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.
What is electric permittivity?
Answering requests, I will explain what is electric permittivity. Many from the area know as a constant, but there is much more behind.
Digital counters
This post is the continuation of the post about flip-flops. The counters are a flip-flop sequencial arrangement and it is one of the most important applications of this type of…
Flip-flops
In this post I will explain what are flip-flops. Are memory digital or sequential circuits whose output depends of the input and the output`s actual state.
The integrated circuit 555
I will explain how the 555 IC (Integrated circuit) works and what you can do with it. This is one of the most useful components you can use in your…
