after we finished the garage test, we start to prepare the presentation.
I and buddhika did the presentation before the due day, and I did one time in the 108 building and Vijay is our tutor and listen and see our presentation and gave us some suggestion, and we accepted and modify our presentation.
The next day for real presentation, we did good.
and the tutor sasked us some questions, we answer some of them, and left ones we answered on the our writing report.
Thanks every one.
Thanks Anura to be our tutor
Thanks Vijay gave us lot of help for the project
Thanks Niranjan to give us two time postpone the due day for the writting report.

Week 17 garage test 2
when we test the showing aboard on the morning however the system did not work,
the reason is the light on the morning is quite bright, so the sensor is not good for day light.
so we changed to the night, and shut down all the light.
start the engine
turning on the high beam, and showing board is low beam and fog light.
The fog light on the showing board is flash.
Turning on the low beam,and showing board is high beam.
when the showing board is capturing the low beam from the vehicle, the high beam shift to the low beam.
because the garage is too short, so between the vehicle and the showing board the distance only has ten meter.

Week 16 garage test
Although we used the LED torch to test the showing board on the lab.
We need to test the board in the garage under the dark light, because we want to see what will happen, is it working properly?
First we measure vehilce bonnet the distance from the ground, and then put the showing board in the same height.
Parking the vehicle in the longer distance and turning on the head light.

Week 15 showing board 2
when we put all part on the showing board, we need to connect the wire.
after connect the wire and power supply than start to test
after the test on the board is successfully we start to solder the wire.
and then test on the garage.
Weeek 14 showing board first steps
after we did the ciruit picture drawing and Multsim and test on board, we decided to make a showing board.
(1) for the presentation
(2) assignment (in what of kind condition the circuit works)
prepare the matarial, parts , wiring, etc

WEEK 13 problem solved
we check every thing, later we talked with our tutor the problem is coming the transistor.
we need to use the BC 547 to contro the relay and use the relay to load the bulb.
in the circuit you need the relay to load the bulb, because the high current, which will reach to 1A to 5A or evern more the transistor can not hand it.
after we use the transistor BC547 and the relay, the circuit is working.

WEEK TWELVE PROBLEM
During the test we found one problem:
That is coming from the FOG LIGHT,
We used a transistor 2N3055
To load and control the fog light, it's not working.
