two measurement I will obtained speed in (m/s) which will be then converted into kph by conversion formula. I hope I am in right direction now. Once again thanks.
