11. The arduino way
“the Arduino philosophy is based on making designs rather
than talking about them. It is a constant search for faster
and more powerful ways to build better prototypes. We
have explored many prototyping techniques and developed
ways of thinking with our hands.: • Prototyping

13. • Current is a circle – starts at an i/o port, flows to GRND
• Use red for positive wires (from output)
• Use black for negative wires (to GRND)
• Look it up, before you hook it up

20. Hello world! (=blink)
File examples basics BLINK
/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
This example code is in the public domain.
*/
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000);
// wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000);
// wait for a second
}
