Motorcycle gear indicator

I’m a student and i have to make a project “motorcycle gear indicator for mechanical transmision”. The system is kinda simple, there is waveshare 18079 display, Arduino Leonardo microchip, three hall sensors( one hall sensor will show neutral gear and the other two from 1 to 6th gear, also there will be potenciometer. Potenciometer will be in place of the revolutions. So the display have to show which gear is engaged and when is the best time to shift to another gear. I need it till may 26
