WEEK 8:Schematic Explaination

WEEK 8

In this week I will explain how the circuit function & operating.

LCD DISPLAY SCHEMATIC DIAGRAM

In this circuit diagram I will explain how the circuit function.The main component in this circuit is PIC16F877A the functions is to control all process and it must be program it.The input will come into analog signal and change to digital signal,how the process happen?The process must pass through 3 step first sampling,quantars, and last one are encoding.After that the output will come out to the LCD display.The power supply that use in this circuit are 5v,we using adapter as our power supply.

TEMPERATURE SENSOR SCHEMATIC DIAGRAM

In this project contains 3 circuit board to make this project function.firstly is temperature sensor schematic as our input as we can see at the diagram have amplifier,resister 100k,temperature sensor and preset to control the sensitivity of the temperature sensor.To operating it the temperature sensor will sent input to amplifier and amplifier will amplifir the signal low to high signal to get the good signal or wave

WEEK 7: Constrct & Soldering

WEEK7

For week 7 I doing construct & soldering after I finishing doing the pcb layout.

This some equitment that I used for soldering

solder

solder holder

first step we drill the foll on the pcb board that we do for last week

second step we put the compement on the holl n but same on the schematic diagram,than we solder it

WEEK 6: PCB Development

WEEK 6

I doing the PCB process at PCB Room UNIKL BMI.

Firstly we tap the schematic diagram of the UV
board that we buy.

Than we put the UV board in the UV box

Than we set for 60 seconds to heating the UV board

After that, we that out the schematic plastic and the diagram alreadly scan on UV board after we heating it.Than we clamp it on the board.

Than we put the UV board into the machine to process clean the UV board

This is the acid to clean out totally the UV board

We put the UV board into the box with acid and it will clean out the UV totally.So it will produce PCB layout on the board.

WEEK5:Doing The PCB Layout

WEEK5

For this week I doing the PCB layout for both circuit Temperature sensor board & LCD Display board.
When I doing the pcb layout I using the schematic diagram to do the pcb layout because it more easy to translate to pcb.

Temperature sensor PCB layout

LCD Display PCB layout

WEEK4:Doing The Schematic Diagram

WEEK 4

In this week I doing the schematic Diagram for my project.In my project that has three circuit to run the project.Firstly is input (Temperature sensor schematic) than the input transmit to the LCD display(LCD Display schematic) and the last circuit is KC Wirefree Bluetooth Module Starter Kit,this KC Wirefree Bluetooth we buy not diong the circuit.
