this Project idea is to control 4 parameter using 1 master and 3 slave.Parameter controlled are DC MOTOR, ANGULAR CONTROL OF STEPPER MOTOR, PRESSURE AND WATER LEVEL USING MICROCONTROLLERS. EXPECTED RESULT The micro controller is responsible for the data to be sent across on to the RS 485 bus slaves works according to the data sent across by the master and then controls the motor speed . The master which is responsible for the predetermined level of the speed of the motor if the input exceeds the determined level ,it would then sends the signal to the microcontroller and the speed is adjusted accordingly. Thus the speed of the motor is controlled. Similarly with the help of two others slave we can control liquid level and angular control using stepper motor.
