Week 11:FigureTroubleshoot circuitry

             At this week, im facing of a bit of problem on Proximity Sensor Circuitry which the sensor does not function effectively as i wish.After a day and refer the circuit to my supervisor it maybe cause of degree of sensing range must be altered.

Figure 5:Proximity sensor Circuit

This work take 2 weeks(week 12-13) to settle/alter up....

Week 10:Testing Prototype to get an end product

Objective:To analyse the final output of product.

After a few month through to build the mechanical prototype and ready with circuitry i had tested for twice to shred the raw plastic bottle with specific sizes.

Figure8:End product

Week 9:Voltage Regulator

Objective:To Study on how to regulate down the Voltage in to the PIC.

The LM7805 takes in a voltage between 7 and 30 volts and regulates it down to exactly 5 volts. The first capacitor takes out any ripple coming from the transformer so that the LM7805 is receiving a smooth input voltage, and the second capacitor acts as a load balancer to ensure consistent output from the LM7805.

Week8:Method of Installation PIC board

Objective:To on installation of PIC Cicuit .

Step1-Insert an IC socket and 2 unit 1k ohm resistor

Step2-Insert 20Mhz oscillator and 2 unit 18pf capacitor

 

Step3-Insert the LED

Step4-Insert 2 unit 0.1uf capacitor

 

Step5-Insert 7805 voltage regulator

Step 6-Insert the pin header for 12V and 5 Volt (12V 0V 5V 0V)

 

Week 7:DC Motor

Objective:To find suitable motor for the project.

Based on my the suitable motor that can shredd thing in heavy load in found this table.This Table state almost same ratio that needed for the project DC Motor.

Figure 8:DC Motor Sample

Model No.	RS-7912SHFC2J2-16116RB
Rated voltage	RS-7912SHFC2J2-16116RB
No load	Speed(r/min)	16500
	Current(A)	0.17
At load	Speed(r/min)	13300
	Current(A)	0.72
	Torque(mNm)	70
At stall	Current(A)	4.7
	Torque(mNm)	657

Week6:Mechanical part(Body)

Objective:Test the mechanical part.

              For this mechanical part the drawing does not very fit as I am sketch this is because due to budget constrain and difficulty in first attempt.I have been Google and go for research, there's have replacement in much better also suitable with the budget.

This is project prototype.

Week5:Proximity Sensor

          In my project circuitry i have decided to use proximity sensor because in order to make my load run as there detecting something that presence nearby.The maximum distance that this sensor can detect is defined "nominal range". 

          Some sensors have adjustments of the nominal range or means to report a graduated detection distance.Proximity sensors can have a high reliability and long functional life because of the absence of mechanical parts and lack of physical contact between sensor and the sensed object.

           Proximity sensors are also used in machine vibration monitoring to measure the variation in distance between a shaft and its support bearing.

Here i'm attached a circuitry drawing of Proximity Sensor that i searched from the web and also i'm using this circuit drawing as a reference to my sensor circuit for my project.

Week4:Roughly main program (unfinalist)

//#define use_portb_lcd TRUE  //
//#include<lcd.c>  //

#byte portc=7
#byte portd=8
void main ()
{


set_tris_d(0);
set_tris_C(0XFF);

portd=0b00000000;
}

Week3:PIC schematic

Objective:Study and research on basic Micro Controller diagram

Function of Relay

• Power amplifier
• Peacekeeping / isolator
• Implementation of control logic

Week1:Explainantion of Controller

A microcontroller is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. PIC used is a 40-pin consisting of several components:

o   Power Supply

o   For the power supply, voltage required by the PIC is 5Vdc. For this project the input voltage in use is 12Vdc.12V obtained either from a 12V battery or 12V adapter. Therefore we need a 7805 voltage regulator to drop the voltage from 12V to 5V.

Figure1:Power Supply

 

o   Oscillator

o   Each microcontroller need oscillator to operate. If no oscillator the microcontroller cannot read the program in it.

o   Port

o   Port is a group. Each group have their own name. The group name is given A (A0-A5), B (B0-B7), C (C0-C7), D (D0-D7), E (E0-E2).

o   Reset

o   In the event of a hang on microcontroller, how to be done is short on pin 1 to pin 0V.

Explanation of Block Diagram.

                 In first stage the plastic waste will be compressed by manually. After that, plastics waste will be put into shredder container and shredding machine will start shredded the plastics waste. In this first stage of shredding it will cut horizontally using motor at speed 1500 rpm.

          Then the plastics waste that had been shred horizontally will push into below container that will work as vertically shred the plastics waste from first stage. Same goes here where 1500 rpm motor speed will be apply.

          At the last stage, the final plastics waste that done and evenly shredded will transfer into final container bin.

Methodology on Block Diagram

          This section delivers the information about the methodology that will be used on the machine. This section also will describe the operations of the machine by referring to the block diagram.
