This flute is an innovative and attractive product for kids to build it, achieving it by having amazing features like:Wireless connectivity by BluetoothWireless connectivity by Wi-FiMP3 files playerMIDI playerAbility of recording and playing your own soundsSocket for micro sd cardBuzzerReal time voice modulation and sound effects8 illuminated push-buttons, like a real flute has ( Do, re, mi, fa, sol, la, si, do’ )Open source Volume modulationOLED screen to make its use easierLike we have already said in the features description, this is a full electronic flute with wireless connectivity, being able to record and play sounds. The aim of this flute is to be a completely operating instrument to be used in a educational or even entertainment scenario, like the traditional one would. So, how? Here is where the VS1053b chip comes. We have learnt that it is able to reproduce several file extension types, including “.mp3” and “.ogg”(this last one is the extension it records the files with). The files we want to play will be saved in the micro SD card, and also the files it saves.Adding an OLED screen it will show us useful information from the flute’s status and the sounds we are playing. Here you can see all the components:PRO MICRO ArduinoESP8266 wifi moduleHC-05 bluetooth moduleLipo battery 3,7VPressure sensor MPXV7002DPAudio amplifier PAM8403Chip VS1053bTwo potentiometer (volume and effect)Micro SD socketOLED screenEight illuminated buttonsFlute’s PCBWe use Arduino core as main microcontroller.For the design of the PCB we have used the program of design “Eagle”. Also, we have used programs as “Fritzing” for the schematic wiring of some tests.-InspirationWe just needed to discover amazing devices like Makeymakey and Fenderino to know that we wanted to develop something even better with educational and artistic purposes.-PartsIt will use a Pro Micro as microcontroller, with an audio codec microchip (VS1053b) and an specific air flow pressure sensor.-Scenario (Uses and people who would use it)It is going to be a project destined to educational purposes, so the main idea is for it to be easy to build, and of course low cost and open source developed. -Main great featuresOne of the great things about this project is the wireless connectivity we have included. It will make it possible to control the device from a smart device via bluetooth and an easy app developed just for it. Thanks to the audio codec microchip we will be able to play different sounds, not just the fluty or drummy ones, turning them into a kind of synthesizers too. We add MIDI connetivity too.
