There various types of microcontrollers such as family of microcontrollers, PIC microcontrollerand so on. But, microcontroller is frequently used in various applications due to its advantages compared to other microcontrollers.
In this article, let us discuss about the application of microcontroller in science and technology, but, primarily let us have glance about what is microcontroller. What is microcontroller? There are various types of microcontrollers among which microcontroller is used frequently. The use of microcontroller in various fields such as automobile, aeronautics, space, robotics, electronics, defense application, mobile communications, rail transport, industrial processing, and medical applications is rapidly increasing.
Let us discuss about the practical application of microcontroller in some of the fields mentioned above. The advancement in transportation technology is developing the efficient robotic vehicles which can be used for transportation without driver.
This obstacle avoidance robotic vehicle prototype is one of the major application of microcontroller in robotics. For this purpose, an ultrasonic sensor pair is used in this project, which is interfaced to microcontroller. If any obstacle is sensed by the ultrasonic sensor, then a signal is given to the microcontroller which in turn generates an appropriate output signal.
This output signal is fed to motor driver IC which is interfaced to the motors of the robotic vehicle. Thus, based on the signals received from the motor driver IC the motors can change the direction left, right, forward, and backward of the robotic vehicle to avoid the obstacles if any are detected by ultrasonic sensor.
The speed of the motors can be controlled using pulse width modulation PWM technique. The application of microcontroller in medical applications made revolutionary changes in the medical field. The patient health monitoring system with location details by GPS over GSM is an electronic project based on the application of microcontroller. Similarly, the location details of the patient are also sent using a GPS modem and the information is displayed on the LCD display. The electronic voting machine is a practical application of microcontroller in electronics.
The voting machine designed using this project is having eight contestants capacity. Thus, eight push buttons are associated for eight contestants and a master button for polling authority. By using the master button, multiple polling by single voter can be avoided as each voter need to get an approval for their vote only one vote can be polled by one voter to any one contestant. The block diagram of the project is shown in the above figure which consists of various blocks such as a power supply block, push buttons, microcontroller block, LCD display, buzzer, EEPROM, and transistor.
The total number of votes polled to each contestant is displayed using the LCD display interfaced with the microcontroller. Similarly, there are numerous applications of microcontroller in science and technology and a few more of them can be listed as below.

The main advantage in using a DC motor is that the Speed-Torque relationship can be varied to almost any useful form.
To achieve the speed control an electronic technique called Pulse Width Modulation is used which generates High and Low pulses.
These pulses vary the speed in the motor. For the generation of these pulses a microcontroller AT89c51 is used. As a microcontroller is used to set the speed ranges which is done by changing the duty cycles time period in the program. This is practical and highly feasible in economic point of view, and has an advantage of running motors of higher ratings.
This paper gives a reliable, durable, accurate and efficient way of speed control of a DC motor. There are many order to convert electrical energy into mechanical applications in our life that requires DC motor energy.
This is all result from the availability of speed control. In conclusion, the simplicity of speed controllers is wide range, easily and many control speed made DC motors to be common in ways. In most applications, speed control is very devices ranging from toys, house appliance and important. For example, if we have DC motor in robotics to industrial application. It will go slower over rocky process automation in all sectors. Automation road, slower uphill, faster downhill and so on.
So, results into better quality, increased production it is important to make a controller to control the an reduced costs. The variable speed drives, speed of DC motor in desired speed. C motors, are indispensable controlling elements in DC motor plays a significant role in modern automation systems. Depending on the industry.

Direct speed, and to drive a motor at that speed. There current DC motors have been used in variable are numerous applications where control of speed speed drives for a long time. These applications may objectives: demand high-speed control accuracy and good i.To browse Academia.
