To find the resistor value, you need to know the voltage and the amps for your LED and battery. Next, you need to find out what voltage your battery is. In this example, we will be using a 9V battery. This will give you a voltage of 7 which needs to be divided by.

This project is a great starter project for beginners. We will be using test leads to create a temporary circuit without having to solder it together. You can however connect an LED to a 3V or smaller battery without a resistor. Another way to create and test a circuit is to build it on a breadboard. These boards are essential for testing and prototyping circuits because no soldering is needed.

Components and wires are pushed into the holes to form a temporary circuit. Below the holes of each row are metal clips that connect the holes to each other. The middle rows run vertically as shown while the exterior columns are connected horizontally.

These exterior columns are called power rails and are used to receive and provide power to the board.

Breadboards will need to have power supplied to them and this can be done in a few ways. One of the easiest way is to plug the wires from a battery holder into the power rails. The red arrows in the image below help to show how electricity is flowing in this circuit. All components are connected to each other in a circle just like when we used the test leads. There are a lot of great places online to find electronic components, parts and tools.

Below is a list of our favorite places to shop for electronics. We truly believe that adding a makerspace to a school or library can help students acquire the skills needed for the 21st century. Copyright Makerspaces. There are typically two indicators to let you know what direction electricity will pass through and LED. The first indicator that the LED will have a longer positive lead anode and a shorter ground lead cathode.

The other indicator is a flat notch on the side of the LED to indicate the positive anode lead. Keep in mind that not all LEDs have this indication notch or that it is sometimes wrong. Like all diodes, LEDs create a voltage drop in the circuit, but typically do not add much resistance.

In order to prevent the circuit from shorting, you need to add a resistor in series. To figure out how large of a resistor you need for optimum intensity, you can use this online LED calculator to figure out how much resistance is needed for a single LED. It is often good practice to use a resistor that is slightly larger in the value than what is returned by calculator.

You may be tempted to wire LEDs in series, but keep in mind that each consecutive LED will result in a voltage drop until finally there is not enough power left to keep them lit. As such, it is ideal to light up multiple LEDs by wiring them in parallel. However, you need to make certain that all of the LEDs have the same power rating before you do this different colors often are rated differently. LEDs will show up in a schematic as a diode symbol with lightning bolts coming off of it, to indicate that it is a glowing diode.

A switch is basically a mechanical device that creates a break in a circuit. When you activate the switch, it opens or closes the circuit.

This is dependent on the type of switch it is. As switches get more complex they can both open one connection and close another when activated. This type of switch is a single-pole double-throw switch SPDT. This would break two separate circuits and open two other circuits, every time the switch was activated. A battery is a container which converts chemical energy into electricity. To over-simplify the matter, you can say that it "stores power. By placing batteries in series you are adding the voltage of each consecutive battery, but the current stays the same.

For instance, a AA-battery is 1. If you put 3 in series, it would add up to 4. If you were to add a fourth in series, it would then become 6V. By placing batteries in parallel the voltage remains the same, but the amount of current available doubles. This is done much less frequently than placing batteries in series, and is usually only necessary when the circuit requires more current than a single series of batteries can offer.

It is recommend that you get a range of AA battery holders. For instance, I would get an assortment that holds 1, 2, 3, 4, and 8 AA batteries. Batteries are represented in a circuit by a series of alternating lines of different length. There are also additional marking for power, ground and the voltage rating. Breadboards are special boards for prototyping electronics. They are covered with a grid of holes, which are split into electrically continuous rows.

In the central part there are two columns of rows that are side-by-side. This is designed to allow you to be able to insert an integrated circuit into the center. After it is inserted, each pin of the integrated circuit will have a row of electrically continuous holes connected to it. In this way, you can quickly build a circuit without having to do any soldering or twisting wires together.

Simply connect the parts that are wired together into one of the electrically continuous rows. On each edge of the breadboard, there typically runs two continuous bus lines. One is intended as a power bus and the other is intended as a ground bus. By plugging power and ground respectively into each of these, you can easily access them from anywhere on the breadboard. In order to connect things together using a breadboard, you either need to use a component or a wire.

Wires are nice because they allow you to connect things without adding virtually no resistance to the circuit. This allows you to be flexible as to where you place parts because you can connect them together later with wire.

It also allows you to connect a part to multiple other parts. It is recommended that you use insulated 22awg 22 gauge solid core wire for breadboards.

You used to be able to find it at Radioshack, but instead could use the hookup wire linked to above. Red wire typically indicates a power connection and black wire represents a ground connection. If you look at the schematic you will see that the 1K resistor, LED, and switch are all connected in series with the 9V battery. When you build the circuit, you will be able to turn the LED on and off with the switch.

You can look up the color code for a 1K resistor using the graphical resistance calculator. Also, remember that the LED needs to be plugged in the right way hint - the long leg goes to the positive side of the circuit.

I needed to solder a solid core wire to each leg of the switch. For instructions on how to do that, check out the " How to Solder " Instructable. If this is too much of a pain for you to do, simply leave the switch out of the circuit.

If you decide to use the switch, open and close it to see what happens when you make and break the circuit. This next schematic may look daunting, but it is actually rather straight-forward. It is using all of the parts that we have just gone over to automatically blink an LED. I learned their pin layouts by looking up their datasheets. A good source for quickly finding datasheets is Octopart.

Simply search for the part number and you should find a picture of the part and link to the datasheet. For instance, from the datasheet for the 2N transistor, I was quickly able to see that pin 1 was the emitter, pin 2 was the base, and pin 3 was the collector. Aside from the transistors, all of the resistors, capacitors, and LED should be straight-forward to connect.
