Week 01
This week I learn some basic things about Adunio, like how to set up breadboard, how to soldering and learn a lot of components.
The first problem I meet is this, I didn't know why this is a short circuit. Then I realize that the breadboard's short strips are connected. And the electric current will pass through the path of least resistance. Both of the LED’s connections are in the same junction row， and the electric current pass through the under road.

Tips
Here are some Tips for myself
-
Use different colored wires to connect INPUT (red) , OUTPUT /GND (black), SIGNAL (blue).
-
When the LED is not lit, use an ammeter to detect if the route is poorly connected
-
Understand the basic parameters of the parts. For example, a 19V power supply cannot power the model 7805.
