Week14

This is my poster for my Final Year project presentation.

Week13

 This is a video of my project is ready and functioning properly. This video shows this fan will spin at an angle of 180 'only and all movement is controlled by the ultrasonic sensor which is located in front of the fan. For the fan speed, it is controlled by a temperature sensor that will detect the ambient temperature.

Week12

Transmitt & Receiver Circuit

This circuit shows the system to receive and send signals to the microcontroller to turn this one-legged system. If you will not transmit or receiver of the remote, the system will not work because there is no switch 'ON' to alert the microcontroller to drive the system. picture below is an example of transmit and receiver circuit circuit for this project.

Week 11

POWER SUPPLY

• The main component is the regulator IC 7805 which serves to convert the input DC voltage 12V to 5VDC.
• 5VDC is the operating voltage used by the PIC, sensor, relay driver, and also in the other circuits
• Diode IN4007 functions as a rectifier
• Resistor 1K ohm function as "Load" which allows a small current through it and then light the LED.
• Capasitor functioa as a "Filter" to produce a clean DC operating voltage (filtering the resulting ripple voltage)

Week10

Switching Fan Circuit

This week I make a switching circuit for the fan. This circuit was tested using MPLAB software 1st to determine whether the pairing I do right or wrong, so after all that I began to etching & soldering circuit and the result like the image below.

Week9

Temperature Sensor

Temperature sensor is a device used to measure the temperature of an object, in my FYP project, I use the LM35 type temperature sensor because it can detect the ambient temperature as the temperature inside a room. after the study has been made from last semester, I purchased a component to be in use and has completed this temperature sensor circuit. I attach below the circuit I have completed the picture I provided for this FYP project.

Week8

ULTRASONIC MOVEMENT DETECTOR

This week i research & make a circuit for Ultrasonic Movements Detector. After i get some components i buy at jalan pasar, 1st thing i do a etching for this circuit, 2nd i insert components and solder at this circuit, 3rd testing using battery for make sure it function or not, below i attach a circuit, components and complete circuit i do it now.
