+;;; 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
