A piano built with a basket of fruit, a microcontroller and a computer.
The idea is from Makey Makey, but uses different hardware and software. An mbed enabled microcontroller with USB is used.
Hardware
- An Arch board
- A basket of fruit
- A computer with AC power
- some wires
Software
- Click this link to import the program to mbed online compiler.
- Compile the code and download the binary file - Fruit_Piano_LPC11U24.bin.
- Connect the Arch board to the computer and long press the button, a USB drive named CRP DISABLD will pop up.
- Delete firmware.bin and copy Arch_GPIO_Ex1_LPC11U24.bin to the USB drive.
- Quick press the button to run the program
- Wire some apples or bananas to A0 - A5 (P0_11 - P0_14, P0_16, P0_22) pins of the Arch board
- Open Fruit Piano and play
Have fun!
