poster Presentation

this is poster for presentation at 24 April 2012.you all can see me at DEWAN GEMILANG...

result and testing

this is my result from simulation using protues software and testing circuit using oscilloscope for testing output at the motor rotation.you can see or compare result  from simulation and from testing circuit is same. that way my project is complete . 

first record my project.

This is firs my video for my project ..
 This video just first stage to propose for my adviser TUAN HAJI ZAINUDIN KORNAIN.

so enjoy this video..

part 3 **** mechanical ****

Part 3 is the last part mechanical.

for part 3, I completed the installation of solar panels that are connected directly to the volt meter to ensure the maximum of the voltage received by the solar panel. If seen in the prototype above, I use two different size solar panel.

(1) small solar panel,, (output produced by this solar is used directly as input to be used as the source voltage for the operation of this circuit)

(2) large-sized solar panel,, (output produced are connected directly to the voltmeter to measure the voltage value that can produce and it also made ​​an analysis to turn off the solar panels can receive maximum sunlight.

The most difficult part I experienced in the completion of this prototype is the design of LDR. (Light Dependent resistors). in my research, the pyramids in Egypt is the only building known as the "building no shadow" as structure triangle-shaped construction, which is each side of building is bathed in sunlight. so from where Iapplied this concept in this prototype to ensure to the four LDR function effectively.

part 2 **mechanical **

Today I have completed Part 2 (mechanical)

Part 2 involves the movement of the motor 2, which involves the rotation of the motor 360 degrees from top to bottom.

The fixing must take into account many factors

   1) altitude of the motor position (allowing rotation of the motor is not interrupted)

   2) use of the central pillar (center pillar used to support the solar panel bars see picture     above)

Mechanical

                                                       PART (1)

For part 1 (mechanical part), I use prospet transparent to serve as a base to stick DC motor and as we now prospet transparent have strength to accommodate rotation of DC motor.and another advantage to give first impression for our supervisors Tn.Haji Zainuddin Kornai  for flow design mechanical part.

This picture above is base for rotation 360 degree .so this motor will control that rotation to get the angle to get the best of light sun.

circuit pic

this is circuit for PIC controller ..i use pic 16f877A for control my prototype... because.

The 16F877A is one of the most  popular  PIC microcontrollers  and it's easy to see why - it comes in a 40 pin DIP pinout and it has many internalperipherals. 

The 40 pins make it easier to use the peripherals as the functions are spread out over the pins.  This makes it easier to decide what external devices to attach without worrying too much if there enough pins to do the job.  

One of the main advantages is that each pin is only shared between two or three functions so its easier to decide what the pin function (other devices have up to 5 functions for a pin).

motor driver circuit..

complete etching circuit pic +lcd

This task i complete to etching PIC + LCD circuit .Alhamdullilah I for this circuit I don't have  any problem to complete  our task.

DC motor

circuit layout

today I completed the layout for the LDR sensor circuit ... use ... but after arching process ,i detect a problem witch is  i did  not  paste the circuit design on to the board correctly ... 

after ...design using deptress.....this circuit using op-amp (lm238)....

design for ldr circuit sensor ..using op-amp.....

Current Progress

Basically, the current progress is to observe what type circuit and component that include in this project. Therefore there are four type of circuit that must have to run this project.


Pic Circuit
Comparator circuit
Power supply circuit
Dc motor circuit

Short Description of The Circuit 

1. Pic circuit is the main controller of the all function of the circui such as the movement of the DC motor, rotation of the PV cell,  receiving the data from Light dependent resistor (LDR)  and it will display some information and condition of the LDR sensor at liquid crystal display (LCD).
2. Comparator circuit  is use to amplified the signal from the LDR sensor and it also act as the interfacing between the transducer and pic circuit.
3. Power supply circuit is use to transmitted current flow and make deviation current to operated the circuit. For example, to operated dc motor circuit, it requires 12 v and for pic circuit, it required 5v only. Both of this circuit use the different value of voltage and this power supply circuit is come out to fixed this problem.
4. Dc motor circuit is use as the interfacing circuit from pic circuit and dc motor. By theoritically, dc motor cannot be joining directly with pic circuit.  Therefore it must have some medium that must be used to joint this both item to operated the movement of dc motor.

This four circuit is in the design mechanical / circuit development. It is very important to know and classified the type and the function of all this circuit to make sure that in the future, there are no problem encounter  in the part combination all the circuit with programming development.

circuit layout

today I completed the layout for the LDR sensor circuit ... use ... but after arching process ,i detect a problem witch is  i did  not  paste the circuit design on to the board correctly ... 

First our design for solar tracker.

this prototype is my first design for FYP Solar Tracker (OPTIMIZATION OF SOLAR POWER ANGULAR AND DIRECTION POSITION FOR SOLAR TRACKING SYSTEM) .This design give first over view for movement solar penal to capture the best angle to get the maximum light of sun..If you see my prototype have 2 motor to give rotation ,first rotation (motor 1) will rotate 360 degree (left and right) and second rotation  (motor 2) will rotate 180 degree (up and down)
