Things to Consider before buying Electronic Components?


1. Clearly list all features and functionalities of your DIY Automation or Robotics project.

2. List down the microcontroller/SBC, sensors, motors, or other components that may be required.

3. Do keep in mind to add basic electronic components to your list, since they are the basic building blocks for any project. Resistors and capacitors help in controlling current flow, multimeters/voltmeters helping in measurements, and soldering kits help in creating more permanent joints and connections.

4. You should ensure to purchase good quality components, to avoid any kind of short-circuits or injuries.

5. Once you’ve achieved your initial goal, you may continue to build additional features or functionality, by adding more components or by upgrading your technology.

6. If you want to buy electronic spares through online electronic components shopping sites in India, you can always go through Robocraze for the best electronic components purchase. It has plenty of cheap electronic components online India. Robocraze being one of the best electronic components website and the best online electronic components shopping sites in India where you can choose more than 100s of   electronic components.

Electronic components are necessary to support your circuits and avoid short-circuits, or ‘blasts’. Since every circuit has different requirements, the components must be wisely chosen.


Integrated Circuits (ICs) are of many types and variants. ICs would be able to take up specific functions it's designed for, and many of them can be combined to do a particular task. Examples include 555 Timer, Mux Demux ICs, LM324 Op Amps, etc


Resistors are added in circuits to prevent uncontrollable flow of current and protect components/devices from damage. The resistor have a property to limits the flow of voltage running through a circuit. Resistor values can easily be determined based on the colour bands. The unit of resistor is ohm. When working on any project, each circuit would require a particular value of resistor to function properly.


A capacitor is a passive electronic component that stores electrical energy. It is a passive electronic component with two terminals. It can store up energy for a short period of time. Also the Capacitor have ability to pass only the AC current and stop the DC current. Capacitors care categorized into two main types: Ceramic Capacitor and Electrolytic Capacitor. The property of Capacitor is Capacitance and the unit of Capacitance is Farad.


An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. An inductor typically consists of an insulated wire wound into a coil around a core.  Inductors are widely used in alternating current (AC) electronic equipment, particularly in radio equipment. They are used to block AC while allowing DC to pass.


A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. The primary function of a diode is to allow current, whether AC or DC, to pass in one direction and prevent current flow from the other direction. This is useful in applications where a back EMF is expected.

Buying discrete electronic components vs integrated kits: Which of the two is better?

If you are quite seasoned with the DIY electronics world, you can opt to buy the discrete electronic components you require for your projects.

However if you’re new to the hobbyist world, and you wish to learn about hobby-grade electronics and microcontrollers, it is highly recommended to purchase integrated electronic component kits, as it would provide you with all the essential components required to help you get started with basic projects. Moreover, from a financial standpoint, it might be more beneficial to buy an integrated kit as opposed to getting all of the components individually.


Types of Electronic Components

What are the basic electronic components?

Basic Electronic Components List are:

1. Resistors

2. Capacitors

3. Inductors

4. Diodes

5. Transistors 


Power Sources

1. DC Power generators like Batteries

2. Power Outlet and power bricks 


Measurement Devices and Troubleshooting

1. Multimeters

2. Digital Oscilloscope 

3. Voltmeters


Active and passive electronic components

1. Passive Components: Components that do not require an external source for their operation are called Passive Components. Examples include, resistors, capacitors and inductors

2. Active Components: Components that require an external source for their operation are called Active Components. Examples include, diode, transistors, SCRs, etc 


How to test/check electronic components?

With a digital multimeter

Resistors: To check the resistance of a resistor, First set the multimeter in resistance mode. Connect the probe on both the terminals. The resistance value will displayed on the multimeter. The value might differ a little bit from the exact resistance. For reference you can always use a color code chart.

Capacitors: Set the multimeter in continuity mode. After connecting connect the multimeter's leads across the capacitor. You will hear a  beep as you connect the leads across the capacitor. If it does, it means the capacitor is not working as capacitors do not conduct DC currents.

Diodes: Measure the forward bias voltage with the multimeter in diode mode. It should be between 0.5-0.7 V for a silicon diode and 0.2-0.3 V for a germanium diode. If it displays O.L. or values less than those specified, the diodes are either blown out or shorted out.

With a circuit board

LED: You can build a circuit that takes 5V input to the positive lead of the LED and connects a 330+ ohm resistor in series between the power source and the LED (to limit the current). Ground should be connected to the negative lead. If the LED glows when the power is turned on, it means the LED is working properly.

Resistance and capacitance can be checked while the device is in operation by measuring the voltage between the two leads with a multimeter.


Basics of using electronic components

The most popular electronic component uses

Electronic components are the basic building blocks of any electronic device. Components such as resistors and capacitors reliably control the current through the device, preventing all types of short circuits and uncontrolled current flow. But the possibilities of what you can do with electronic components are endless. Easily assemble different components to create thousands of projects. It provides an easy way to develop and prototype ideas to make the world a better place.


How to solder electronic components?

Soldering is the process of joining two or more metal objects together by melting and pouring a filler metal into the joint, the filler metal having a relatively low melting point. Used to create permanent connections between electronic components.


The tools required for soldering are

1. Soldering Wire

2. Solder Iron

3. Flux

4. Soldering Station (optional)

5. Stand (optional)
