In 1817, Mark Shelley, a novel writer, wrote a story named ‘Frankenstein’ in which there was a character looking like a humanoid...
World’s First Industrial Robot
Robot is an automated machine which was booming only in science fiction stories and movies till 1950’s. Even the name ‘Robot’ was first used for characters of artificial creatures in a stage drama directed by Karel Capek in 1920. Isaac Asimov, a well-known writer, has written three famous laws only during the period of science fiction era. So, when did the first robot came into action? What kind of robot it was?

How Servo Motor Works?
Before we look at the working, let us look at the basic components of servo motors: A Controlled Device A Output Sensor A Feedback System A servo motor can usually rotate 45˚, 90˚, 180˚. Servo mechanism is an automatic closed-loop control system in which the device is controlled by a feedback signal (instead of variable input signal) using the comparison of output signal and reference input signal. How Servo Motor Works? When you open...
How IC L293D runs a motor?
IC L293D is a 16 pin motor-driver IC that replicates the basic concept of a transistor. It is built-in with two H-bridge driver circuits to drive two DC motors simultaneously. One of the greatest advantages is that it can run the motor in both directions: clockwise and anti-clockwise. L293D Pin-Out: The L293D is designed to provide bidirectional current up to 600 mA, and the voltages from 4.5 v to 36 v. In this L293D, there are two...
