MIGA – Circuito LED simple para principiantes

Descripción general

This is a simple walk-through guide for the beginner to learn how to use the breadboard to build a circuit based on your design. This guide will include:

• Understand the breadboard
• Preparación
• Wire and components
• Power on

The circuit diagram for this guide is:

Understand the breadboard

En primer lugar, before we start to build the circuit, we need to understand what is a breadboard?

Breadboard is very commonly used in the lab for building the

temporary circuit. By using a breadboard, soldering is not needed and is easier for the user to change the connections very quickly.

The first thing that we need to do is to attach the power rail to the top and bottom of the breadboard.

After attaching the power rail the breadboard should look like this.

In the diagram above, you can see some green lines that represent the common connection (row and column).

Por ejemplo, the wire/connections inserted in A1 is

electrically connectedto B1, C1, D1, E1. This applies to the power rails as well.

Preparación

There are a few preparation steps we will usually take before start making connections. The very first thing to do is to connect the power rails.

As you can see the (+) rail on top is connected to the bottom (+) rail. Same thing applies to the (-) rails. This is much

easier for us to make connectionsy

easier for the wire managementswhen circuit is getting more and more complicated.

En segundo lugar, If we have a lot of components, we need to plan the placement of the components. This is very simple but crucial step to ensure minimum wire crossing on the breadboard. But in this guide only a few wires are needed so it is not very significant.

Wire and components placement

En primer lugar, we look back the circuit diagram.

The important thing we need to beware is the polarity of the components.

As you can see in this circuit diagram, el (+) polarity of the

fuente de energíais connected to one of the terminals of the 330ohm

resistor.

Then another terminal of the

resistoris connected to the

anode(which is also refer to the positive terminal) del

CONDUJO. El

cathode(negative terminal) del

CONDUJOis connected to the (-) terminal of the

fuente de energía.

So we can now place the resistor first onto the breadboard. En este caso, I place the resistor in hole E12 and F12. The resistance of the resistor is set as 330 ohm.

Próximo, I place the LED in hole

F18for anode (+) y

E18for cathode (-).

IMPORTANTE: Please look carefully for the anode (+) and cathode (-) pins of the LED !

Por último, we need to connect each of the components (resistor and LED) to form a closed circuit.

You can compare the diagram below with the circuit diagram to understand better.

Encender

Por último, we need power supply to electrically turn on the the circuit. Based on the diagram below, you can see that the red terminal of the power supply is connected to the (+) power rail and black terminal is connected to the (-) power rail.

Por último, we can switch to the Interact tool and turn on the power supply.

Bien hecho, you completed your very first mini project and hope you will enjoy this guide.

Gracias. =)

Conclusión

Thanks for reading this guide until the end. Please comment below if you have any doubt or questions. It might look strange to you when you first time using the breadboard, but i am sure that you will do better and better after using it for several times. Gracias. =)
