Time Table

Day 1

Today, 24 May 2019, my group focused on testing components and searching for eventual broken components and, after founding and replacing a few of them, we started to program the Arduino.

Later we have been able to make it work, also we added a red led, reporting that there is smoke in the air, and a green led reporting that the air is clean enough.

Day 2

Today, 25 May 2019, I and my group made a program to let the Gas Sensor work with a 16x2 Display, but we found some problems building the circuit.

Day 3

Today, 27 May 2019, I and my group used the Gas Sensor and the 16x2 LCD Display together to show on the display the value of the gas detected by the sensor, when the value was higher than the limit the display showed "Pericolo".

We Naturally kept the two led part of day one.

Day 4

Today, 28 May 2019, I and my group succeded in adding a Buzzer, that produces a sound whenever the gas is detected. Also, we opened a website in witch we uploaded the diary and, during the Bugatti's teacher hours we started taking data from Arduino and putting it in our laptop file by using a program.

Day 5

Today, May 29^th 2019, my group and I started making the English version of the diary. Also, during the I.T. hour, we focused on trying to put the Arduino's data on the website.

Day 6

Today, May 30^th 2019, my group and I tried to develop an app that will be able to see the data on the website.

Day 7

Today, May 31^th 2019, all the class visited "INXPECT" company that produces security devices that, by using radar sensors, are able to detect the presence of humans and distinguish them from animals. This sensors are used mainly in companies to detect potential intruders, but if put near machine tools, in case a human gets too close to them, they can automatically stop them.

Day 8

Today, May 1^st 2019, during T.P.I. hours we learned to use MIT App Inventor 2.

Day 9

Today, May 3^rd 2019, my group and I started writing the program that will be used to read the data from Arduino and send them to a Cloud Server, we spaghetti coded from our I.T. Teacher Github (https://github.com/alessandro-bugatti/dweet_client & https://github.com/alessandro-bugatti/libreria-seriale).

Day 10

Today, May 4^th 2019, my group and I split up in two parts:

the first one started making a slide presentation that contain all the things we have done during the project school-work, and the second one kept working on the app.

Day 11

Today, May 5^th 2019, my group and I added a humidity and temperature sensor to our project, we also finished the app with MIT AppInventor 2.

Day 12

Today, June 6^th 2019, my group and I have done a report about the project school-work:

• We have done a circuit able to let the gas sensor, the humidity and temperature sensor, a 16x2 display, a potentiometer and a buzzer work in harmony.
• We created a website in which we uploaded the Italian and english diary, the evolution stages of the project, the components of the Arduino's kit and some photos of our work.

We also were able to let the Arduino send the data to the website, but we weren't able to program the app with MIT App Inventor 2.
