Objective
A lot of questions
Pick one question and make a statement out if it:
Do we have time and energy to do what we love?
Hypothesis
From Hypothesis to Data
Tools selection
Arduino

First Experiments
We started gather data to understand the difference between natural and artificial light. We used a a resistor of 1K.
March the 9th, rainy and cloudy day in Poblenou, Barcelona - We still could spot significant differences from outdoor and indoor:
Data Capturing Strategy
We used two different strategies to capture data:
Materials Needed
Adafruit Feather ESP32
LDR Sensor
Laptop
ArduSpreadsheet
IFTTT
Orange3
Twitter account
Detail Setup Instructions
ORANGE3
First Trial: World Happiness Report
First trial we tried to upload data from the World Happiness Report 2022, the range was too wide, too many information and detaled classification. It is based on too many socio-economic aspects, that's why we decided not to base our research on it.
Second Trial: OECD.Stat
Then we decided to narrow down the research field and get the data drom OECD.Stat, a survey that gathers data about the percentage of adults who reported that over the last 12 months it has been difficult for them to fulfill their family responsibilities because of the amount of time they spent at work.
Third trial: Twitter
Collecting data from Twitter throughout Orange3 - SENTIMENT ANALYSIS
Query word list: over time; over working
Language: english
Tweets: 1000
We created a word cloud out of it
And then analyized the emotions throughout a Box Plot
LDR Sensor Data
To collect and log the LDR sensor data we employed a couple of strategies. First, we downloaded Arduspreadsheets and were able to log the LDR data in a .csv file. We took readings of the resistor value every 10 seconds and each reading was stored in a spreadsheet with a corresponding timestamp.
After this we realized we wanted the device to be mobile so it could be carried with a person to monitor the light levels they encounter throughout the day. For this we first tried to connect via bluetooth to a cell phone to collect the data. We made the bluetooth connection and could see the data but couldn't find a good way to save the data. After this we went with the option of sending the data over WiFi to an online spreadsheet. To make this happen we used If This Then That (IFTTT) to connect to Webhooks to publish the data over Wifi. After this we were able to connect the ESP32 to a phone hotspot and the device was mobile! We tested out different light levels throughout the IAAC building and outsice in the sun.
Tips
Tutorial for publishing sensor readings to Google using IFTTT
Arduino Serial to Spreadsheet
Pick the right sensor/tool for the application. In the end we didn't find the light sensor readings as useful for supporting our research for the time we had.
It will take WAY more time than you imagine to get everything working. Make extra allowances for time.

Data Insights
A hypothesis may be testable, but even that isn’t enough for it to be a scientific hypothesis. In addition, it must be possible to show that the hypothesis is false if it really is false. Proving it's true it will require testing all possible combinations, that's hard, maybe impossible.
