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;
}

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.
