to mark a step as I won't lie to you, I was highly influenced by the 'Portal Gun' of Rick Sanchez in the great TV show 'Rick and Morty'.
Sadly, this device won't allow me or anyone else to travel through dimensions.
Nevertheless, it will gives you a lot of data concerning your environment and the air that you are breathing.
Equipped with 4 gas sensors, 2 hall effect sensors, a digital thermometer and a LCD, the Arduino Uno was loaded in no time.
I'm glad I could use nearly all the pin of the microcontroller which, in most of the project I've seen, requires so few.
I really wanted the project to be able to be easily handle by hand.
This limited me in the choice of a casing.
I finally went for a 7¨x 5¨x 2.5¨ acrylic plastic casing.
This is the real minimal dimension possible to work with to build such a project. Trust me.
See the video of the main function of the project here:
You will see in this video how everything fits nicely in there:
There is probably 10 versions of the code for this device.
The final one is the right one and the more accurate to what I wanted it to be.
If you are interested, just let me know and I'll try to share all the code with you.
