Abstract
This article shows the design and construction of some dancing fountains controlled by a pic16f877a. It also shows the code programmed inside this microcontroller, which was made using a PIC-C-Compiler for C language. The simulation and preliminary tests were performed in ISIS PROTEUS; the program converts the frequency signal to voltage. After the conversion, voltage ranges were assigned to activate each pump of the fountains' jets. The height that can be reached depends on how high the frequency is; then, the audio signal was coupled to an amplifier to improve the power of the audio signal to hear the music clearly, at par with the spectacle of the fountains working. In addition, the electronic designs of each board used are shown in detail. Finally, a vumeter was designed and installed to improve the visualization of the jets with illumination with LED lights changing to the rhythm of the music and the power of the output sound.
