The Difference Between Stepper Motors, Servos, and RC Servos

26-Nov-07

Stepper motors:
A stepper motor’s shaft has permanet magnets attached to it. Around the body of the motor is a series of coils that create a magnetic field that interacts with the permanet magnets. When these coils are turned on and off the magnetic field causes the rotor to move. As the coils [...]

Photo Detectors

24-Nov-07

Photosensors or photodetectors are sensors of light or other electromagnetic energy. There are several varieties:

Most optical detectors are quantum devices in which an individual photon produces a discrete effect.
* Chemical detectors, such as photographic plates, in which a silver halide molecule is split into an atom of metallic silver and a halogen atom. The photographic [...]

Voltage Comparator

22-Nov-07

In electronics, a comparator is a device which compares two voltages or currents and switches its output to indicate which is larger. More generally, the term is also used to refer to a device that compares two items of data. Output voltage will “switch” whenever the input voltage (at the inverting input) reaches the reference [...]

Line Follower Sensor

09-Nov-07

The circuit diagram for the Line Follow Sensor board is shown below:

The board is connected directly to the Light IO board via PL4.
This circuit is very simple. +5V is applied via PL4 pin 4 to the circuit, and 0V is connected to pin 1 [...]

What Is Mechatronics..?

20-Jul-07

Mechatronics is the synergistic combination of mechanical engineering (”mecha” for mechanisms, i.e., machines that ‘move’), electronic engineering (”tronics” for electronics), and software engineering. The purpose of this interdisciplinary engineering field is the study of automata from an engineering perspective and serves the purposes of controlling advanced hybrid systems.
