Build options

As you saw on the main page, there are three major configurations for the final shield. The one that's best for you depends on what you want to do.

Original configuration

If you had a v4 patch shield, it looked like this.

This configuration is best for general experimentation. It assumes you'll move the patch wires around, and change the patch completely from one experiment to the next.

It's good for connecting the Arduino to circuits on as many as four different breadboards at once.

Hardwire configuration

This one's a half-step between the original and minimal configurations. It assumes you'll want to hardwire a specific patch, but that you'll want additional access to the Arduino's I/O ports.

The version shown probably isn't very useful, but there are a ton of different options. You could replace the analog stacky header with pin header, hardwire all the analog input pins to jack 4, and leave the rest of the shield in original configuration, for instance.

There are too many variations to list (and way too many to photograph), but you're free to mix and match pins, stacky headers, patch headers, and hardwired connections in any arrangement you want.. and that's only if you want to limit yourself to the parts that came in the bag.

Minimal configuration

This one's best for permanent installations. It assumes you want a specific patch, have no need to make temporary connections, and want the extra strength of pin header.

You could plug this into an Arduino that controls all the lights in a room, for instance. You could also build a network of Arduinos, each running the lights in a single room, and all taking signals from a central control unit.
