The second one is to detect light levels and turn on the front light in response to that. 
 +The software works in a loop, checking the light level and then switching the level output on pins connecected to the front light. Next it should check whether a Bluetooth conncection has been established. If so, is should read all sensors and send the results to the application.

 Due to the circumstances we could not test the connection between Arduino and the application. In order to test the main functionalities, we generated fake data while traveling around the streets. This data was then used to fill both the internal and external storage. Next it was downloaded back from the database and used to simulate routing in the map component. We also tested the user authentication by creating some accounts and emulating casual use of the application while logged in. \\ Due to the circumstances we could not test the connection between Arduino and the application.

In all screens, in the top left corner the user can login or logout. The "?" button triggers a popup explaining the need for authentication.

 +In **Figure {{ref>firebase}}** we can see the desktop view of the IoT database storing the measurements performed by all users. IoT platforms usually do not use SQL syntax of tables and keys, so in our project's case we used Cloud Firestore that implements hierarhical stucture of collections and documents. To the left we can see different collections of data, one for each measured value and the locations. Each collection contains documents(in the middle) that  each correspond to a single measurement and contain a collection of values associated with it. In the figure we can see to the right a single record of carbondioxide measurement containing the measured value, user key - IdBiker(assigned during authentication), measurement key  and a timestamp. Upon download of the data by the application, it associates the measurements with their location using the IdBiker and timestamp fields that are present for each record.

 This chapter summarized the entire process of creating the prototype visuals, starting from concept and sketches, through technical drawings and finally 3D renders of the product. It shows the steps taken in developing the electronic circuit, which included schematics of the circuits, choosing appropriate components from ones available on the market and calculating the power usage. As the manufacturing process was described, we considered both the method, being 3D printing of the prototype and injection molding for mass production, as well as the materials which should be used. The functionalities of both the application and the device itself were discussed and finally, we recounted the process of testing the circuit elements, Arduino software and the application. \\ \\ This chapter summarized the entire process of creating the prototype visuals, starting from concept and sketches, through technical drawings and finally 3D renders of the product.

 The concept visuals are well defined and thought through. Materials were chosen with great care to make sure they are both ethical and sustainable while still fulfilling the needs and requirements of the project. The circuits were designed to both be safe for the user and to provide a sustainable energy source. The application was designed having in mind the comfort of use for the device owner, allowing them to apply the gathered data in their daily lives with the use of navigation. While regretfully, we could not test it with real data, most of the planned functionalities were realized. \\ The concept visuals are well defined and thought through.

 +By collecting data and sharing them with a common cloud, the whole community can have free access to the pollution map. In that sense, people can  
 +link together, share their feelings about the air conditions, try new routes provided by the map together and connect to bike users. Furthermore,  
 +the device has another important role that is to make people use their bikes. As GOairLigth is made to improve the road conditions for bikes,  
 +people are more willing to take their bicycles to commute throughout the city. The feeling of safety can, even more, be improved by the creation  
 +of real bike lanes.

-we did simulate how the app and the device should have been working.+of expertise, allowing me a broader look at my field of studies. I have also learned many skills connected to my field, such as knowledge on  
 +embedded systems and mobile android applications. I believe these skills will further aid me in the future both as a student and as a  
 +professional.  The online learning we were forced to adopt was a challenge, especially coordinating work with distant teammates. However,  
 +I believe it was a valuable lesson on how to work with remote teams, which is not uncommon in the IT job market".\\ 
 +**Logan**: "During the EPS, I have learned how to work in a multinational team effectively and efficiently. The EPS has definitely improved my  
 +communication skills, in terms of conveying different ideas and messages across the board to the whole team. Unfortunately, the COVID-19  
 +pandemic played a big part in our EPS semester. However, skills were still developed through the use of online teaching and video software.  
 +In the time spent completing the EPS, a part that I will look back fondly on, was the opportunity of meeting new people from all over the world  
 +and to contribute my skills in a multi-skilled group."\\ 
 +**Mélissa**: "EPS@ISEP was quite a challenge for me as the creation process from the design to the development of a proof-of-concept prototype  
 +is out of my study field. However, EPS is more than the creation of a product, it is about international teamwork. Specifically, it helped me to  
 +develop team management, searching and scientific writing skills. Thanks to this project, I now know more about the marketing field, and its  
 +important role in a company, and how to communicate efficiently through visual communication supports as well as with my team. COVID-19  
 +situation hardened the realisation of the project and made it even more challenging, but we successfully managed it!\\ 
 +**Kaan**: "I have learned a lot by working together with students from different fields and seeing their strengths and weaknesses. It ranged  
 +from self-learning (working with new tools and improving my design skills) to peer-learning (understanding how other fields are equally relevant  
 +to the design of functional devices). Due to the outbreak of the pandemic, we were forced to switch to distance teamwork, resorting to online  
 +tools for communication. Although it was a challenge, the team was able to continue working and communicating remotely. Overall, this gave me  
 +experience and knowledge on how to work as a team without being physically together."\\ 
 +**Juho**: "My experience with the EPS programme has been positive. I have learned how a team should work as a whole and how to improve my own  
 +doing within the group. EPS was not just focused on doing a project, but on learning other skills as well. I have learned other subjects like  
 +Portuguese, basics of coding, project management, marketing, energy and sustainability. The team was composed of students from all over  
 +the world and everyone had a different educational background. Before I used to do my work just before the deadline and now, after this teamwork  
 +experience, I realised that team partners have to work side by side to go further."
