This is the first part of a series of posts that show an analysis of practical circuits that use an operational amplifier (op-amp).
Category: Integrated circuits
SPI communication protocol
The SPI, an abbreviation of Serial Peripherical Interface, is another communication protocol used in microcontrollers and peripherical.
Operational amplifier: how does it work?
The operational amplifier, or op-amp, has great utility on electronics. In this post, it’s shown the operation of this integrated circuit (IC).
2 projects with LED effect
The two shown projects to make LED effect using the Johnson counter 4017.
2 digital electronics projects
In this post are shown 2 digital electronics projects, using DIP integrated circuits: luminous effect with 74HC595 and a semaphore.
AC detector and cooler with LED effect
In this post, are shown 2 circuit projects: an AC voltage detector and a cooler with LED effect.
Accelerometer: how does it work and how to use it?
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.
The first integrated laser
Was built an integrated laser in a lithium niobate substrate, for applications in telecommunications.
Remote control vehicle
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).
Shift register
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.
