·         To demonstrate the automation system of the machine that effectively transforms the waste into useful fertilizer.

·         To evaluate the functionality of the machine this can help to save the environment by recycling the organic waste for agricultural application.

Analysis

Based on project, result is taken by rotation motor and time setting. Then, lamp or heater circuit should detect the actual temperature refer to set point. For example, set point of temperature set is 35°c, if temperature detect below than this value, lamp will switch on to produce heat in drum. Also if temperature over for set point, lamp will switch off mean temperature in drum already achieve the set point temperature. Below are the classifications of heat condition

·         0%- lamp ON in turbo condition (100%)

·         50%-lamp ON (50%) and OFF (50%)

·         100%-lamp OFF (100%)

    Relation between set point and actual temperature

   Conclusion:

   As a conclusion, the main objective of this project is achieved when proved by taken the result of this project.

Run the project

Week 10

Title of the project: Run the project

Objective: Record the data (Input and Output)

Content/Procedure: 

Motor rotate

Lamp heater

Push button

LCD display

Analysis:

Based on the picture, it shows the operation of circuit process. When switch on supply, it show name’s, SP (set point), AC (actual temperature) and αT (time).Set point is the temperature reference and it related with sensor LM35,so if the sensor have a changes it automatically update at LCD screen and if value are below SP ,the circuit heater will switch on to giving heat to make stable condition. Also, push button used to set the increasing or decreasing temperature at set point and time operation. Beside sensor, already locate variable transistor because function as calibrate or voltage reference for circuit. For example, to get the accurate reading of temperature, circuit should set the actual temperature base on the environment. Sensor will be read the actual temperature base on the calibrate setting. DC motor function based on time setting, where doing process of mixing compose material. It not directly rotates because programming’s setting run and stop during operation.

Conclusion:

Circuit operation is the most important to make sure the objective of project achieve. In this work, every circuit already tested and recorded the step operation. On this work, the main part is PIC16F877A because it plays as a heart to control overall operation. So, these circuits already function as expected. 

Construct and soldering component

Week 8

Title of the project:  Construct and soldering component

Objective: Build the actual circuit

Content/Procedure: 

PIC circuit

Heater circuit

Analysis:

While doing this circuit, the important thing that must take note is the actual design of component. If the design has a problem of size component, it cannot be match into circuit. From the picture, component can be locating at circuit and have jumper to another circuit. The jumper used to connect the input and output of PIC such as the variable resistor, sensor LM35 and heater circuit. Also, at input terminal (supply) have a connection to give main supply at the circuit.   

Conclusion:

In this work, the difficulty are face when need to locate component. Student should careful to do soldering process because some component have high sensitivity which can burn and cooper will broke if applying high temperature by solder. So, all work must be careful and make sure component still in good condition.

Construct circuit board

Week 7

Title of the project:  Construct circuit board

Objective: Etching process

Content/Procedure:

1)    Print the design on transparent paper/stick paper 

2)    Stick the design on PCB board

         3) Etching process

                   4) After etching process

Analysis:

First step of etching is stick the design at PCB board and it should paste all of the carbon because it the way of current flow between component. Next, by using etching liquid the process is to erodible the cooper layer until left only copper line at circuit. Then, clean up circuit layer until look shiny and start process of drill a hole of pin component.

Conclusion:

Etching process is important to make sure all connection will connect between components. So, after this process it should be testing to check the connection of circuit in good condition.

Design PIC circuit

Week 6

Title of the project: Design PIC and heater circuit

Objective: To build the interfacing circuit between the motor, heater and PIC circuit

Content/Procedure:

Design circuit by using software

Analysis:

After complete design using proteus, circuit on software will be transform to be an actual circuit. By using Protel Design System, it already locates component and connection of each component. Student should re-check to make sure have no overlapping layer and circuit will be adjust as needed. The important thing, this software will build as an actual circuit, mean component can be place into circuit with component pin can be place at PCB board.

Conclusion:

This circuit is use to connect between the component in circuit. It can be design as expectation of sizes at the PCB board. So, student can print the design and it ready to paste into PCB board.

Run the programming of PIC

Week 5

Title of the project:  Run the programming of PIC

Objective: Record function of circuit

Content/Procedure:

-Check the connection of component

-Burn the program into PIC

Start run program

Setting the voltage reference and LM35

Check push button (increase and decrease)

SP=Set point

Time setting

Circuit Motor

Heater (Led show output to heater circuit)

Analysis:

In proteus, after construct the circuit, program writing will be burn into PIC. Before that, program should be compiling to make sure have no error, if still have an error; program cannot be burn and need some modification. In this case, software will show at which line has a problem, so it make easy to do some correction. If program already complete, circuit can be operate based on the step planning in program such as display name, rotation motor, time setting and input at the sensor(LM53).  

Conclusion:

Based on this work, assemble language play as important part to make the PIC function. Instruction giving refers step planning of circuit operation. It must be related for each circuit because when PIC start operates, each circuit will do their own operation.

;=============== MAIN PROGRAM START HERE========================

Analysis:

To write a program, student should know the language of the software used and the expectation of circuit operation. In this work, before writing a program it should be define the step operation at input and output PIC. By referring data sheet PIC16F877A and ASM software, student can plan what are step need such as time setting, input sensor, push button and LCD display. It must be properly step setting because PIC cannot read if the wrong instruction given also the operation may be interrupt. In this case, student already done some adjusted of the program because PIC cannot run as expected. So, the program should be modified until it can run as step planning. After complete writing program, it should be compile to check where the wrong of language and if have no problem, it show the program successfully build.

Conclusion:

Writing the programming is the important part in PIC because it functions as heart to giving instruction of circuit operation. So, all the instruction must be properly write depend on step and transmit at pins which make it operate.
