ABSTRACT:
          To achieve DC motor speed control, we need to interface the DC motor with 8051microcontroller. The four-quadrant operation of DC motors such as clockwise rotation, anti-clockwise rotation, forward braking operation and reverse braking operation can be performed using 8051 microcontroller based circuits.
 In several industrial applications like the moment of conveyor belts in the clockwise and anti-clockwise direction can be done using four quadrant operation of motors.In this case, the DC motor can be controlled using this method.
The 8051 microcontroller block is interfaced with DC motor using motor driver IC, the power supply block provides power supply to the kit, and switch array.This switch array is used to send the control signals to the microcontroller which in turn sends commands to the motor driver IC for controlling the operation of the DC motor.

what is iot ?

very simple way express it is wirs less transmission data from one place to another place
the transmission speed is very high comparee other transimmsion lines where its transimmsion following six channel path in wifi setup where if what run iot then you need some iot appliction kits where they are two types privite network and anothrerr is open source but you need chose open source beacause they are free of cost

where our project your using wifi>>>ip>>>tcp configuare

step 1: esp8266 setup(esp8266 means it module name to may to use client)
step 2: wifi setup
step 3: pins setup
step 4: wifi connection processs and server setup
step 5: condition setup
