So the huge thing to remember when doing serial connections between hardware devices is that they need a ground connection in addition to tx/rx

An interrupt driven system

A specialized library for 2 arduinos

Methods:

• Use a prototype shield
• Shrink wrap the connections
• Build the entire circuit, including an Arduino on another board
• Use pieces of “header strip” to make connectors – or find connectors that plug into headers.
• Put duct tape over the whole thing
