Hello
I wish to modify the Hall effect up down switches on a cheap LCD display which use a magnet connected to the gear change and two Hall effect sensor
to a run decade counter
I wish to use six outputs to connector to the six wires that feed the digital dash LCD
So each wire will need 2 volts depending on which gear it's in
So it's an up down counter using the neutral switch to show zero
Any help would be appreciated

Do you know how to use a microprocessor, or do design with
logic ICs ?

Hall effect sensors I2C or analog or SPI interface ?

Here some examples -

Thank you for showing interest in my queries thought I new abut about electronics but my text book is directed to digital logic and driving 7 segment display. I have already bought a $10 gear indicator from eBay and also a led up down display to see if I could modify...
Anyway I have bought a motorcycle digital dash which has a gear display indicator built in...
Which I would like to use. These units run 6 wires and is reset by neutral circuit. So I require a decade counter to drive one of the wires depending on the hall affect switches pulsed by the gear change magnet
So basically I want to use a counter as a rotary relaI am currently investigating Arduinos but they have PWM AND no ANALOGUE outputs

If you need counter and analog out you can use PWM to create a
DAC. Arduino has PWM.

Or a PSOC which has both DACs, OpAmps, ADC, Vref as well as ARM core,
and logic, from gates to counters, PWM, COM....
