+## What is Arduino?
+
+<Missing Arduino graphic>
+
+It's a kit (on a board) with the bare minimum components to easily use the $\mu$C
+hardware. They do the basic, boring design needed for any board, so users only
+need to add the neat stuff.
+
+## Arduino Software
+
+The Arduino folks also adapted an *Integrated Development Environment*
+(IDE) to their boards. This IDE allows us to easily write programs for
+their boards and then write the programs to the $\mu$C.
+

+
+# Circuit Basics
+
+## Current
+
+Current is the flow of charge through a circuit. Measured in Amperes
+(\si{\ampere}).
+
+## Resistance / Impedance
+
+Circuits have a resistance to current flow that depends on the parts
+in the circuit.
+
+Measured in Ohms (\si{\ohm})
+
+## Voltage
+
+Voltage is a potential (akin to a pressure) pushing the current
+through a circuit. Current is said to flow from higher (+) voltage
+to lower (-) voltage.
+
+Measured in Volts (\si{\volt})
+
+## Ohm's Law; Light
+
+Voltage, Current and Resistance are related to each other.
+
+- As voltage increases, current increases
+- As voltage decreases, current decreases
+- As resistance increases, current decreases
+- As resistance decreases, current increases
+
+## \si{\volt},  \si{\ohm}, \si{\ampere}: The Water Analogy
+
+If charge were water, then:
+
+  - resistance = obstacles blocking flow
+  - current = flow rate
+  - voltage = change in height *or* pressure.

+## Buttons
+
+- Buttons connect _or_ disconnect two wires/parts
+- Momentary Switch: Normally Closed (NC), Normally Open (NO)
+- Toggle Switch
+
+## Circuits
+
+A circuit is a completed loop from HIGH potential (voltage) to LOW,
+which causes current to flow through some other components along the
+way.
+
+## Transducers {.fragile}
+
+Often these *other* components are *transducers*, which convert
+electrical energy into another sort of energy:
+
+| |
+-------|--------:
+Speaker|Electrical $\rightarrow$ Sound
+Microphone|Sound $\rightarrow$ Electrical
+LED|Electrical $\rightarrow$ Light
+LED|Light $\rightarrow$ Electrical
+Piezoelectric|Electrical $\rightarrow$ Motion
+
+<!-- ## Piezo Buzzer -->
+
+<!-- - Piezoelectric elements change shape when voltage is applied -->
+<!-- - Thin discs can be made to oscillate and create sound. -->
+<!-- - Contains oscillator circuit -->
+<!-- - Two connections: Vcc, GND -->
+<!-- - Use a switch; connected = annoying tone, disconnected = glorious silence -->
+
+## Power
+
+The power supply provides the energy to drive the system.
+
+Can be a:
+
+* Voltage Regulator (converts one potential to another)
+* Batteries
+* Solar Panel
+
+In our circuits, your laptop is converting it's power source to $\SI{5}{\volt}$ and
+delivering power to our circuit via USB.
+
+## $\mu$Controller
+
+Microcontroller ($\mu$C) is a *processor*, *memory* and a few *peripherals* on a standalone
+chip.
+
+Processor
+:    is a group of transistors that understands a dozen or so
+commands (ADD, SUB, JUMP..)
+
+Memory
+:    a circuit that can hold values.
+
+Peripherals
+:    Vary chip to chip, but often include timers, communications and
+ADC, DAC.
+
+Seems complicated, but really simple. They read a command from the
+start of memory, then execute the command. At the end of the command,
+read the next command from the next memory cell and
+repeat^[some commands change the address of the next fetched command]
+
+## Digital Signals
+
+- Vcc: The power supply of the circuit elements
+- GND: The reference voltage (usually \SI{0}{\volt})
+- Connecting a part to Vcc = Logical 1 or High
+- Connecting to GND = Logical 0 or Low
+- Connecting various pins to Vcc or Ground is all the $\mu$C can do to
+  talk to the world [^4]
+
+[^4]: w/o fancy peripherals or dirty tricks
+
+## $\mu$Controller INPUT and OUTPUT
+
+Most of the pins on the Arduino can be set for INPUT or OUTPUT mode.
+
+- INPUT mode pins listen for a signal ($0$ or $1$) from another device
+- OUTPUT mode pins drive the pin High or Low
+
+## Floating Pins
+
+What's happens if an INPUT mode pin tries to read the value of a pin
+that is connected to nothing? Is that a $1$ or $0$?
+
+\center{\huge {No one knows!}}
+
+It's dependant of transient charges, static, nearby electric fields,
+the phase of the moon, \ldots Whenever you want to check a digital
+signal, make sure that something is *driving* it (ensuring Vcc or GND).
+
+## $\mu$C + Digital Signals as Switches
+
+If one end of an LED is connected to ground, and the other end is
+connected to an OUTPUT pin on a $\mu$Controller, then:
+
+- If the $\mu$C sets the pin High (Vcc, $\SI{5}{\volt}$) then current
+will flow from the pin through the LED and turn it on.
+- If $\mu$C sets the pin Low (GND, $\SI{0}{\volt}$) then the current
+will not flow and the LED is off.
+

