Arduino: About its Structure

Arduino

---

1. Arduino is an open source platform.

2. It has a programmable circuit board that can be programmed with the help of its user-friendly Arduino IDE(Integrated development environment ).

3. This circuit board consists of programmable micro-controller which can sense and control object in the real world.

Here is the picture of the Arduino board :

Types of Arduino:

There are different different types of Arduino micro-controller present in the market.

While selecting the Arduino board you have to consider the type of project you are doing.

Here is a picture demonstrating types of Arduino :

For example :

If you are making some wearable electronics you might be considering Lily pad. which is easy to be seen or integrated with wearable.

Arduino pro mini for small projects etc.

Board Description:

1. Reset: Used to start code again from an initial state(i.e restart loaded code) in Arduino.

2. AREF: Analog Reference used to set external voltage as an upper limit for analog pins(0v to 5v).

3. Ground: It is used to give ground to your circuit. There are several ground pins in the circuit the in all works the same.

4. Digital pins: Used to take inputs and transmit output.

5. PWM :  (~) marked pin are able to simulate analog signals.

6. power: Arduino can be powered in no. of ways one of them is through the USB slot. you can connect Arduino to PC by using USB cable

7. TX & RX : TX(Transmitter) and RX(receiver). TX flashes according to the serial data transmission speed and RX flashes during the receiving process. Flashing depends upon the baud rate.

8. Micro-Controller: It is also known as the brain of the board. IC(Integrated Circuit a micro-controller) differs from board to board. As before uploading sketch you must know what IC you are using.

9. Power Indicator: This led lights every when the board is powered.

10. Regulator: Controls amount of voltage in Arduino board.

11.DC barrel: Used to power Arduino with DC(Direct Current) jack.

12. 3.3 volts: supplies 3.3v to external objects.

13. 5 volts: supplies 5v to external objects.

14.Ground: It is used to give ground to your circuit . There are several ground pins in circuit in all works same.

15. Analog pins: receives analog signals from sensors and convert it into digital signal.
