 +To make sure components and connections between them work correctly it is necessary to conduct number of tests which help specify proper operation of the system.\\
 +Two key aspects need to be checked in the Arduino program: correct functioning of the appearing notifications about water level and value of the temperature in the fish tank, as well as correct functioning of light and pump switches. \\
 +What is more, the test that is needed to be performed is to check if the assembled system works correctly, above all: pipes’ connections, water filters and general flow of the water between two tanks.
 ==== - Project Planning ==== ==== - Project Planning ====
 Project Planning is developed according to Agile and Scrum methodologies (Figure {{ref>flabel1}}). With this method, the multitude of activities and steps in a project can be well divided and handled in different design sprints. The team will create a forced ranked project backlog. This is a list of tasks that need to be completed during the project. These are ranked by priority (pulling forward critical phases). The team will decide for a certain time period to finish these tasks. This is considered the sprint plan. Per sprint you have sprint backlogs, consisting of backlog tasks which must be included in the project during that particular sprint. Sprint backlogs are translated into sprint tasks. These sprint tasks describe how the items should be processed in the design. By working with sprints and specific backlogs it becomes clear what is included and what is not (avoiding scope creep). In order to keep track of each other's tasks and completed activities, we have chosen to work with Microsoft planner. This allows each group member to view and update his or her own tasks in an efficient manner. This can be seen in Figure {{ref>flabel2}}. The SCRUM team meets regularly in between. They have a team meeting every day in which each team member tells what he/she is doing and will be doing. During the retrospective meetings, the team discusses how the previous sprint went and how they can improve their teamwork.   Project Planning is developed according to Agile and Scrum methodologies (Figure {{ref>flabel1}}).

 The principle of the process is that bacteria convert fish waste into food for the algae. The algae feed on it and purify the water. Fish waste can be turned into plant food through the process of the "nitrogen cycle": the fish waste contains ammonia (which cannot be absorbed by the fish, as it is toxic) and the bacteria turn the ammonia into nitrate. The principle of the process is that bacteria convert fish waste into food for the algae.

 The marketing plan is a part of the market analysis. In the analysis, various information about the external and internal factors on the product are gathered. The awareness of this information influences and supports the decision-making regarding market strategies. It helps to define the main characteristics of the public needs and to help reduce the risk by gathering information about the potential that our product can have and to better understand where it will stand on the current market. The marketing plan is a part of the market analysis.

Starting in the bottom left corner, AIBSI Hydroponics Growing System is a really simple and small hydroponics system which is big enough for 1 decorative plant. In the same quadrant Edu Aquaponics Kit and Aquasprouts are found. Edu Aquaponics Kit is large enough to hold full size vegetables and is designed for educational purposes and is therefore placed more to the right of the diagram. Aquasprouts is a company which produces small scaled, however larger than Edu Aquaponics Kit, indoor and outdoor aquaponics systems which can be used for growing vegetables and for decorative purposes. The Aquaponic Source is a company which offers the same systems as Aquasprouts but also offers a semi-industrial scaled aquaponics system. It is therefore placed higher up the scale axis and because of the larger scale, it is believed that the functionality of this system is more diverse because more types of vegetables can be grown at the same time. Go Green Aquaponics offers custom made, full industrial scaled aquaponics systems which therefore result in even more functionalities. Compared to the aforementioned companies, GREEN·flow is placed at the same scale level as Edu Aquaponics Kit but due to its modular properties and the option to add different extensions, GREEN·flow is placed all the way to the right on the functionality axis. +Figure {{ref>flabel13}} shows the Brand Positioning Diagram in which the scale in which each brand operates is compared to the number of functionalities.

 Since the water level sensor works like a switch, it is only connected to an output and a ground pin. Accordingly, either the "HIGH" or "LOW" signal is sent to the microcontroller and the user can check if the water level is too low or high enough.\\ Since the water level sensor works like a switch, it is only connected to an output and a ground pin.

 Compared to the preliminary circuit diagram, the connection between the relay and the power supply for the pump and the LED has changed significantly. Since the pump received cannot be operated with 12V as initially planned, but now requires 230V, the light and pump can no longer be operated with the same voltage source. For this reason, it no longer makes sense to control the LED using the relay. However, as the LED RGB driver can also be controlled directly via signals using the microcontroller, this is not a major problem. The pump is still switched via the relay.\\ Compared to the preliminary circuit diagram, the connection between the relay and the power supply for the pump and the LED has changed significantly.

 However, a problem has developed as a result of the integration of high voltages due to the operation of the pump and the fact that the components are located close to each other. The switching and data transmission of the surrounding parts is influenced by the high voltage of 230V and thus no longer reacts according to the programmed commands. To counteract this problem, two 10kΩ resistors and a 47 μF 50 V electrolytic capacitor were used.\\ However, a problem has developed as a result of the integration of high voltages due to the operation of the pump and the fact that the components are located close to each other.

-As soon as the microcontroller receives the signal to switch on the pump, a while loop is started. As a result, the pump does not run all the time. This makes the system more efficient by saving electricity and balancing the water flow, which is affected by pipes of different thicknesses. It furthermore prevents the hopper from overflowing. To create a harmonious water flow, 3 seconds was chosen for the water flow time and 15 seconds pause (figure {{ref>pumpon}}). In the loop, it is also queried whether the user has made any further entries. If the user wants to switch off the pump, the while loop is interrupted with the command "break". +As soon as the microcontroller receives the signal to switch on the pump, a while loop is started.
