Electronic Course

Glad to see you here!, as you imagine, to build a robot you need a basic knowledge in electronics, do not worry if you must to have idea of electronics, all that you will learn here, are some very basic knowledge that will serve to build Your Robot.

The robot's brain is going to build a small digital computer that is within an integrated circuit. A component that is called "microcontroller (uC for short), and is one of the most spectacular of modern microelectronics.

The connection and communication of the brain with the motors and actuators of our "bug" intelligent, as well as sensors that will be used to detect obstacles or path tracking, require additional interface electronics that fit the characteristics element that sends the information (such as sensors) and orders (Engines) to the recipient (our uC).

All the auxiliary circuitry is not contained in the microcontroller and will consist of various electronic components such as: resistors, capacitors, diodes, transistors, etc ... The purpose of this section is to briefly, clearly and simply the basic principles that control the operation of those components that are going to work.

Later, you can see in the section of Sensors and Actuators, additional circuitry such schemes and how they connect with each other. If you do not understand or need more information, feel free to visit the forum and ask your question, of all we are happy to answer all your questions! ;P

The fundamental principles of electronics are based on electricity, whose foundation lies in the structure of matter. The atoms of all materials consist of a core and an envelope. At the core of this are the protons, which are positively charged particles and neutrons. The container, rotating at high speed in orbit, are the electrons, which are particles with negative electric charge. When these charges are positive than negative, it is said that the atom is neutral. The electrons in the orbits support a force of attraction by the nucleus. Some atoms have electrons spinning in orbits far from the nucleus, these electrons can escape from the orbit if there is an attraction force greater than the outer core. If this happens to an atom is positively charged. The amount of electrons move from atom to atom per unit time, is what is called electric current and its unit of measurement is the Ampere (A).

The body voltage is positive or negative electrical charge that is volume. This is measured in volts (V). The difference in voltage or potential is the voltage difference between two bodies, and is the magnitude that is of real interest, because when two bodies come into contact, the passage of electrons toward the more positive body attracts them is entirely of the potential difference between them.

The image shows a 9 V battery that powers an LED and a resistance of 1000 Ohmmios, the current flowing, according to Ohm's law. Is I = 9/1.000 = 0.009 A. .

Ohm's Law. When two bodies communicate with different voltage through a conductor cable will produce a stream of electrons to the body which attracts more positive. Ohm's law quantifies the value of electric current (A), which is created by connecting two bodies with potential difference (V) through a conductor cable that has a certain resistance to the passage of electrons. The opposition offered by the body to the passage of electric current is called "resistance" and is measured in ohms.
The formula for Ohm's law is as follows: I (Amps) = V (voltage) / R (Resistance).

The following figure shows the flow of current (electrons) that are attracted by the positive plate, we can say that when we say that the batteries are exhausted, it is because they have lost electrons.

In the top menu you can see information relating to the various components, Take a look at what most interests you, remember that there is also a menu of tricks and utilities on the part of the Left.
