;; Authors: stardiviner <numbchild@gmail.com>
;; Package-Requires: ((emacs "24.4") (org "24.1"))
;; Package-Version: 1.0
;; Keywords: arduino org babel

;;
;;; Commentary:
;;
;; Like the following src block, press =[C-c C-c]= to upload to Arduino board.
;;
;; #+begin_src arduino
;; // the setup function runs once when you press reset or power the board
;; void setup() {
;; // initialize digital pin LED_BUILTIN as an output.
;; pinMode(LED_BUILTIN, OUTPUT);
;; }
;;
;; // the loop function runs over and over again forever
;; void loop() {
;; digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
;; delay(100); // wait for 0.1 second
;; digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
;; delay(100); // wait for 0.1 second
;; }
;; #+end_src
