Server Notes

A $9.99 Udemy course finally connected the last dots that enabled me to build my own IoT server! On the first link above, I used the free SMQ server, SimpleMQ. But the free version is limited to just on/off switches. Well, I saw I could hack it and use other controls - and I don't have a problem with that for personal use - but I draw the line at documenting how to build the server by hacking their site.
On Udemy, I found a – still under construction – “Build a Scalable Big Data IOT Web Application From Scratch” course by Jeff Katchinska. That had the piece I was missing, the PHP code to interface with the mySQL database.
The completed Arduino project, built on an ESP8266 uses an analog to digital converter to send a voltage reading - that is set with the blue trim-pot - to an online database when you press the button. The web page displays the data from the most recent data in the database. Pretty simple but something to build on.
The circuit and code were later modified to pass the temperature from a DHT11 sensor module, instead of the voltage reading, and the database now saves the fahrenheit temperature and the date and time of update. The data from the latest temperature update is shown when you visit the server site. The next step will be to add a switch on the site to request a new temperature reading and report that.
