Hey everyone!
I have completed my first real project using the Arduino products. I am open to any constructive feedback. Remind that the main goal of this project is to learn by doing. Hence, certain architecture decisions may not be the most optimal 
You can find the repo here.
What does it do?
Just looking at it from 30,000 ft, why can't the functions of the UNO R4 and ESP32-S3 all be rolled into the UNO Q?
Hey!
So it is a set of 3 boards communicating to a web dashboard via a MQTT broker for Home Monitoring. 2 boards serve as BLE peripherals with sensors/actuators and 1 board serves as the central BLE device and gateway to the MQTT broker.
Indeed, ESP32-S3/UNO R4 are not required for the temperature sensor/RGB LED/Servo Motor and Person Detection as UNO Q is able to do all the work as it also has a WiFi chip.
The reason for such an architecture was simply for me to learn (as I am fairly new to the maker world ) how to connect multiple devices together and develop a more complex architecture.
Hope this helps
As a self teaching tool it has some merit, but as I said it can all be done with 1 board.
This is great
