i am making a bike speedo using a motor attached to the wheel, but the problem i have is that i do not know how to work out the voltage for different speeds. such as 5mph 10mph etc etc. i need to know this so that i can change values of resistor so that at different speeds more LED's light up.
any help would be of help
thank you
