REPORT SECOND PARTIAL

We used various types of softwares to simulate the behavior of circuits for the power supply, communication with the audio device, the logical combination system, the power circuit and the circuit for water pumps; in addition to this was investigated about the operation of various fountian dancers, according to the information gathered was discovered that the largest number of similar projects are carried out in larger size and with circuits that operate on alternating current, however due to the specifications of the project it was decided to use direct current components which will provide us with a better functioning and thus determine the operating system of our prototype. The major constraints were the cost of materials and develop the electronic circuit more optimal for the operation of the source.
