This project is an attempt to develop a fully automated system that plays the Berimbau through the MIDI protocol. The hardware we are using is the Arduino UNO platform with a custom built shield.
Details
In the video we explain a little more about the project.
$ sudo apt install make avr-libc avrdude binutils-avr gcc-avr
Arch Linux
$ sudo pacman -S avr-gcc avr-binutils make avr-libc avrdude
Remember to give the current user permissions to access serial ports (on Ubuntu and derivatives you need to include the user in the dialout group, on Arch Linux the group is called uucp). Don't forget to logout and login to update the user permissions.
MacOS
The required dependencies can be installed through the homebrew package manager.
Open a terminal and navigate to the cloned repository directory. Then execute the make command to compile the source code. To upload you need to issue the "make burn PGPORT=xxx" where 'xxx' is the serial port name where the Arduino UNO is connected (on Linux it's typically /dev/ttyACMx or /dev/ttyUSBx, on macOS it will have different names depending on the USB to Serial bridge used, but is typically /dev/tty.usbmodemxxxx, on Windows it will be a COMx, where 'x' varies from 1 to 9).
