Essential components to make DIY Electronic projects

  • Arduino and Raspberry pi
  • DC Motor
  • Micro servo
  • Switches
  • Resistors
  • Breadboard
  • Jumper wires
  • Piezoelectric Buzzer
  • Potentiometer
  • Battery
  • DC Water pump
  • DC Air pump

Here i gave basic introduction to above electronic components along with How Electronic components work

Please note these explanation is sufficient to make projects from these components for more in depth explanation Google search can be your best friend!


  • is One of popular board use to control electronic devices
  • Which include sound sensor, soil moisture sensor, ultrasonic sensor, finger print sensor and the lists are endless
  • Here IDE which is software will be use to interlink components and Board
  • Depending on code various controls can be attain between components here code varies as components vary
  • There are various size of these boards
  • Smallest one are Mini other variants include popular UNO and Mega
  • Few project examples automatic hand sanitizer, dog feeder, walking robot and social distancing alarm

Raspberry pi

  • Python, java and c can be use to program raspberry pi
  • Mini computer is interesting project which works like real computer
  • IOT and machine learning projects are made using this board
  • It comes in various sizes
  • Recent versions are Raspberry pi 400 and Raspberry pi Pico
  • Has inbuilt Wi-Fi, Bluetooth and temp sensors
  • Projects include Wi-Fi camera and Wi-Fi rover

How Electronic components work DC Motor

One of most used component by beginner to electronic projects is DC Motor, here we will be talking about only toy dc motor

  • DC Motor works on principle of EMF
  • Motor is designed to get rotational force as output when power electric energy is given
  • To name few Remote vehicles, dc motor water pump, dc air pump, DC geared motor, Dual shaft motors and the list goes on

Micro servo

  • Micro servos has high torque because of gears
  • Small micro controller will be use to control the motor
  • It has gears attach to shaft of motor
  • Reduction and expansion of gear depends on type of applications
  • Micro servo comes in plastic geared and metal geared versions
  • Commonly used to make robotic arm and other robotic projects where torque is key

How Electronic components work Switches

  • Switch act as interface between power supply and control object
  • Use to on and off circuit
  • Comes in different sizes and shapes
  • selected for use as per type of application and usage of power
  • Low power switch cant be use in high power application same applies in other way round


  • These are use to control the flow of current
  • For example if you want to glow 2v LED Diode with 9v battery resistor is necessary because led are rated to max 2v so direct usage will burn bulb
  • Resistor values are different for different power requirement
  • Determined using color codes each color has its own value
  • V=IR is general formula for calculations
  • Inductance and resistance found from above formulae


  • If you want to interlink various components breadboard is easiest way
  • Breadboard has tiny holes which are connect internally in vertical or horizontal way
  • Power rails run vertically means if you provide power to one line remaining all the lines have power
  • Alternative to PCB
  • larger circuit needs more wiring that makes the overall view of project messy

Jumper wires

  • Used to connect holes inn breadboard externally
  • Has connectors at the end
  • Male to male, male to female, female to female are types of jumpers

How Electronic components work Piezoelectric buzzer

  • The name piezoelectric as it uses this component to work
  • Buzzer works because of change in shape
  • When voltage is pass as result of change in shape between material vibration occurs which is sound
  • Used as alarm in most of projects

How Electronic components work Potentiometer

  • Used to vary the resistance
  • Resistance can be change by usage of different resistance value materials
  • Use to control flow of current
  • Similar to resistor but here resistance can be change in real time while in resistor its constant
  • volume control and speed control devices


  • Portable power storage devices
  • Variation in sizes, shapes and capacities
  • Using batter makes the project free from wires attached to power adapter
  • Comes in rechargeable and non rechargeable type

DC Water pump

  • Extended application of DC Motor
  • Uses impeller attached to shaft encased in cover
  • Designed in well manner to receive and give water
  • Size available from types which fits in palm to size of building
  • Here from small water pump liquids can be transfer from one place to another
  • Used to make small Aquarium, automatic hand was sanitizer
  • Small type include submersible version

DC Air pump or DC air motor

  • Same like water pump instead of water impeller diaphragm is used
  • Sealed with extra attachment containing diaphragm on shaft
  • Can be use to make balloon inflator, cycle tire inflator
  • Big version of these used in air blowers which includes industrial grade as well

Well that was about How Electronic components works, Thanks for showing interest
