11. Networking and Communications
Assignment for this week is to design, build and connect wired or wireless node(s)
with network or bus addresses and a local input and/or output devices.
The goal for me was to communicate from my iphone to my sensor that is
connected to my Esp board. I started with something simple to make sure
that I could get it working successfully. So I did my favorite...yes,
the powering on and off of LED's. I think that it is becoming the
"Hello World" of electronics circuit design...lol. Simple yet so
satisfying. I am using a program called Remote Xy.
This program allows you to communicate with sensors via wireless or
bluetooth connections on your microcontroller board. I created a

Led illuminated....this time via Bluetooth
Connecting iphone bluetooth to Esp32 & sensors
Here are the steps to allow your mobile device to operate
your sensors and projects in a simple easy to follow setup.
Code
Here is the code in Arduino IDE
