8. Not just a computer – a platform
Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software.
It's intended for artists, designers, hobbyists and anyone interested in creating interactive objects or environments.

15. Arduino Development Environment
Text Editor - to write and modify sketches
Verify – checks for errors
Upload – loads code into Arduino board
New – creates a new sketch
Open – get sketches from sketchbook
Save – saves your sketch
Serial Monitor – opens up a realtime communications port to your Arduino board

19. 10 |Ways to Kill an Arduino*
Quick Links:
Method #1: Shorting I/O Pins to Ground
Method #2: Shorting I/O Pins to Each Other
Method #3: Apply Overvoltage to I/O Pins
Method #4: Apply External Vin Power Backwards
Method #5: Apply >5V to the 5V Connector Pin
Method #6: Apply >3.3V to the 3.3V Connector Pin
Method #7: Short Vin to GND
Method #8: Apply 5V External Power with Vin Load
Method #9: Apply >13V to Reset Pin
Method #10: Exceed Total Microcontroller Current

Let’s Do Something!
Get connected up
USB cable
Power source
Run arduino.exe
Configure board (Uno)
Serial Port (usually COM4 for USB)
Load “blink”
Upload blink
Modify blink
Run again

23. (c) Rick Darby 2013. All rights reserved.
Digital Inputs
Input: Sketch 6_02 and 3 wires
Wire D5 to your finger
Wire D5 to +5V
Wire D5 to GND
Debouncing: Sketch 6_04
(c) Rick Darby All rights reserved.

24. (c) Rick Darby 2013. All rights reserved.
Digital Outputs
Upload Sketch 6_01
Modify int outPin = 4; to int outPin = 13;
Run
Open Serial monitor
Enter 1 and then 0 from laptop

25. (c) Rick Darby 2013. All rights reserved.
Sound
Example 2.
Connect red lead of piezo to D9
Connect black lead of piezo to GND
Copy code into Arduino editor
Save and Upload
(If no piezo, use 1K resistor in series for 8 ohm speaker)
(c) Rick Darby All rights reserved.

26. Reading Analog Signals
Output: Sketch 6_09 and 1 wire
Wire A0 to +5V, ck Serial Monitor, then disconnect
Wire A0 to GND, ck Serial Monitor, then disconnect
Wire A0 to 3.3V, ck Serial Monitor, then disconnect
3 Wires and potentiometer

Using a Serial LCD
Do NOT run this on USB power only: connect 9V power!
Attach pot as in
Test that pot is being read correctly
Download AnalogSerPrtQS.ino from uploads section
Use breadboard and jumpers
LCD red lead is +5V
LCD black lead is GND
LCD yellow is D2
