i am here after searching for code on internet for so long time
i am in a making of a recumbent trike which has a 6 speed cassette at back and a 28 tooth cog mounted on the motor shaft
which spins max at 550rpm.
it is at 1:1 ratio on first gear and attains a speed of 40kmph on load.
at a speed of 40 it need to change the gear to 2nd automatically and go on accordingly when speed increased.
but, am not at all in touch with programming.
i only know a bit about circuit. it should have to use a reed switch to calculate the speed of the back wheel (26inch wheel) and send a signal to arduino when speed is around 40kmph to change the gear from 1 to 2 till 6th and should auto return to 1st when speed decreases.
i will be using a geared motor with pulley mounted on the shaft.(pulls the derailleur cable as the arduino gives signal)
here is the thing some one made 100% what i needed but should change the rpm values.
(code is not posted there) : https://create.arduino.cc/projecthub/shift4me/auto-gear-changer-for-bicycles-53e9d3
please if any one knows about this please share the code and circuit diagram .
everything on the trike is electronically controlled but not the derailleur so, i need this to be automated also
(ignore my english am not that educated :| )
