The System of Motor Vehicle Engine Racing Limit Control System Based on Oil Condition Level Based on ATmega328 Microcontroller

Research has been carried out for the manufacture of a motor vehicle engine speed limit controller based on the level of oil condition based on the ATMega328 microcontroller. The method used is to read the pressure at different temperatures and certain rotations, if the pressure is too low then the program will determine that the oil condition is bad or it is time to change it, when the oil or lubricant has been determined that the condition is bad then the indicator light will light up. and the maximum engine speed limit will be cut to 6000 rpm so that the engine will not be able to be used for rotations above 6000 rpm. Cutting the engine speed limit has the aim of preventing the engine from being forced to work at too high a speed when the oil is in bad condition so that the engine components will last longer, besides that the indicator also serves as a reminder that it is time for the vehicle to need an oil change.
