In this unit we learned how to code. Coding is computer language. It is like you wright something on the computer and it dose it. It is like instructions. For example, Gates to go in and out. when you put your card in reads it and lets you in. There are scanners on the sides so no one can sneak in behind you.
In school we learned how to code. To code we went to a site named Scratch. On that site you can code games. I coded one called Super Dog! To code it I had to use blokes to make a sequence.
This year we made a prototype that will save energy by unplugging the computer. I liked being an engineer because we got to design with the humming bird. I thought it was challenging when we plugged it in and it went wanky. So we tried a new plugin and it worked. First we used a motor but it did not work so then we used a servo!
