Arduino

Arduino is an open-source physical computing platform designed to make experimenting with electronics more fun and intuitive. Arduino has its own unique, simplified programming language, a vast support network, and thousands of potential uses, making it the perfect platform for both beginner and advanced DIY enthusiasts.

Circuit 1: Blinking LED

The original code without changes

Blinking once per second and holding for .15 of a second.

Circuit 2: Potentiometer

As you turn the potentiometer it makes the led flash faster or slower.

How does the Potentiometer work?

A potentiometer works by having a metal wiper move along a track between a wiper terminal and a output terminal. Increasing and decreasing resistance as it moves.

Circuit 3: RGB LED

When showspecturm is by itself it makes it where the light never stops

Circuit with no code changes.

To get show(spectrum) only you have to turn the mainColors into a note so it does not do anything anymore. It causes the light to never turn off

Circuit 4: Multiple LEDs

OnAfterAnotherNoLoop makes it where it makes the LEDs go one after another and come back

randomLED make it where a random led comes on and there is no special pattern to when the LEDs turn on

Circuit 5: Push Buttons

When you push the button it gives power to the LED to light up

Circuit 6: Photo Resistor

Manual Tune

Manual tune makes it where you have to switch the range of brightness to see when it turns on or off

Auto Tune

Autotune makes it where the arduino board sets the range for you and you dont have to do anything special in the code yourself

Pros and Cons of both functions

The pros of autotune are that you dont have to switch the range ever

The cons of autotune are that it is very reactive and it switches to everything

Circuit 7: Temperature Sensor

At first this circuit was just the temperature sensor but it was then coded to work with an LED for when it got to a certain temerature the light would turn on.
