This is my first project using an Arduino Uno as well as posting it on Instructables. I will do my best to make this instructable as clear and and to the point as possible.
I wanted to take a household object and add a temperature and LED sensor that would change the brightness of the LEDs as the temperature in the room changes.
To start here is a list of supplies I used:
Blank circuit board for final product Link:amazon.com
Solid Core Wire Link:amazon.com Its a good idea to use different colors for the Ground Wire (negative and commonly marked by black wire) and the Positive Wire (marked with red wire).
Breadboard(optional) Link:adafruit.com A breadboard is used for testing a circuit without the need for soldering.
Glass Jar Link:hobbylobby.com
Spray Paint Link:lowes.com Used to frost over the glass jar
Now for the more important components.
Multimeter Link:amazon.com Very useful tool, used for lots of different task a few being; testing to make sure your connection is getting power, can read the value of resistors and read the voltage left in a 9v battery and much more.
DHT22 Temperature/Humidity Sensor Link:adafruit.com I choose not to implement humidity in this project however you can have the LEDs change as the humidity changes the same way as they do for the temperature, which will be explained in the code later on. Adafruit also sells a wired sensor with a resistor built in. I originally used that sensor but ran into overheating issues.
