Science fair idea!

Former Member
Former Member over 12 years ago

Hi there! i am sophmore at Weslaco East High School (Weslaco Tx) and i am currently in the process of a Science Fair. Our school makes it mandatory for everyone in AP classes to participate in a Science Fair. (and it's worth 20% of the final grade soooo yeah i have to do it) My project last year was an Arduino controlled Drum machine (yes i am a drummer) . My partner and i used two solenoids driven by and arduino and a transistor circuit for the motion, and a MIDI drumset sketch written in Max 5 for the logic. Now, my partner graduated that same year and i have big plans for this project. My idea was i could use something more powerful yet very affordable (A RASPBERRY PI!! image) as a microcontroller with some sort of storage ( i was thinking an EEPROM) to save a pattern that could be input through a drumpad (some piezos maybe?)  I think this project could get me pretty far into the science fair, maybe even to the national level, but i felt it was better to consult with the community before i started.

 

Any help is appreciated!

    Why would you need an EEPROM? I would think it would be easier to store the pattern in a file on the SD card that the operating system runs on. PS: The Raspberry PI has a microprocessor, not a microcontroller…

    PS: The Raspberry PI has a microprocessor, not a microcontroller. Microcontrollers are chips that contain RAM, processor, and storage space(programmable memory). The main chip on the Raspberry PI only contains a processor and RAM.

    well i was thinking of using a drumpad with piezo discs to record a pattern that you can physically play. i thought an EEPROM would help store that data cause of its quick read/write abilities, but i guess an 8gb SD card would work alot better. Thanks!

    The SD card can be kind of slow, you could just keep your pattern in RAM as a linked list, and give the user the ability to save the pattern on the SD card if they wanted to reload it later.
