Generates A Makefile for an Arduino when created with pure c

How to Use: Call script the name of the file where is to be compiled and uploaded. make: simply compile file make upload: will compile and upload to target machine

This script is adopted for the Arduino UNO Atmega328p

#!/usr/bin/env bash

    echo
    echo "Cannot generate makefile"
    echo "Please provide a program file name"
