This project uses WIFI, but cannot connect through FIU Secure WIFI. The NodeMCU code is not suitable for WPA2 Enterprise. Use your router at home or a hot spot through your cell phone.

Modules:

The project has four weeks of Modules. The schedule and score percentages are in the Syllabus. The submission scores count toward the final grade in this course. Assignment are submitted through the form on the class web site which has drop down list options for the Modules.

ML1: MQTT Lesson One - ArduinoIDE

• Order the parts

• Install the Arduino IDE

• Download .ino code for Arduino Sketch for push button example

• Compile the Sketch (upload and try on board once arrived)

ML2: MQTT Lesson Two -Virtual

• Download the .ino code for the Module Sketch

• Register as a user with Losant

• Create a Device

• Set the Device Attributes

• Download the credentials

• Insert credentials in code to enable log in

• Compile and upload code to the NodeMCU

• Run the code on the NodeMCU - Serial Monitor for internet connection and log

• Push the NodeMCU button and watch the Losant Device Log for event

• Create the Workflow with Virtual Button - press and toggle the NodeMCU LED

ML3: MQTT Lesson Three - DHT22

• Connect the DHT22 to the NodeMCU

• Download .ino code for the Module Sketch

• Compile and upload code to the NodeMCU

• Print Temperature and Humidity locally on the Serial Monitor

ML4: MQTT Lesson Four - Dashboard

• Losant - create another new device for temp/humidity

• set Device Attributes for temp & humidity

• Download credentials

• Download .ino code for Module Sketch

• Insert credentials into code to enable log in

• Compile and upload code to the NodeMCU

• Run the code on the NodeMCU - Serial Monitor for internet connection and log

• Confirm communication from Device log

• Create a Dashboard

• Add Guage and Trend Plot components to show Temperature and Humidity

• Get URL to share the Dashboard and leave connected for assignment submission