+\end{center}
+
+## Your first Program
+
+~~~ C
+#define LED 13
+
+/* the setup function runs once on reset / power */
+void setup() {
+  pinMode(LED, OUTPUT);
+}
+
+/* loop() repeats until reset or power off */
+void loop() {
+  digitalWrite(LED, HIGH);   // turn on LED
+  delay(1000);              // wait for a second

+# Add Some Parts
+
+## Breadboard
+
+![Breadboard](images/breadboard.png)\
+
+- Connectors gently pinch component leads, wires.
+- Have internal connections
+
+## Power Up the Rails
+
+We use the long rows to distribute power. The Arduino outputs
+$\SI{5}{\volt}$ on the pin marked `5V`, the reference (GND) is marked
+`GND`.

+## Push Button: Zoom
+
+\begin{center}
+\includegraphics[width=0.98\textwidth]{images/bb+switch+zoom.png}
+\end{center}
+
+## Pullup / Pulldown Resistors
+
+Reading a floating pin is **bad**. A switch only connects
+and disconnects a wire. When the wire is disconnected... the INPUT pin
+is floating!
+
+\vfill
+
+**Solution:**
+
+Connect the pin to Vcc so that it reads High; use a
+resistor to prevent short circuit (limit current).
+
+## Buzzer: Zoom
+
+\begin{center}
+\includegraphics[width=0.98\textwidth]{images/buzzer-zoom.png}
+\end{center}
+
+## Buzzer / Button: Software (Part 1)
+
+~~~ C
+#define BUTTON 2
+#define BUZZER 8
+
+int button_state;
+
+void setup() {
+  pinMode(BUTTON, INPUT);
+  pinMode(BUZZER, OUTPUT);
+  digitalWrite(BUZZER, LOW); /* Start w/ LED off */
+}
+~~~
+## Programming Note: Variables
+
+Declare a variable:
+
+~~~ C
+int button_state = HIGH;
+~~~
+
+`<type> <name> [= <initial value>];` (value optional)
+
+It's a name, like a preprocessor `#define`, but the value can change
+at *runtime*
+
+## Programming Note: *If* Statement
+
+~~~ C
+if (condition) {
+	// body: Runs if condition true ( != 0)
+} else {
+	// Runs if condition false ( == 0 )
+}
+~~~
+
+ - body code inside curly braces: `{` `}`
+ - **condition** evaluates to 0 $\rightarrow$ body code skipped
+ - else section is optional, runs if **condition** evaluates to 0
+ - **condition** evaluates to *not* 0 $\rightarrow$ body code runs
+
+## Programming Note: `==`
+
+In C-like languages, the `==` operator checks if two things
+(statements, variables, \ldots) are equal to each other.
+
+ - It returns `1` if the items are equal, *or*
+ - It returns `0` if the items are not equal
+
+## Programming Note: Functions
+
+Functions make it easy to reuse code. You already know / use several
+functions:
+
+ - pinMode
+ - digitalWrite
+ - delay
+
+digitalRead(pin number) returns HIGH or LOW depending on current state
+of any **INPUT** pin.
+
+You can write your own functions!
+
+## Programming Note: Writing Functions
+
+~~~ C
+void my_function(int arg1, ...) {
+	// Do fun things
+}
+~~~
+
+void:
+: Return type. Void means nothing returned. Can be any type.
+
+my_function:
+: A name for your function
+
+arguments:
+: A type and name for any parameters you want to use in your function
+from the outside.
+
+Define a function once, you can use it again and again. Better than
+copy/pasting.
+
+
+
+## Push Button: Software (Part 2)
+
+~~~ C
+void buzz(int ms) {
+	digitalWrite(BUZZER, HIGH);
+	delay(ms);
+	digitalWrite(BUZZER, LOW);
+}
+void loop() {
+  button_state = digitalRead(BUTTON);
+  if (button_state == LOW) {
+	buzz(100);
+  }
+}
+~~~
+
+# More Parts
+
+## Potentiometer
+
+*Puh - ten - she - ometer*
+
+- *Pot* for short
+- A Voltage Divider
+- Voltage at *Wiper* is somewhere between potential at the two
+  terminals.
+- The exact wiper potential depends on the position of the knob/lever.
+
+## ADC: Analog to Digital Converter
+
+- A peripheral of the $\mu$Controller
+- Measures Potential, outputs a number
+- In our case, $\SI{0}{\volt}\rightarrow0$ and
+  $\SI{5}{\volt}\rightarrow1023$
+- A0-A5 pins on Arduino can be used
+- Fun uses: Reading pot position, sampling audio, reading from sensors
+
+## The Pot Hookup
+
+\begin{center}
+\includegraphics[width=0.98\textwidth]{images/bb+switch+pot.png}
+\end{center}
+
+Connect center pin to `A0`, outer pins to ($+$) and ($-$) rails
+
+## Pot Code
+
+`analogRead(`*pin*`)` returns the voltage at the pin (0--1023), it can
+be used directly or via variable.
+
+~~~ C
+#define LED 13
+void setup() {
+  pinMode(LED, OUTPUT);
+}
+void loop() {
+  digitalWrite(LED, HIGH);
+  delay(analogRead(A0));
+  digitalWrite(LED, LOW);
+  delay(analogRead(A0));
+}
+~~~
+
+Since the delay() calls use the result of analogRead (0-1023), the
+blink rate changes with knob position.
+
+# Shall we play a game?
+
+## Hooking up a bunch of LEDs
+
+\begin{center}
+\includegraphics[width=0.65\textwidth]{images/bb+switch+pot+leds.png}
+\end{center}
+
+## LEDs, the first one
+
+Looks complicated, but for each LED: The short leg goes to ground, the
+long leg goes to one end of a resistor, and the other end of the
+resistor goes to the arduino pin.

