What is Arduino?

Arduino is an open-source electronics platform, which is based on easy-to-use hardware and software. A non-technical person, but having interest to develop some electronic hobby project, can also work on this.

Programming is so easy that a layman can understand and play with it. However, hardware knowledge is required. Since if any mistake is done then hardware can be destroyed and it is about losing money. So be careful from hardware point of view.

The board design is open source; it means that anyone is allowed to product Arduino compatible boards. This is the reason you can find Arduino board in less price also.

Software for sketching is free as well.

 

Types of Arduino

There are many types of Arduino; few of them are given below.

  1. Arduino UNO: The Arduino UNO is the best board to get started with electronics and coding. This is a simplest board from Arduino series. It is robust as well. The microcontroller used in this is Atmel 328. There are total 14 digital Input/output. Means you can use them as input as well as output, by defining them in your sketch. In Arduino world, program is referred as ‘sketch’.


Technical Specification given below
























  1. Arduino NANO: This is the smallest Arduino board. This is smaller than UNO in size but it has more input/output pins to use.


Technical Specification given below


 

  1. Arduino Leonardo: This board has some advance features. One of them is that it can work as mouse or keyboard.

            Technical Specification given below


 

  1. Arduino Mega 2560: It has 54 digital.



        Technical Specification given below
        

 

What can you do with Arduino?

You can make many small & big electronic projects with Arduino very easily.

You can control electronic appliance, control a car, or even make a robot with Arduino very easily. Since there are many libraries available for Bluetooth, IR communication etc. kind of communication.

Arduino user community is very big; you can find solution for almost every problem related to Arduino.

So let us start the journey of Arduino.

Before jumping to Arduino software programming.

We need to understand hardware very carefully, as I have already mentioned that a small mistake in hardware connection can destroy your board.

How to Make Automatic Room Light Controller Without Microcontroller

You must have noticed in some offices or hotels, when nobody is in gallery or washroom, the light remains OFF but when somebody enters the place, light switches ON automatically. In this post I am going to teach you how to make this circuit. Before going ahead I would like to tell you that this is VERY EASY circuit. For this circuit the material we need is… PIR Motion sensor General Purpose PCB - 5x5 cm. Transistor 2222N – 1 No. Relay 5V – 1 No. 1K/0.250W – 2 Nos. 10K/0.250W – 1 No. IN4007 – 2 Nos. LED 3mm – 1 No. Connector – 4 Nos. Few wires. Relay Circuit Concept : We can use any relay of 12V, 24V, 5V etc. but we have to consider power supply or battery we will use. Since 5V power supply is easily available and 9V battery can also be used for 5V output (after using 7805 regulator if needed). So I am using 5V relay. PIR sensor has three terminals, One for 5Vdc Second for Gnd (0V). Third for ...

How to drive high voltage/current load by small voltage signal from a microcontroller?

Sometimes we need to control or drive a high voltage and heavy current load by a small voltage signal. For example, if you want to control water motor with your microcontroller output. We know that microcontroller gives only 5v output which is not sufficient to drive a heavy motor. This circuit, about which this post is, is very-very useful for electronics engineer and hobbyist. So pay attention! For this circuit the material we need is… General Purpose PCB - 5x5 cm. Transistor KN 2222A (TO-92) - 1 No. Relay 5V – 1 No. 1K/0.250W – 2 Nos. 10K/0.250W – 1 No. IN4007 – 2 Nos. LED 3mm – 1 No. Connector – 4 Nos. Few wires. Tools. Concept: Weak signal triggers the transistor and transistor acts as a switch for the relay. You can use any relay of 12V, 24V, 5V etc. but we have to consider power supply or battery we will use. Since 5V power supply is easily available and 9V battery can also be used for 5V output (after using 7805 regulator if needed)....

How to control digital output with serial monitor in Arduino

Hello Friends, in this blog we will be controlling digital output with serial monitor command. First let’s understand the working of serial monitor. Serial monitor in Arduino IDE is a tool which allows communication between the computer and Arduino board via a serial connection, normally we use USB cable for connection. What are the features of Serial Monitor? It shows the data sent from the Arduino board by using the functions like Serial.print() or Serial.println(). It allows to send text or numeric data to the Arduino board, which can be read by function like, Serial.read() or Serial.parseInt(), thereafter you can use this data for further analysis and action. We can use this tool for debugging and monitoring the function of the sketch. There is a procedure to use the serial monitor, below are the steps given. First initialize the serial communication in the sketch as given below. Normally baud rate is set 9600.  Void setup(){          Serial.begin(9600)...
