caution:

This system is currently in the development phase, the code is not optimized, it is ugly and contains some really unpleasant things,

with love, by me.

Getting started

This project is divided into two sub-parts, a physical part, the arduino assembly, and a software part, the software for the arduino and the intermediary for the requests (here it will be the github repository).

Physical part

First, you need to configure the Arduino system. Connect the LCD screen to your arduino wifi according to this assembly.

What you will need :

• Arduino wifi
• 220 Ohm resistor
• Potentiometer 10K Ohm
• LCD 16*2

The scheme :

Example

When the system is connected, he display his ip.

some incredibe cable management 😂

Operation

operating mode n°1 :

The arduino is connected to the PI and display the infomation given by a script hosted on the Raspberry. The PI is tiny local web server, and request data from online APIs, sutch as meteo, coronavirus statistics, notification for new tweet, and more.

simplified operating diagram

operating mode n°2 :

The arduino is directly connected to the internet and sends quests then processes and displays data directly, which avoids using the PI.