+# The End?
+
+# Extra Credit
+## Ohm's Law
+
+Ohm's Law relates current to potential and resistance.
+
+$$ V = IR $$
+$$ I=\frac{V}{R} $$
+$$ R = \frac{V}{I} $$
+
+* V = Potential in Volts (\si{\volt})
+* I = Current in Amperes (\si{\ampere})
+* R = Resistance in Ohms (\si{\ohm})
+
+## Ohm's Law: Example
+
+The datasheet for an LED says that the maximum continuous current is
+\SI{15}{\milli\ampere}. Your circuit operates at \SI{5}{\volt}\footnotemark[1]. How
+big should your resistor be?
+
+$$ \si{\ohm} = \frac{\SI{5}{\volt}}{\SI{0.015}{\ampere}} = 333.\overline{3}\si{\ohm} $$
+
+How much current for our *cheet sheet* value?
+
+$$ \si{\ampere} = \frac{\SI{5}{\volt}}{\SI{1}{\kilo\ohm}} = \SI{5}{\milli\ampere} $$
+
+\footnotetext[1]{\tiny Actually, this calculation is inaccurate. LEDs
+will have a *forward voltage drop* of between \SI{1.8}{\volt} and
+\SI{3.3}{\volt} this should be subtracted from \si{\volt} above... but
+it's not critical.}
+
+## Current Limits, Arduino
+
+- No single pin should source more that \SI{20}{\milli\ampere} (\SI{40}{\milli\ampere} is absolute max)
+- Pins are ganged together in groups of 8, no group should source more
+  than \SI{150}{\milli\ampere} total
+- The whole board cannot source more than \SI{200}{\milli\ampere} total
+
+Practically speaking, this means that the Arduino cannot drive
+speakers, most motors, or anything normally mains powered.
+
+## So\ldots no Arduino smart blender?
+
+You can control almost anything with an arduino, you just can't power
+it with the Arduino. There are various devices that let you switch
+highier powered devices:
+
+ - Transistors
+ - Relays
+ - Solid State Relays
+ - Triac
+
+## HIGHs and LOWs
+
+Many different logic levels are in common use: \SI{1.2}{\volt},
+\SI{1.8}{\volt}, \SI{2.5}{\volt}, \SI{3.3}{\volt}, and
+\SI{5}{\volt}. The voltage cited is the *nominal* Vcc of the system.
+
+A HIGH signal is generally any voltage $\geq \frac{2}{3}V_{cc}$.
+
+A LOW signal is generally any voltage $\leq \frac{1}{3}V_{cc}$.
+
+## HIGHs and LOWs, pt. 2
+
+In your travels, you're likely to see both \SI{5}{\volt} and
+\SI{3.3}{\volt} sensors and peripherals.
+
+Since $\SI{3.3}{\volt}\geq\frac{2}{3}V_cc$ your Arduino will accept
+input from a \SI{3.3}{\volt} peripheral without issue.
+
+If you drive an output to \SI{5}{\volt} while it's connected to a
+\SI{3.3}{\volt} peripheral with an Arduino **it will blow up your
+peripheral**.^[In the datasheet for the sensor, it'll have a
+section called *Absolute Maximums*. Generally \SI{3.3}{\volt} parts
+won't accept more that $\approx\SI{3.6}{\volt}$, but some will.]
+
+## HIGHs and LOWs, pt. 3
+
+Solutions:
+
+ - Level Shifter: A dedicated chip that translates between
+   voltages. Available as uni or bidirectional.
+
+ - Buy a 3.3V Arduino Compatible. Arduinos are available that operate
+   at the lower voltage.
