Working with schematics to wire digital outputs
Now, it is time to take advantage of the prototyping capabilities of the breadboard and start working on a more complex example. We will turn on and off 9 LEDs by using 9 digital outputs of the Intel Galileo Gen 2 board. Each digital output is going to control whether an LED is turned on or turned off.
After we finish the necessary wirings, we will write Python code that counts from 1 to 9 by controlling the digital output to turn on the necessary number of LEDs. In this case, our first approach won't be the best one. However, after we learn many things, we will create new versions and we will improve both the initial prototype and the Python code.
We need the following parts to work with this example: ...
