Hi All. first post
I am a newby to this game. I am after using a 7 segment LED to indicated the gears.
My car has a cable controlled gear lever, as I change gear the cable moves in length.
What I am after is a way of taking the output from 7 reed switches in a row to along side the base of the gear lever with a magnet connected to the cable itself, so as i change gear the magnet moves and so operating a different reed switch.
This would require eight wires one connected to all seven reed switches (the positive lead) on one side and the other seven going back to the control unit.
the control unit it self is what I am after.
This would consist of the 7 seg led and the led driver, each reed swicth would give a different input to the driver cct perhaps an arrangement of gate that would give the output to the led driver so it would indicate the gear that I am in.
Using the standard form on a 7 seg led the 1st gear would turn on the segments "b & c"
the 2nd gear would turn on the segments "a,b,g,e, & d"
3rd would be "a,bc,d, & g"
4th would be "f,b,g & c"
5th would be "a,f,g,c & d"
Neutral would be "a,b,c,d,e & f"
reverse would be "a,g & d"
I know its alot to ask but can some kind soul please help.
