What developed in the electronics lab maca was very interesting because during the two weeks we were able to make the programming of a station and create a sequence of lights. Thanks to this work could enhance knowledge about what we had was a PLC. The first thing that gave us indications of how the sequence of lights that gave us a series of documents which had drawings of the stations and thus to begin the sequence of lights. At first we were a little difficult as we had to face a new simulator, but a little chat with an instructor is fixed this little mishap. This new simulator was the ability to schedule through ladder is a tool that we met when we worked with logixpro, but I had another way of programming which is called AWL is a little complicated at first because if one is not attentive to what being developed can be lost easily.
The work we do at this time was working with a simulator called logixpro which aims to let us know in a didactic manner the operation of a PLC (programmable logic controller). In what was the job this time was to give solution to a series of exercises in a logical sequence dare. Most important of these was put into practice the knowledge obtained in this way before, and put them into practice as the SFC which is to create the sequence of programming, having come to this step to move from SFC is Ladder another programming language.

Today there are several electronic instruments used in some of the most important are the millimeter source voltage, Cautín, among many others.
This time we will talk about the sources of regulated 1.5 V to 15 with two outputs of 5 to a positive 15v and a negative from -5 to-15v. A regulated voltage source is a device which provides an output voltage of direct current which is needed to operate most electronic circuits.
Based on prior knowledge obtained from studying the sources and build a
regulated explain its operation and the materials needed in its preparation

On this occasion we made an activity for which the transistor was the minimum time in two days which would realize a series of activities including:
A workshop which was to develop exercises, a practice which was to give solution to some cards for the transistors in a maximum time of four hours or make a montage in which to perform the calculations that we called the guide and Finally an assessment to verify that we had actually done the activities and thus complete the activity successfully.

By entering basic electronics in the beginning of our preparation as technologists and explaining basic topics for our development in the automation. Besides the development work that is appropriate to understand and dispel many doubts as to take some basic principles in this way reinforce what is wrong With the completion of the workshop was to assess knowledge and drenched much of the item.

Electronics, engineering and applied physics to design and implementation of devices, usually electronic circuits, whose operation depends on the flow of electrons for the generation, transmission, reception and storage of information. This information may be voice or music (voice signals) in a radio receiver, an image on a television screen, or numbers or other data in a computer or computer. In principle, basic electronics, began in the Second World War with the development of radios, but the evolution of electronics was with the advent of the triode, and the twentieth century brought discoveries that today has become a major factor within the "neo-technology." First, there is a science in physics-based semiconductor and electronic circuits and even further integrated electronic circuits, such as unions have the diodes, transistors, thyristors, etc.. And also the training of basic electronic circuits such as amplifiers, oscillators, Multivibradores, converters, among others, and some passive components such as resistors, capacitors, coils and other assets such as batteries (batteries) and transistors. Electronics can be divided into two main groups: the electronic analogue and digital electronics. And in electronic circuits, there are two kinds of analog circuitry and digital, the analog electrical signals which are continuously changing to match the information represented the basic units of analog circuits are passive resistors capacitors inductors, and active sources energy. And where the digital values obtained by electrical signals to display discrete numeric values that represent logical and information processing.
