WEEK 4

Title of Activity : Chosing Arduino UNO as controlling method

Objective : To know about Arduino UNO specification and advantage

Content/ Procedure :

The method use as controller is using Arduino Uno as microcontroller for the electric current control to drive a motor.The Arduino Uno is a microcontroller board based on the ATmega32.It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller,simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.It features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter.

Result and analysis :

Some of the key features of the Arduino Uno include:

• An easy USB interface . The chip on the board plugs straight into your USB port and registers on your computer as a virtual serial port. This allows you to interface with it as through it were a serial device. The benefit of this setup is that serial communication is an extremely easy (and time-tested) protocol, and USB makes connecting it to modern computers really convenient.
   
• Very convenient power management and built-in voltage regulation. You can connect an external power source of up to 12v and it will regulate it to both 5v and 3.3v. It also can be powered directly off of a USB port without any external power.

• 13 digital pins and 6 analog pins. These pins allow you to connect external hardware to your Arduino. These pins are key for extending the computing capability of the Arduino into the real world. Simply plug your devices and sensors into the sockets that correspond to each of these pins and you are good to go.

Conclusions :  

• This week I have learned about the advantage of arduino UNO.From what I have study,the nice thing about the Arduino board is that it is relatively cheap, plugs straight into a computer's USB port, and it is dead-simple to setup and use (compared to other development boards).
