i have started the motors if you see. the value that is read from EEPROM is the "state. and I have given code that if state is 1,2,3,or 4 then the motor will work accordingly by calling modeOne,modeTwo functions.state is storing whether the motor is moving front , left , right or stopped.if the robot is stopped i.e. the state is 4 and the interrupt is called every 20 ms therefore if state ==4 l
