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.

Feeding Power To Arduino

When you are working with your Arduino, you usually feed it through the USB cable that goes to the computer. However, once you finish programming it, either you resign to leave it connected all day to your PC (without being able to turn it off) or you are looking for another way to power the Arduino.

Tape Measure - 7 curiosities

The flexometer or tape measure is a measuring instrument that consisting of a tape graduated in two international systems (decimal metric system and imperial unit system), basically a hardened steel tape wound inside the casing with a lock that allows the retention of the ribbon or its return and allows us to measure lengths.

Boolean Algebra - Laws and Identities

When formulating mathematical expressions for logic circuits it is important to have knowledge of Boolean algebra, which defines the rules for expressing and simplifying binary logical statements. A bar on a symbol indicates the Boolean operation NOT, which corresponds to the inversion of a signal.

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.

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.
