LDR

 The work was to turn on the light bulb when it was night and turn it off when it was day.

To achieve this goal we use a LDR(Light dependent resistor)

Car


1.Materials:

-1 motor
-Battery
-1 limit swich
-1 swich
-Wood
-Cardboard
-Plastic wheels
-1 relay

2.How does it work?


                                         When the car meets an obstacle or barrier, 
                                  the wooden piece moves and makes 
                                      contact with the limit swich,wich sends
        a signal to the relay.
                                        When the metal piece of the relay moves,
                                          and thanks to the battery, the motor makes
                                         the wheels change the direction of the car


             3.How we made the project

    First of all, we cut the pieces of wood fllowing the
                                                             design we did. When we finished them, we continued joining
                                                               them with glue, and we screwed the components of the circuit.
                                                        Then we sticked the components to the base and weld the 
                                                            axes of the wheels. The bodywork is made of red cardboard
               and wheels are made of plastic.

Production, transport, consumption.


The idea of the work was to produce, transport and consume electricity in someway, so we form three groups in the class.
I was in the part of transport the electricity. Within each group, each member of the group did his own work.

My part was to make the towers to carry electricity.
 We did the tower with chopsticks and then we painted them.

hey, what's going here?

Hi! here I am, this is my new blog for the technology class, so I will post my works or everything releated with technology. See you!
