WEEK 13 (FYP 1)

TITLE:Learning Progress of Main Component For Home Automation System
DATE:30/10/2017-3/11/2017

ACTIVITY:

• Study on how Arduino Microcontroler and & Bluetooth module works.

OBJECTIVE:

• to undestand the function of main components and how its works. 

CONTENT/PROCEDURE:

• Do research on Arduino board and Bluetooth module

RESULT/ANALYSIS:

1.Arduino Uno

Arduino Uno is a microcontroller board based on the Atmega 328. It is a well build microcontroller board. It is loaded with USB connection port, 16MHz ceramic resonator, power jack, fourteen digital input/output pins where six of pins can be used as PWM outputs, a reset button and six analog inputs. It is an 8-bit microcontroller based on RISC architecture. The Arduino Uno board is shown in figure above with all the parts labeled.

Table above shows the specifications of the Arduino Uno. The board can be powered from the personal computer by connecting it with USB or external source such as the battery or an adaptor. The recommended voltage supply is between 7V-12V as the voltage dips below 7V. The 5V pin on the Arduino board will become unstable and if the voltage rises above 12V which can cause the board to overheat and damaged. To load the program, no addition haedware or burner needed because there is 0.5KB of boot loader build up in the arduini board. It is automatically dumped the program to the circuit. The coding can be written either using Kiel or java software.

2.Bluetooth module

Bluetooth module is the crucial component in this project. It is used to link the smart phones and the arduino microcontroller board. The type of Bluetooth module that will be use in this project is a module which support master and slave mode with serial communication (9600-115200 bps) SPP and UART interface. As shown on figure 3.5, the size of Bluetooth module is 12.7mmx27mm. These features allow the devices to communicate with other Bluetooth-enabled devices like mobile phones, tablets and laptops. This type of module runs on 3.3V to 5V power supply.The range of this Bluetooth module is approximately 10-15 meters.
