What is Arduino?
First understand the Arduino, what are its parts, it works on how many voltages.
Arduino is based on an Italian company that designs and manufactures open Source Hardware Microcontroller and Open Source software or IDE -Integrated Development Environment.
Arduino Board like Arduino Uno, Arduino nano, Arduino mega hardware is such a programmable computing platform, we can work on it, by combining hardware and software, you can prepare an electronic brain and control electronic devices with that electronic brain.
Also read- Pins Description and Hardware Components on Arduino Uno.
What is Arduino?
If you want to understand more easily, then we can say that Arduino as a microcontroller is an empty brain in which you can upload programs by coding through Arduino IDE software, so they are called open source.
Sensors are used with Arduino board such as temperature sensor, rain sensor, LPG gas sensor it may be analog or digital sensors. We can take the output by programming whatever for the output like display, motor running, relay on and off so that light fan can be controlled. You can do a lot more than this with the Arduino board.
The Arduino board acts as the CPU of the computer, now the microcontroller of Arduino which we can take in hand like a small mobile phone, these old-time computers which needed a very big room to keep, Arduino's small microcontroller board is many times better than those computers for making your small projects and control them us you want.
What is an Arduino?
These microcontrollers can read the sensor and write the same value i.e. tell us like a thermometer that senses the temperature and prints the decimal value on the display.
Arduino hardware is such a programmable computing platform, by working on which the user can prepare an electronic brain by mixing hardware and software and control electronic devices from that electronic brain.
To control an electronic device, many electronic projects can be made and machines can also be made from electronic devices like Computer Numerical Control Machine and can use Arduino in the robotic brain, home automation, and many more things. Can be used in many electronic projects and you can make many gadgets from these such as sonar, small radar system by interfacing ultrasonic sensor.
Arduino Board Parts
USB connection
Through this, the code/program written in the computer from the Arduino software can be uploaded to the Arduino board and it does the work of giving power to the Arduino board.
GND Pins
GND is the short form of Ground, these pins reduce the ground for an external circuit to the other terminal.
5volt power supply
This pin is used to give power supply to the entire circuit and another similar pin is 3.3volt which gives a power supply of 3.3 volts to the circuit.
Analog pins
These pins are from A0 to A5 in Arduino Uno i.e. there is a total of six pins, these are analog input pins, any analog sensor like a potentiometer, temperature sensor, etc. Can read or sense and convert received value into digital value or signal.
Digital pins
The digital pin gives an output from the Arduino board, it ranges from 0 to 13, from which it receives output and gives output to all output components like servo motor, LCD display, led, etc.
PWM pins
PWM means pulse width modulation pin, this pin is your PWM sign(~) on Arduino UNO it is 3,5,6,10,11 it is a type of output that is received after input from the analog sensor.
Reset Button
This is a very useful button of Arduino, on pressing or pushing, our uploaded code or program resets and runs/starts again, if we have written our code/program in the void loop, then the Arduino board gets power only once it is run but after pressing the reset button the program will run once again, in such a situation we will not need to re-install the program by a power cut and remove USB cable to check/test the program.
What is Arduino UNO?
The most popular Arduino UNO microcontroller board of the Arduino family, which has an ATmega328 processor, has 16 Input-Output (I/O) pins, which have 6 PWM pins.
This is also good for beginners, if you know the basic fundamentals of electronics then you will be able to use Arduino Uno and Arduino Mega is the largest microcontroller of this family which is used for it.
Arduino also provides electronic projects kits, it can be powered by USB cable and also power with from Ac to Dc Adapter.
Thank You!
Have A Great Day!
