-As shown in Figure {{ref>elSch}}, there is an Arduino Nano used to operate all components. The 14 digital I/O and one Analog Input of the Arduino are used to drive the servo motors,  to power the LED and readout the button.  +As shown in figure 12, there is an Arduino Nano used to operate all components. The 14 digital I/O and one Analog Input of the Arduino are used to drive the servo motor, to power the LED and readout the reed switch. The servo motor and Arduino are directly powered by the battery. To control the servo the digital output D2 is used. The three single colour LED and the two RGB LED are connected to the digital Outputs D5-D12. To limit the current in the LED to a safe value, every LED is serial connected to a 330 Ω resistor. In addition, the reed switch is connected to D12 which is set on pullup. In case of a closed reed switch the digital pin is directly connected with the GND. 
-To power the three servo motors, a voltage regulator 7805 is used. This regulator has a current capability of 1.5 A. Since every servo has a maximum working current of 500 mA [(Micro9:online)]  +
-, the voltage transformer is able to power all of the servos. The digital Outputs D2-D4 of the Arduino Nano are used to control the servos.  +
-The three single colour LED and the two RGB LED are connected to the digital Outputs D5-D12. To limit the current in the LED to a safe value, every LED is serial connected to a 330 Ω resistor. In addition, the button is also serial connect to an 330 Ω resistor to protect the analog Input A1. In case of a pressed button 5 V are directly connected to the analog Input. The resistor has to function to protect the Arduino board of this voltage.+

 The combination of blocks, the transfer to the Arduino software, the compilation and the upload to the Arduino board works without any problems. After uploading the program, the electronic components are reacting accordingly the arranged blocks. The performance of the code can be interrupted by triggering the reed switch with a magnet and continues after removing. Before starting the performance of the code a countdown sequence takes place.  The combination of blocks, the transfer to the Arduino software, the compilation and the upload to the Arduino board works without any problems.

 +The project development stage involved beginning of the process of development of an educational toy, designed for children. Here the main aim was to create the toy, bubbles as a didactic robotic fish that would be able to operate efficiently in an aquatic environment. Bubbles was required to be easily controlled as users would range between the ages of five to ten years old, therefore anything more complicated could not be used. Not only with this product allow children to have fun but it is also an excellent introduction into the world of electronics and programming, benefiting the young users in later life. The prototype was developed by analysing existing products on the market and each team member providing their own thoughts and ideas. This process enabled the team to establish the best type of robot to use and the most successful techniques to use. The prototype will contain a balanced body shape with an articulated tail, powered by a servo to support the body and allow easy control of the movements. Waterproofing was essential for the product and although some setbacks were encountered, these were overcome through teamwork and dedication to ensuring bubbles would be a success.
