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.
Meet the integrated circuit 4017
In this post, it’s shown the operation of integrated circuit 4017, from CMOS family. In addition to some projects which are possible to make with this chip.
Multivibrators with 2 transistors: astable, monostable and bistable
A multivibrator is a circuit which has two states in output, high or “1” and low or “0”. The Multivibrators can be of three types: Astable, monostable and bistable. In this…
Meet the 4093
This post’s subject is the 4093, it is an integrated circuit very simple and useful to build many electronic projects.
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.
Digital Electronics: Combinational circuits
In this post, I will explain how to design combinational circuits, which are just digital circuits with combinations of many logic doors. Logic gates We have the following logic doors…
