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.

Week 1 FYP 2 - Research

For this week, I make research the circuit charger for my project. My circuit project must cut off automatic voltage when the battery was fully charge. I will use relay 12VDC for cut off the voltage because inside relay have normally open and normally close. When charge the battery, the relay will be in normally close and when the battery fully charger, it be turn to normally open.
