 +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.

 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.

The RGB LED allows the exact colour tone of the light to be set. A blue-violet colour tone with the RGB code 108, 17, 70 was selected here.

 It was important to check if the components work together properly to create a functioning and, what’s the key aspect, safe aquaponic system. Electrical components were separated to make sure that there’s no possibility of contact with water, what could cause danger. All the pipes were precisely connected to avoid any leak. Used filters prevent from getting through any unwanted materials.   It was important to check if the components work together properly to create a functioning and, what’s the key aspect, safe aquaponic system.

Similarly with the water temperature in the tank, the information about its value appears in the app. Thanks to that if any leak appears or system breaks, the user can react faster.   The user can check if the water level in the fish tank isn’t too high or too low.

 +User can sign into his/her account and check if everything works correctly. We take into account a possibility of switching off and on: a light and a pump.\\ 
 +What is more, he/she can check the water level and temperature in the fish tank. If it’s too high or too low, a notification appears on the screen. That helps the user react faster to any leaks or failures.\\ 
 +In future we consider adding automatic feeder’s controller, so with one button it will be possible to remotely feed the fish.\\
