Week six technology project

Hi every one:



I and buddhika found the circuit problem was on the part (transistor and bulb).



The design using the transistor to be switch for the bulb is quite hard, because the high current and voltage, later we talked with the tutor about it. we can us a relay to control for the bulb, and the a small relay for the switch for the relay.

That is a new design, but we need to do it by the test.
