Week Twelve

Objective:

• To buy component that needed to build circuit
• To construct circuit based on simulation

Procedure:

This week we went to Jalan Pasar to buy components and takes our sensor that been  order. We still used the simulation circuit as our circuit event the simulation not running well. So, here is the list of our components:

1. Resistor 
2. Capacitor
3. PIC16F877A 
4. LCD
5. LED 
6. Bluetooth Module
7. Force Sensitive Resistance
8. Push Button
9. Battery 9V
10. Voltage Regulator
11. 4Mhz Resonator
12. Rectifier Regulator
13. PCB Board

After that, we design the PCB of our project circuit that we also used Proteus. We printed the PCB layout on glossy paper. To attach the ink of circuit layout to the PCB board, we ironed the paper to the PCB between 8 to 10 minutes. After ironed, the PCB needed to be soaked and shaken in a Ferrite Chloride to remove the unused copper. After finished, we need to make sure that all the connection of line in good condition. If have any line disconnect, just add the connection with marker pen. We drilled holes at the PCB board to put component's leg.Then, we arranged the circuit according to the simulation and solder the component .
