I wrote this script to compile and upload an Arduino sketch because I don't like nor use the Arduino IDE. I can use my editor of choice now and not need to fire up the Arduino IDE just to upload my new firmware.
I do this by, at the top of my sketches making two comments that describe the board and serial port to use, and calling Arduino from the command line to compile it and upload it for me. I might add this to my editor I use for convenience if I feel spunky, but for now I just made it executable and plopped it in /usr/bin.
The script arduload.py:
#! /usr/bin/python
# arduload.py
# By: Techb
# Date: Aug 26, 2015
# A script to compile and load arduino sketchs.
# This will check and make sure the tty is avail.
# In your sketch you need to have two comments at the
# the top of your file, example:
# // --board arduino:avr:uno
# // --port /dev/ttyUSB0
# --board, you will need the board your using.
# --port, is where your serail com is.
# Linux only, I don't plan to add Windows support
# since I don't use or have Windows. Feel free to add support.
# Tested on Arch Linux 4.1.5, Python 3.4.3
# Find more here: https://github.com/arduino/Arduino/blob/master/build/shared/manpage.adoc

Blink
Turns on an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the Uno and
Leonardo, it is attached to digital pin 13. If you're unsure what
pin the on-board LED is connected to on your Arduino model, check
the documentation at http://www.arduino.cc
This example code is in the public domain.
