== Getting Started ==
If you have never worked with an Arduino before, you'll first need to install the Arduino IDE (Integrated Development Environment).

=== Download and install the Arduino IDE ===
Windows: https://www.arduino.cc/en/Guide/Windows
Mac OS X: https://www.arduino.cc/en/Guide/MacOSX
Linux: https://www.arduino.cc/en/Guide/Linux
Web IDE: https://create.arduino.cc/editor
You may need to install a separate USB driver to connect with the Arduino board. Speak with one of us.

=== Arduino Pinout ===

==== Test that your setup works - Blink the Arduino's onboard LED ====
Select "Blink from the Arduino IDE's "File > Examples > 01. Basics" menu, or load the code from the following page:
https://www.arduino.cc/en/Tutorial/Blink

== Fun with LEDs ==

=== Let's add one LED to your Arduino breadboard now, and make it blink ===
You can either modify the "Blink" example above to use a different pin, or you can follow another example sketch-

=== Blink without the "delay()" function ===
A slightly more sophisticated technique- load File > Examples > 02. Digital > BlinkWithoutDelay

=== PWM: Pulse-width modulation ===
Use a digital "~" pin to output a signal which dims and brightens using pulse-width modulation (powering the pin for short bursts)
Load File > Examples > 03. Analog > Fading

=== Multiple LEDs at once ===
Now let's add multiple LEDs to your breadboard, and make them blink-

=== Controlling LEDs with Outside Events ===
Adding inputs to control the LEDs: switches

=== Use a Photoresistor to control an LED! ===
See Kevin for a photoresistor. Follow these directions to set up the photoresistor, then use the input to control the PWM from above.

== Intermediate ==

=== Communicating between two Arduinos with Packet Radios ===
Packet Radios! The nRF24L01 is a digital radio chip that Arduinos can use to send and receive data.

Requires two people with an Arduino apiece. Ask Kevin, J, Asim or Joe for a radio module.

== Advanced ==

=== Packet Radios^2! Communicate with more than one other radio ===
Send an ACK (acknowledgement) message after receiving a message. Let's sender know a receiver got a message.
This constitutes bidirectional communication, which
