Boolean theorems
The boolean theorems are a set of rules from boolean algebra to simplify logic expressions of combinational circuits.
Digital voltmeter ammeter: how to use it?
In this post, are shown how it works and how to use the digital voltmeter ammeter. The component I bought is the DE-2645-02.
2 digital electronics projects
In this post are shown 2 digital electronics projects, using DIP integrated circuits: luminous effect with 74HC595 and a semaphore.
Meet the 4093 (2nd edition)
This is the post’s second edition. Additional information has been added.
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.
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 that has two states in output, high or “1” and low or “0”. Multivibrators can be of three types: Astable, monostable, and bistable. This post shows…
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…
