Home Beginners Read Circuit Diagram. This articles shows how to read circuit diagrams for beginners in electronics. Learn to read electrical and electronic circuit diagrams or schematics. A drawing of an electrical or electronic circuit is known as a circuit diagram, but can also be called a schematic diagram, or just schematic.

Circuit or schematic diagrams consist of symbols representing physical components and lines representing wires or electrical conductors. In order to learn how to read a circuit diagram, it is necessary to learn what the schematic symbol of a component looks like.

It is also necessary to understand how the components are connected together in the circuit. Probably the simplest circuit that can be drawn is one that you may have seen in a school science class: a battery connected to a light bulb as shown below. Each electronic or electrical component is represented by a symbol as can be seen in this simple circuit diagram.

Lines used to connect the symbols represent conductors or wires. Each symbol represents a physical component that may look as follows. The physical circuit for the above circuit diagram may look something like the image below, although a more practical physical circuit would have a light bulb holder and clamps that connect to the battery terminals. A light bulb holder would have screw terminals to connect the wires to, and a socket to screw the light bulb into. Battery clamps would allow the wires to easily be connected between the battery and light bulb holder.

Typically the actual battery type and bulb type would be specified in a component list that accompanies the circuit diagram. More information on the bulb and battery type could also be included in the circuit as text. For example, the battery may be specified as a The light bulb may be specified as a 12V 5W incandescent bulb, or 9V 0.

Components in a circuit should always have references, also called reference designatorsused to identify the components in the circuit.

This allows the components to easily be referenced in text or a component list. A battery may have the reference designator "BAT" and a light bulb may have a reference "L". Because there could be more than one battery or light bulb in a circuit, reference designators will usually always end with a number, e.

BAT1 and L1 as shown in the circuit below. A second light bulb in the circuit would then have the reference designator L2.

Circuit diagrams or schematic diagrams show electrical connections of wires or conductors by using a node as shown in the image below. A node is simply a filled circle or dot.

When three or more lines touch each other or cross each other and a node is placed at the intersection, this represents the lines or wires being electrically connected at that point. If wires or lines cross each other and there is no node, as shown at the bottom of the above image, the wires are not electrically connected.This pictorial diagram shows us a physical connection that is much easier to understand in an electrical circuit or system.

An electrical diagram can indicate all the interconnections, indicating their relative positions. The use of this Array can be positively recognized in a production project or in solving electrical problems.

This can prevent a lot of damage that even derail electrical plans. The layout facilitates communication between electrical engineers designing electrical circuits and implementing them. The pictures are also helpful in making repairs. It shows whether the installation has been appropriately designed and implemented while confirming the safety regulators. A usually gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device.

This is unlike a schematic diagram, where the arrangement of the components interconnections on the diagram usually does not correspond to the components physical locations in the finished device. A pictorial would show more detail of the physical appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections over physical appearance. Smart Engine Wiring Diagram show the circuit flow with its impression rather than a genuine representation. They only provide general information and cannot be used to repair or examine a circuit.

The functions of different equipment used within the circuit get presented with the help of a schematic diagram whose symbols generally include vertical and horizontal lines. However, these lines are known to show the flow of the system rather than its wires. A represents the original and physical layout of electrical interconnections.

Wiring on the picture with different symbols shows the exact location of equipment in the whole circuit.

Its components are shown by the pictorial to be easily identifiable. They are often photos attached with highly-detailed drawings or labels of the physical components. A person with a strong knowledge of electrical wiring diagrams can only understand a pictorial. FRDiagram Database.

The term "passive" indicates that the sensor does not actively take part in the process, meaning it does not itself emit the referred infra red signals, rather passively detects infrared radiations emanating from warm blooded animal in the vicinity.

The detected radiations are converted into an electrical charge proportional to the detected level of the radiation. This charge is then further enhanced by the built-in FET and fed to the output pin of the device which becomes applicable to an external circuit for further amplification and for triggering the alarm stages. The image shows a typical PIR sensor pinout diagram. It's quite simple to understand the pinouts and one may easily configure them into a working circuit with the help of the following points:.

As indicated in the following diagram, PIN 3 of the sensor should be connected to the ground or the negative rail of the supply. Pin 1 which corresponds to the "drain" terminal of the dvice should be connected to the positive supply, which must be ideally a 5V DC.

And pin 2 which corresponds to the "source" lead of the sensor must be connected to ground via a 47K or K resistor. This pin also becomes the output pin out of the device and the detected infrared signal is carried forward to an amplifier from pin 2 of the sensor. In the above section we learned the datasheet and the pinouts of a standard PIR sensor now lets' move on and study a simple application for the same:. The first PIR circuit diagram for sensing moving humans is shown above.

A practical implementation of the explained pin-out details can be witnessed here. In the presence of a human IR radiation, the sensor detects the radiations and instantly converts it into minute electrical pulses, enough to trigger the transistor into conduction, making its collector go low.

The IC has been set up as a comparator where its pin 3 is assigned as the reference input while pin 2 as the sensing input. The moment the collector of the transistor goes low, the potential at pin 2 of the IC becomes lower than the potential at pin 3.

This instantly makes the output of the IC high, triggering the relay driver stage consisting of the another BC transistor and a relay. The PIR device discussed above is actually a core sensor and can be extremely sensitive and difficult to optimize.

In order to stabilize its sensitivity the sensor should be suitably enclosed inside a Fresnel lens cover, this will additionally enhance the radial range of the detection.

If you are unsure about using an uncovered PIR device, you can simply go for a readymade PIR module with a lens and other enhancements, as described below.

The following PIR motion sensor circuit can be easily built using the following basic set up and applied as a anti-theft alarm circuit.I have been looking for a good stereo amplifier circuit diagram for a long time.

I am not a HiFi geek, I just wanted to build a simple stereo amplifier that could drive some speakers for my desktop computer. All the schematic diagrams that I could find seemed to involve lots of hard-to-find components or you had to use it together with a pre-amplifier or some other amplifier stage.

It was always something that made me hesitate. But recently I found this awesome little chip called TEA! You only need a few capacitors to make a decent stereo amplifier out of it. It is so simple to build that I put it together on a stripboard in just a few hours. The amplifier circuit diagram shows a 2. You can also make a 5W mono amplifier out of it. Check out the TEA datasheet for more information on that.

On the input side, you should use a dual potentiometer. A dual potmeter allows you to connect both the left and right channels on one potentiometer. This amplifier is great to use together with some speakers to get sound on your desktop computer. I am thinking of putting one in my kitchen and in my bathroom also.

This board was made to comply with the design rules of Seeed Studio May I want more people to build better and cooler projects. Everyone can improve even if they are complete beginners or have built many circuits from before. Hello Oyvind, Thanks for this useful post. Can u suggest me some solution to get get the rid of this noise. If the input signal is too high, you will get clipping on the output. This will make the sound noisy. Thanks for your quick reply, I tried your suggested solution and yes the noise is still present at lower volumes.

And one more thingi think i should add, I am using USB power supply.This pictorial diagram shows us a physical connection that is much easier to understand in an electrical circuit or system.
