WEEK 9

DESIGN PROJECT HARDWARE AND SOFTWARE

For this week I have met my co-supervisor to discuss about software and hardware to develop this project. Which my co-supervisor is PROF. DR. ZULKIFLI ABDUL KADIR BAKTI. He will help me on my hardware and software until my project success.

I have explain on how my final year project should work. According to my project, he suggest me to use some simple component to less my burden. We have also discuss how my project will look like and know how it will run from the start to the end. From this meeting, its look like i don't have any simulation, because according to my co-supervisor, i will do it directly using hardware and supposed to get the result in the table form in the laptop. For the hardware he suggest to use nodemcu (ESP8266), two channel relay module and servo motor. For the software, I will use arduino.

NODEMCU (ESP8266)

The NodeMcu is an open-source firmware and development kit that helps you to Prototype your IOT product within a few Lua script lines.

Features:

• Open-source
• Interactive
• Programmable
• Low cost
• Simple
• Smart
• WI-FI enabled

TWO CHANNEL RELAY MODULE

The new Relay Module is perfectly made for Arduino application. It has three pins, the VCC, GND and Signal. It can act as switch if the circuit and the load circuit have different supply voltage. It is commonly use if the load circuit is AC. It is a switch used to connect isolated connection from the circuit using a circuit signal. It has red LED that turns on every time the coil is energized or the signal pin has a high input.

Specifications:

• 5V – 12 V TTL control signal
• Maximum AC current and voltage : 10A 250VAC
• Maximum DC current and voltage : 10A 30VDC
• The control signal DC or AC, 220V AC load can be controlled
• There is a normally open and one normally closed contact
• To make the coil of relay energized you must need to have an input of 1 in the signal pin.

SERVO MOTOR

Servo motors have been around for a long time and are utilized in many applications. They are small in size but pack a big punch and are very energy-efficient. These features allow them to be used to operate remote-controlled or radio-controlled toy cars, robots and airplanes. Servo motors are also used in industrial applications, robotics, in-line manufacturing, pharmaceutics and food services. 

The servo circuitry is built right inside the motor unit and has a positionable shaft, which usually is fitted with a gear. The motor is controlled with an electric signal which determines the amount of movement of the shaft.
