4-11

: This morning we made a combination lock with arduino, also a breadboard and an LED
: Technically we didn't make a combination lock we just used a 4 position toggle switch
: A 4 position toggle switch is a box switch with 4 little triggers/switches on it
: We used this switch to light up the LED
: If switches 1 & 2 were pushed up then the LED would turn on
: We could have also changed it so that another 2 switches would turn on the LED

: This afternoon we worked in groups again
: We continued working on the tree guard design challenge
: This time we had to make scaled models with our tree guards included
: I kind of figured my tree guard wouldn't work so I used a regular box shaped tree guard
: Paul helped with this challenge
