IEEE IoT June 4, 2016

COURSE MATERIALS ARE UP TO DATE AS OF 6/9/2016.

• Arduino Sketches
  • All course Arduino sketches are in one zip archive.
  • After download, extract the files. Copy the extracted folders to your Arduino Sketchbook folder. This is usually Documents/Arduino. If you are not sure, run the Arduino IDE and open menu item File | Preferences. The first item on the dialog is “Sketchbook location”.
    • IEEE_IoT_Sketches_2016-06-06
      • IEEE_IoT_Sketch01_Blink – blinks the onboard LED
      • IEEE_IoT_Sketch02_Hello_World – displays a message on the LCD
      • IEEE IoT_Sketch03 – Standalone Weather Station – displays sensor data on the LCD and serial monitor
      • IEEE IoT_Sketch04 – IoT Weather Station – sends data to a ThingSpeak channel – version 6/6/16 – removes WiFi_Sta mode
      • IEEE_IoT_Sketch05_Smartphone – uses the SimpleTimer and Blynk libraries to send and receive data from a smartphone app – version 6/6/16 – removes WiFi_Sta mode, adds links to libraries
      • IEEE_IoT_I2C_Scanner – scans I2C bus to find addresses of all connected devices. Use this if you do not know the address of the LCD.
• Library files. Instructions for installation are included in the course slides.
  • SparkFun_HTU21D_Library– also at https://github.com/sparkfun/HTU21D_Breakout
  • Arduino-LiquidCrystal-I2C-Library – also at https://github.com/fdebrabander/Arduino-LiquidCrystal-I2C-library
  • Adafruit_BMP085_Modified – adds keywords.txt to Adafruit distribution
  • SimpleTimer – used only in Sketch05 to schedule reporting tasks to Blynk and ThingSpeak. Download the zip file from https://github.com/schinken/SimpleTimer
• Handout (includes NodeMCU pinout, parts list, and resource links)
• ThingSpeak Scripts – paste these text file scripts into blank ThingSpeak MATLAB Visualizations. See the tutorial at https://www.mathworks.com/help/thingspeak/matlab-visualizations-app.html
  • Dewpoint_in_Fahrenheit – chart shows temperature and dewpoint in Fahrenheit. Dewpoint is calculated from temperature and humidity and is the temperature at which condensate will form on a surface.
  • Display_Multiple_Channels – displays one field from each of four channels.
  • Temperature_Correlation – provides a linear curve fit between temperatures measured by the BMP180 and HTU21D sensors.
  • Google_Gauge_JavaScript – instructions at http://community.thingspeak.com/tutorials/google/display-a-google-gauge-visualization-using-thingspeak-plugins/. Note: this works only on your Private view.
