- In the morning we work on the arduino to make combination lock to make the led light up.
- We used a dip switch for this process and a breadboard , some wire and a arduino.
- The first step was to put the dip switch in the breadboard and hook it up to power it.
- the second step was hoking the dip switch to the arduino and a pulldown resistor, then we hook up the wires to the pins on the arduino. i picked 2,3,4,5.
- Then last we had to create out code so that when we pulled the switches up the led would turn on .
This is the code we made.
/*
Button
Turns on and off a light emitting diode(LED) connected to digital
pin 13, when pressing a pushbutton attached to pin 7.
The circuit:
* LED attached from pin 13 to ground
* pushbutton attached to pin 2 from +5V
* 10K resistor attached to pin 2 from ground
* Note: on most Arduinos there is already an LED on the board
attached to pin 13.

- In the afternoon we again worked on out models for the tree guards.
- I did not have a model so i had to sketch ideas of what i want my tree guard to look like.
- I then made three models , one with just a cube shape tree guard, the other with just a box shape , and the last one looked like a crown.
- I had picked the crown shape one that i would put some type of wire on the top that puts the crown shape boards together and circles around the tree.
- Next class i have to laser cut it out and put it together and put it around a tree model we have made and then our tree models will be done.
