Chapter 2 Blink LED

Small LED lamp experiment is the basis of comparison of the experimental one, this time we use

the motherboard comes with 13 feet of LED lights to complete the experiment, the experimental

equipment we need is the Arduino which each experiment must have and USB download cable.

Next we connect small lamp in accordance with the following experimental schematic physical

map.

Accordance with the good circuit after the link above figure, you can start writing programs, and

we let the small LED lights flashing. Lighting on for one second and off for one second. This

program is very simple. This is Arduino own routines Blink.

Example code:

ｉｎｔｌｅｄＰｉｎ＝１３；／／define pin 13

ｖｏｉｄｓｅｔｕｐ（）

｛

ｐｉｎＭｏｄｅ（ｌｅｄＰｉｎ，ＯＵＴＰＵＴ）；／／define interface is output

｝
