8 Things all electronics enthusiasts should know
Being a tech geek or maker, always indulge yourself in DIY electronics programs, and witnessing them come to reality in your hands is amazing, but to make these processes more fluent, you should master some basic techniques necessary for tech and electronics projects.
If you are a tech novice, this composition can definitely help you a lot with your further electronics projects.
There are 8 important things every electronics hobbyist should know.
1. Ohm’s Law
Ohm's law describes the relationship between electric current and potential difference. The current flowing through most conductors is directly proportional to the voltage applied to them. Georg Simon Ohm, a German physicist, was the first to verify Ohm's law experimentally.
Ohm's law is essential for describing electrical circuits because it relates voltage to current, with resistance moderating the relationship between the two.
Ohm's law states the relationship between voltage (E), current (I), and resistance (R). The equation can be simplified as E = I x R.
This law explains how the most important concepts of electricity are related. It is useful to us because it helps us calculate currents and voltages in circuits. Without Ohm's Law, there would be no electricity. Therefore, the great importance of this law is that it allows us to enjoy the uses of our appliances today, such as TVs, refrigerators, players, etc.
Ohm's law is also used in circuit connections such as calculating the power equation. This makes it easier to understand how to wire electrical components without fear of low voltage or electric shock. Parallel or series wiring can be properly applied when Ohm's Law is understood.
Knowing the basic rules of Ohm's Law allows DIY electronics hobbyists to understand electronic project circuits and build projects more efficiently.
2. Resistor Color Code
The majority of resistors, such as those most commonly encountered, are color-coded since printed numbers would be easily removed and difficult to read. To overcome this problem, color rings are used.
Resistor color coding uses colored bands to quickly identify a resistor's resistance value and its tolerance percentage with the resistor's physical size indicating its wattage rating. Components and wires are color coded to identify their value and function.
When the resistor body is large enough to read the print, such as on large power resistors, the resistance value, tolerance, and wattage rating are typically printed as numbers or letters.
Understanding resistor color codes can help you better understand the resistance value of a resistor.
3. How to Solder
Soldering is widely used in the electronics industry for electrical connections, such as joining copper to printed circuit boards. It is also used by plumbers to join copper pipes. Because of its reversible effects, it is very useful in many industries, and you will even see it used in jewelry.
If you take apart any electronic device that contains a circuit board, you'll see that the components are attached using soldering techniques. Soldering is the process of joining two or more electronic parts together by melting solder around the joint. Solder is a metal alloy that, when cooled, creates a strong electrical connection between the parts.
Understanding soldering is really the foundation for doing electronics projects.
4. How to Desolder
Soldering is important, and so is desoldering.
As the name implies, desoldering is the process of removing solder from a joint to enable component modification or repair. Soldering is the process of creating a permanent electrical connection between two or more components by melting and flowing solder.
It is very simple to desolder: you need to heat the solder, remove the component or wires cleanly, and then clean up any solder that is still on the board or component.
Knowing how to desolder is just as important as knowing how to solder.
5. Learn to do C programming
For embedded engineers, C or C++ is commonly used. For hobbyists, many popular development boards, such as the ubiquitous Arduino, are written in C or a C-like language.
Python is the language of choice for many Raspberry Pi users, but you can program your Pi in C or C++ if you prefer. Learning a programming language takes time, patience, and practice. However, with a little practice, you can become proficient enough to handle many hobbyist-level projects. If you're new to C, start with an online tutorial on C programming and work your way up.
A microcontroller is the brain of an electronic system. A microcontroller, as the name implies, is a miniature control unit that senses all input data and operates all outputs in an electronic system.
Microcontrollers are integrated circuits that are used to perform specific operations. For example, how does your washing machine translate your input into an efficient wash cycle? It's all possible because of a microcontroller.
Learning the basics of microcontrollers is really important for building advanced electronics projects.
7. Basic Electronic Tools
It's very important to know things how to use tools to build a project, tools are convenient and can help you save a lot of energy.
There are several tools that you really need to master in the electronics building process.
Wire Cutter: It's used to cut and split the wire.
Glue Gun: It is important to know how to use glue guns to protect your circuits.
Desoldering pump: It helps you to remove the residue that remains in the PCB after you have tried to desolder, which should be done often. It's highly recommended for a beginner.
Screwdriver: An electronic screwdriver is used to open the circuit that you would need to analyze for various purposes.
Digital Multimeters: or DMMs, measure and verify multiple electrical stimuli, including voltage, current, and resistance, and are used every day by technicians and electrical engineers. They combine the functions of a voltmeter, ammeter, and ohmmeter.
Obviously, a maker or do-it-yourself electronics hobbyist needs a DMM that works with both AC and DC. Look for one with as much functionality as you can afford.
8.Basic Electronic Components
Soldering Iron and Wire: These are the things used to solder the wire with the circuit. A soldering iron works with soldering wire.
Bread Board and Jumper wires: The jumper wire is used along with the breadboard used to make circuitry, It is used to create circuits for prototyping your project.
PCB Board: A printed circuit board (PCB) is a thin electronic circuit board used to organize electronic circuits. A PCB can be composed of many different parts. By using copper tracks instead of actual wires, it is possible to achieve the same results without the use of current-carrying wires, resulting in smaller and less bulky boards.
