Iron the paper on PCB

Week 5 FYP 2 - Design of Schematic for PCB Design

Design Schematic Programming Circuit for PCB Design

Week 4 FYP 2 - Design of Schematic for PCB Design

For this week, I design circuit for PCB by using the PCB designer software. I have three options for design the circuit. The three kinds of option are by using PCB designer software, KiCad software and Dip Trace software. I choose PCB designer because it easy and suitable for me to design of schematics for my project. I design schematic for circuit charger battery.

Week 3 FYP 2 - Program Circuit

I use the Proteus 7 Professional to design the program circuit. I use PIC 16F877A as a programming this circuit. In the program circuit, I am using LCD as a display the circuit. Furthermore, I also use keypad for setting the time that want to be set for charger the battery. B3 as a output to control the charger circuit.

Week 2 FYP 2 - Circuit Diagram Charger

Form this circuit, bridge rectifier function as a converter supply voltage from A.C to D.C. IC 7805 as a voltage regulator IC to maintain the output voltage at a constant value and as a power supply for this circuit. The LM311 series is a monolithic, low input current voltage comparator and designed to operate from dual or single supply voltage. The device is also control test volt battery. Relay 12VDC use as a control the voltage circuit. When the battery was fully charge, the relay will cut off the circuit from normally close to normally open.
