Servo Motor

 What are Servo Motors? Servo refers to an error sensing feedback control which is used to correct the performance of a system. Servo or RC Servo Motors are DC motors equipped with a servo mechanism for precise control of angular position. The RC servo motors usually have a rotation limit from 90° to 180°. Some servos also have rotation limit...

What is the difference between a DC motor and servo motor?

A DC motor has a two wire connection. All drive power is supplied over these two wires—think of a light bulb. When you turn on a DC motor, it just starts spinning round and round. Most DC motors are pretty fast, about 5000 RPM (revolutions per minute). With the DC motor, its speed (or more accurately, its power level) is controlled using a...

Applications of Microcontroller

The reason I find microcontrollers fascinating is that they have been and continue to be such an important part of the electronics industry.  Over the past decade and more microcontrollers have been creeping into our daily lives.  Figure 1 shows how microcontrollers increased in popularity from 1991 through 1996. In today’s...
