It’s important when dealing with any kind of electronic equipment to put safety first. You should make sure that you avoid giving yourself an electric shock at all costs, as they can be extremely dangerous and might even be fatal. Here are some of the important steps for keeping yourself safe:

  1. Understand the difference between AC and DC voltage, and know that both can harm you if not treated with caution:
    1. AC voltage can reverse direction. This can work to make your heart change its usual beating pattern. People can end up dying from this if their heart cannot regain regular beating.
    2. DC voltage will cause muscles to contract and seize up, and if your body begins to act as a conductor, you might be unable to let go. This can also prove fatal, so ensure that somebody cuts the current as quickly as possible.
  2. Never, ever handle electrical equipment with wet hands. This can also include having sweaty skin.
  3. Do not wear metal jewellery. This includes wedding rings – they will need to be removed when working with electronic equipment and currents.
  4. Have a good understanding of how electricity works. Electricians often keep one hand in their pocket so that if a shock does occur, it will travel out of the body rather than being passed from hand to hand and going through the heart.
  5. Use a multimeter to check whether any electricity is present.

Many electronic circuits will be able to detect invisible light, which is often called infrared. An infrared light is defined as a light that has a frequency of between 1THz and 400 THz. Its spectrum sits between microwaves and visible lights.

With infrared, the lower the frequency the higher the wavelength. This is known as an inverse relationship. Waves are between 0.75 and 300 micrometres – any shorter, and the waves would become visible light.

Infrared light can be very handy and has many uses. It is often made use of in night-vision cameras to allow people to see objects in the dark. The reason that it can be used in this way is to do with Planck’s law, a principal of physics. All matter emits electromagnetic radiation when it has a temperature of above zero, and some of this radiation will be within the infrared spectrum. Therefore, a circuit designed to detect infrared light will pick this up, allowing the human eye to effectively see in the dark.

Infrared also has many other uses, but perhaps the most common use is in a television remote control. The device communicates with the television using infrared technology, allowing people to operate televisions with a small handheld device.

An electronic chip is also known as an integrated circuit. It consists of components such as transistors, resistors and diodes which are all contained in one small plate. The plate will be made from a semiconductor material, most often silicone. It consists of many complex layers of semiconductor wafers, copper and any other required materials.

Chips are very advanced and can sometimes contain billions of components in a tiny surface area. They have been around since the mid-20th century and modern technology has now made it possible to mass produce them using photolithography.

Electronic chips are essential in modern electronics. They are fairly cheap to produce, and their performance can far outweigh that of a discrete circuit. The amount of information they can hold makes them perfect for constructing small yet powerful pieces of equipment, such as a computer. If a computer was built using the same kind of printed circuit board that might be used in other small electronic components, it would need to be enormous – 8 electronic switches would be required to store just one byte of information.

Chips are used in numerous everyday devices and have transformed microelectronics. They can be found in satellite dishes, cars, computers, mobile phones and aeroplanes, to name but a few.

When working with electronics, you should gather up as much information as you can. This is made easier by data sheets, which are available for integrated circuits and are very easy to find. All you need to do is search for them on the internet and you will be able to download all of the information which you need. Here is a brief summary of what you can find on an integrated circuit data sheet:

  • Manufacturer and part number.
  • Details of what the circuit specifically does.
  • Internal circuitry information. This will usually be presented in the form of diagrams and charts.
  • Information about how the circuit will react to different operating conditions.
  • Technical specifications, which should include information about the maximum voltage and maximum current loads for output pins.
  • Required operating temperatures.
  • Formulas to work out operating characteristics. This could include details of how external components will affect the circuit if relevant.

All you will need in order to find this information is the IC part number. This should bring up all the details you need. If you ever require more information, get in touch with the manufacturer. Data sheets may contain slight variations on this information, but they can generally be assumed to contain these details.

A multimeter, or multitester, is a piece of equipment which is used for measuring various aspects of an electronic circuit, such as current, resistance and voltage. It is a useful tool to have and is very easy to use.

Most multimeters aren’t expensive and shouldn’t set you back more than around £20. Some will be more expensive but they may have features which aren’t necessarily required. You may also be able to get one cheaper, which might be a good purchase if you are using one for the first time.

Multimeters are available in digital or analogue varieties. Digital ones will be easier to use as they will show measurement values on a digital display. Analogue will require you to take readings from a scale behind a moving needle, so they’re likely to be less accurate.

Whatever multimeter you choose, it will have two test leads, one red (positive) and one black (negative). Both will have a metal probe on the end which will plug into the circuit which you want to measure.

The multimeter you decide to buy will depend on what you want to test with it. Sometimes they can be used as a bench instrument, but often they will be small hand-held devices. They can be used in the diagnosis of problems affecting industrial or household devices including pieces of electronic equipment, wiring systems and appliances.

Electronics involves controlling electrical energy in order to make electronic devices work. It comes from electron mechanics, which involves studying electrons in an applied electric field. These electrons are what will give us an electric current when batteries and generators are used. Usually, electronic technology will be used to process analogue or digital data.

To give the field of electronics its proper definition, it is a branch of physics and technology which studies the electrons and their movements in conductors, semiconductors, vacuums or gas. It is a distinct area of its own, which is considered separately to electrical and electro-mechanical technology. It used to be known as radio technology due to its close relationship with transmitters, receivers and vacuum tubes.

Devices which control the flow of electrons are called electronic devices and they form part of an electrical circuit. Most electronic devices these days make use of semiconductor components. Some of the most commonplace electronic devices which we use in our everyday lives are computers, mobile phones, televisions, digital cameras and ATMs.
