What im trying to achieve is a gear indicator (highlights what gear you are in) NB: these are available for bikes with electronic speedo but mine is cable driven
My thoughts are to fit a micro switch above and below the gear lever which will move the rotary motor when engaged, the motor will have a brush fitted and move over contact pads on each move (which is why i need the increments to be uniform but necessarily a particular distance). A micro switch either side of the motor arm to kill it when at the lower and upper gear limits, each pad will light an LED to represent the gear and the reason i need to operate the motor in both directions with two separate switches is for the micro switches above and below the pedal/gear arm (which im sure you've worked out).
I told a mate today about the idea who is good with electronics (but unfortunately too busy to help) and he laughed at me and said there a fair simpler ways involving programming electronics at which point i went deaf.
Hope this helps you to help me lol
thanks again for your time
