Potentiometer

The potentiometers have three terminals and are usually used in circuits of low current, for circuits of greater current the rheostats are used. In many electrical devices the potentiometers are what set the output level.

LDR - Important Concepts

The LDR for its acronym in English (Light Dependent Resistor) or photoresistor is a resistance which varies its value depending on the amount of light that hits the surface. The greater the intensity of light that hits the surface of the LDR or photoresistor, the lower its resistance and the lower the light that hits on it, the greater its resistance.

Photodiode

It is a PN junction semiconductor, it has sensitivity to the presence of visible and infrared light. It could be considered that a photodiode is the combination of a common diode and a photoresistor or LDR and in the same way that the common diode has its polarization.

ENERGY EFFICIENCY AND THE MOST COMMON PRACTICES

Energy efficiency is to intelligently use energy to reduce energy consumption, but without reducing our quality of life, we could save energy without being efficient, although efficiency consists of being able to carry out our daily activities with the best practices. It may seem complicated, but we realize that using energy better is easier that it seems.

Types of resistors

There are many different types of resistors available, from surface mount chip resistors to large-sized resistors. Resistors that obey the law of ohm are called linear resistors, that is, the value of the resistor does not change with the variable current flowing through it.

MULTIMETER

WHAT IS A MULTIMETER?

Sometimes also called multimeter or tester, it is a measuring instrument that offers the possibility of measuring different electrical parameters and magnitudes in the same device. The most common electrical parameters are those of voltmeter, ammeter and ohmmeter.

HOW TO SELECT AN MOTOR?

In the selection of an motor for our project, the designer must consider many factors and specifications, including speed range, torque-speed variations, reversibility, operating duty cycle, starting torque and also the weight and size of the engine must be considered.

SERVOMOTOR

what is a servomotor? It is an electromechanical device consisting of an electric motor, a set of gears and a control card, all constituted within a plastic housing. It can control its angular positions, that ism it can be located in any position within a range of operation generally of 180° but can be easily modified to have a 360° free rotation.
