Electronics courses for beginners and enthusiasts, in digital format (.pdf), with free download.
Reading time: 6 minute The SIMATIC automation system is represented by components coordinated with unitary methods of configuration, registration and data transmission. The programmable controllers of the SIMATIC family (S7) represent the basis of the automation system.
Reading time: 3 minute The course presents the circuits known as FPGA (Field-Programmable Gate Array) and CPLD (Complex Programmable Logic Device), respectively, with a focus on the circuits of one of the representative manufacturers of such circuits, Xilinx.
Reading time: <1 minut The Breadboard or Protoboard is a prototyping space generally used for the quick and easy realization of a circuit without the need to glue the wires. Breadboard applications are many, being recommended when you start learning electronics.
Reading time: <1 minut Among the main topics presented in this course, we list: Choosing the right PIC for the task; Writing and compiling your program; Loading program to microcontroller; Elements of BASIC Language; Arithmetic Operators; Boolean Operators; Logical (Bitwise) Operators; Control Structures; Examples with PIC Integrated Peripherals; Examples with Displaying Data;
Reading time: 4 minute Among the main topics presented in this course, we list: A flexible scheduler for single-processor embedded systems; What is the CPU load of the scheduler ?; A closer look at co-operative task scheduling (and some alternatives); Linking processors using RS-232 and RS-485 protocols; Linking processors using the Controller Area Network (CAN) bus; Case study: Intruder alarm system using CAN; Applying "Proportional Integral Differential" (PID) control; Improving system reliability using watchdog timers;
Reading time: 2 minute Among the main topics discussed in this issue, we list: The 8051 microcontroller; Central-heating controller; Strengths and weaknesseses of "super loops"; Creating "software delays"; How to connect a crystal to a microcontroller; Creating an Embedded Operating System; Multi-State Systems and Function Sequences; Case Study: Intruder Alarm System;
Reading time: <1 minut This course presents interactively general aspects described for everyone to understand, regarding the connection of batteries in electronic circuits, experiments with series and parallel circuits, how to read and operate resistors, how to operate and place LEDs in circuits electronics, how NPN transistors work, electrolytic capacitors and more.
Reading time: 2 minute Cells, also called photovoltaic cells, usually have a very small surface area and the current generated by a single cell is small but series, parallel combinations of these cells can produce currents large enough to be used in practice.
Reading time: <1 minut Distortion and noise are two different unwanted effects on signals. The systems are designed to minimize the effect of these two unwanted phenomena. In data communication, if not properly addressed, the effects of attenuation and distortion have the potential to make a data transfer unsuccessful.
Reading time: <1 minut The aim is to study the analog oscilloscope HM303-6 of the German company HAMEG. The paper presents the principle of operation of the oscilloscope at the level of the block diagram and the facilities offered by it.
