This is the first part of a series of posts that show an analysis of practical circuits that use an operational amplifier (op-amp).
The SPI, an abbreviation of Serial Peripherical Interface, is another communication protocol used in microcontrollers and peripherical.
The operational amplifier, or op-amp, has great utility on electronics. In this post, it’s shown the operation of this integrated circuit (IC).
The two shown projects to make LED effect using the Johnson counter 4017.
In this post are shown 2 digital electronics projects, using DIP integrated circuits: luminous effect with 74HC595 and a semaphore.
In this post, are shown 2 circuit projects: an AC voltage detector and a cooler with LED effect.
The accelerometer is present in every smartphone, tablet, and portable videogames. In this post, are shown the operation and how to use a module with Arduino.
Was built an integrated laser in a lithium niobate substrate, for applications in telecommunications.
This is a project of a vehicle with tracks controlled by a pair of RF modules and intergated circuits HT-12E (encoder) and HT-12D (decoder).
The shift register is useful for increase the number of the microcontroller’s output terminals and to convert parallel binary data in serial and vice-versa.
