YourDuinoStarter Blink

YourDuinoStarter_Blink

This is our version of the usual BLINK sketch everyone starts with. It has more structure and explanation and is similar to the many other example Sketches you will find here.

You can connect other output devices to Pin 13 and see them go On and Off like the built-in LED. Try these:

• BRIGHT 3 watt white LED module
• LED with a series 220 ohm resistor
• Buzzer module
• Red Laser Brick

You can copy and paste the text below into a blank Arduino IDE window.

/* YourDuinoStarter Example: BLINK
 - WHAT IT DOES: Blinks the built-in LED ON and OFF
 - SEE the comments after "//" on each line below
 - CONNECTIONS:
 - Built-In LED and resistor connected to pin 13
 -
 - V1.01 02/11/13
