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.

WEEK ELEVEN
after we purchased the component we started to put the component on the test board
on the test board the left side is high low beam auto switch and right side is fog light flash.
after the test board is ready and put the power on and bulbs to test, in fact the high low beam is one pair and fog light is pair, but we use the one bulb to test.
and using the LED light to be a light source for high and low beam.

WEEK TEN
Purchasing component:
we purchasing some component for the test board.
The parts supplier is jaycar. the total price is around 33 NZD.

week night
multisim drawing for the fog light and high low beam is done.
however the picture for the Multisim is hard to put on the blogger,
so we just took a photo by the camera and than transfer the picture from the camrea
to the computer.
By the Multisim did not have the LDR light independent resistor, so we just used a
variable resistor to instead of it.
and later we turn on the light on the multisim the system is working.
