Software Setup You should do the following things before the class:

Install Arduino IDE if you don't already have it, and upgrade to something recent if you're below version 1.7 - http://arduino.cc

  • In Boards Manager, add ESP8266 Board support

Set up a Cayenne account - https://cayenne.mydevices.com

Install the following libraries:

Modify BME280 library

  • on OS X, navigate using the finder or otherwise cd ~/Documents/Arduino/libraries/Adafruit_BME280_Library-master/
    • On Windows & Linux the files will be somewhere similar.
  • edit Adafruit_BME280.h using your favorite editor- change #define BME280_ADDRESS from 0x77 to 0x76
  • more advanced C programmers may do something like:
#define BME280_ADDRESS 0x77
#ifdef CLASS_BME280 
#define BME280_ADDRESS 0x76
#endif

and then add #define CLASS_BME280 at the beginning of your program, so that way if you get an Adafruit BME280 board in the future, it will continue to work right…

Hardware Construction
  • On the programming board, wire an SPST or SPDT switch between GPIO and GND
  • If you plan on re-using the boards for something else in the future, solder in header pins on the other boards. If you're building this as a

If you want to re-use the component boards for other projects

Software Programming

Power considerations The kit does not come with a power source. The regulator board requires at least 4.5V (and at most 15V!) to adequately supply 3.3V to the ESP8266 and BME280 boards. A 9V battery or 6V AA case should work
