Daily Progress for project KKKL 2092 Electrical and Electronic Lab II

Day-14( 17 October 2010)

Finally, we print out our report with 8 pages. We will pass it up to our coordinator, Dr. Norhana on Monday. Start to do the slideshow for the Wednesday presentation.

Below are some of the contents of our journal:

OBJECTIVE:

a) To recognize the functionality of each components given.

b) Construct a white line follower toy car.

c) To determine the application of the white line follower in our real life.

PROBLEM STATEMENT

For the analogue mini project, we are assigned to make a white line follower. All the components like light dependent resistor (LDR), resistors, transistors, capacitors and motors are provided .Therefore we need to know the functionality of each component given to ensure the circuit is built successfully. Besides that, we also need to do some researches on the application of the white line follower in the household appliances that makes the human life become better.

Day-13: (16 October 2010)

- Go to Times Square today to find the 4 tyres for the toy car. Fail to find the saiz of tyres that suit the toy car.

-Replace a 5k potentiometer with a 2k potentiometer. Have to test the new circuit again on Monday for the new components.

-Continue doing the report that need to be submit. Fail to find many useful information about the white line follower toy car. So, we have to elaborate the points based of our concept and understanding.

Day-12: (15 October 2010)

Start and do the report for our circuit. We divide our job fairly. Recheck the components using the multimeter and reconstruct the circuit.

Day 11: ( 14 October 2010)

We start to do our report. Testing the circuit again. The circuit cannot function today. The servo motor not steer to left or right side when one the LDR is being blocked. One of the capacitor is spoilt due to over-voltage today. Planning to do some changes to make the circuit to function again.

Day 10:(13 October 2010)

Reconstruct the circuit.

Do the check up for circuit with partner.

Change some error position of components that we placed it yesterday.

Finally, we managed to make the circuit work using the voltage from IDL. The motors work and the servo motor manage to change the direction of toy car when we block the light for LDR.

But the circuit not works when we use two 3V battery source. Still need to do some improvements and the error analysis.

Day 9:( 12 October 2010)

-Construct the circuit according to diagram at the lab.

-Testing the circuit but it failed to work.

-Arrange the circuit nicely.

-Cut down the leg of components to make the circuit board nicer looking.

From 10:30-12:30p.m, we started to put the circuits into place. With the circuit diagram given, we used some of the tools that was handed to us and most of them that we have bought from Jalan Pasar. The only difficult part was putting the circuits into the correct position because there were many corrections and we had to be careful to avoid short circuit. Only one confusing part which was the potentiometer. There were 3 connecting wires which was the collector, base, and emitter terminal and three of those wire had different colors. Moreover, when it comes to the motor, we used a toy car to make the project work. We only needed to solder the wire from the circuit onto the motor.After that is completed, we continued on checking the circuit and troubleshoot was conducted. We stopped here and decided to continue the following day.

Setting up the circuit at the early stage.

Separated the materials for a better working environment

Our toy car that will be used to follow the white line

Day 4,5,6,7(7-10 October 2010):

No progress. Busy with college activity and co-curricular activity.Get the wires from lab.

Day-8:(11 October 2010):

Get the toy car.Go to Jalan Pasar Pudu to buy the electrical components and circuit board. Starting to connect the circuit according to the diagram.

Day 3( 6/10/10):

-Try and simulate the circuit using Circuit Maker software.

-Fail to simulate it because I cannot find the servo motor in this software.

-So, we only can focus our mind on simulate the circuit using the actual components in the lab. We have to detect all the problems exist in this circuit ourselves.

Day 1(4-10-10):

-Prepare a list for equipments and electronic components for the project.

-Understand the construction of circuit and find some relevant information about the white line follower.
