FYP2 WEEK1 (2)

Title : Research and findings(relay DPDT-Double Pole Double Throw)

- Buy the components of relay DPDT and relay base socket in JalanPasar.

-Most relays are designed for PCB mounting but we can solder wires directly to the pins provided. For this situation, we must be careful to avoid melting the plastic case of the relay.

DPDT

- Double Pole Double Throw. These have two rows of change-over terminals. Equivalent to two SPDT switches or relays actuated by a single coil. In total, eight terminals when the coil is also included.

FYP2 WEEK 1 (1)

Title :Research about the relay DPDT (Double Pole Double Throw)

ANALYSIS

- For this project, relay DPDT will be used as a backup if there is any power failure.

- Power failure means there is no power supply. There is an alternative way that I can use by using battery of 12 volt. Therefore, this project will be added one more relay of DPDT as a function to replace power supply.

Terminal Pins

A Double Pole Double Throw Relay comes with 8 terminal points.

The terminals are COIL, COIL, COM, COM, NO, NO, NC, NC.

Terminal Descriptions

COIL- This the is the COIL terminal. These are the terminals where you apply voltage to in order to give power to the coils (which then will close the switch). Polarity does not matter. One side gets positive voltage and the other side gets negative voltage. It doesn't matter which order. Polarity only matters if a diode is used.

NO- This is Normally Open switch. This is the terminal where you connect the device that you want the relay to power, when the relay is powered, meaning when the COIL receives sufficient voltage. The device connected to NO will be off when the relay has no power and will turn on when the relay receives power.

NC- This is the Normally Closed Switch. This is the terminal where you connect the device that you want powered when the relay receives no power. The device connected to NC will be on when the relay has no power and will turn off when the relay receives power.

COM- This is the common of the relay. If the relay is powered and the switch is closed, COM and NO have continuity. If the relay isn't powered and the switch is open, COM and NC have continuity. This is the terminal of the relay where you connect the first part of your circuit to.

WEEK 14

Title :  DISCUSSION WITH TECHNICIAN ABOUT RELAY CIRCUIT 

For this week i has meet with technician and ask him about the relay connection, he give some advice about the connection and after discussion with him, i design the circuit of relay that suitable to use in my project.

Figure above show that my relay circuit after make some editing and correction about symbol and also proper design 

WEEK 13

Title : Schematic Diagrams

For this week i design the schematic diagram for my pic circuit, from the figure show that all basic component that pic circuit require which is oscillator circuit, the grounding circuit and also the power supply circuit that require to complete the basic of PIC circuit.

WEEK 12

Title : Draw Schematic Diagrams

 Figure 1: Bluetooth Module Diagram

Figure 2: Voltage Regulator Diagram

            For this week i'm have make some research about my schematic diagrams for my project, as u can see at figure 1, this will my Bluetooth Module connection and also the value of resistor that will connect to this circuit and also the voltage value take Bluetooth Module require which is 3.3V. 

           To get the require voltage value which is 3.3V the circuit need the voltage regulator to produce that require voltage value and the figure 2 show how the circuit from voltage regulator (LM 317) connection to produce the require voltage value   

WEEK 11

Title :  DISCUSSIN WITH STUDENTS FYP2

This is how my friend project look like, he use bluetooth module to control the parking system and this already done and test the circuit and it was 100% working nicely.

This is how bluetooth module look like, this is bluetooth module connection circuit, my friend explain to me about this connection and he told me that bluetooth have primary and also slave that fuction as transmit and receive the data and all of that was already install in the bluetooth module.
