$\textnormal{HW - Blinking LED}$

video-hw-blinking-LED-testing.mp4

• A blinking LED project using Uno R3, AVR LibC and C language.

$\textnormal{System Design}$

$\textnormal{Local Development}$

• This works well in Linux based system.

• Install the necessary tools inorder to interact with Arduino without the IDE.

# Standard library for Atmel AVR devices.
# This contains most of the features required by the ISO C standard.
sudo apt install avr-libc

# A program for downloading and uploading on-chip memories of Atmel AVR Microcontroller.
sudo apt install avrdude

# A program to assemble and manipulate binary and object files for the AVR architecture.
sudo apt install binutils-avr

# GCC C cross compiler for AVR.
sudo apt install gcc-avr

• Take note that the library headers might be placed here /usr/lib/avr/include.

• Run the command below to execute the commands specified in Makefile.

# Change directory to the root of the project.
# Execute the MakeFile and upload in the Arduino microcontroller.
make
