	This looks a little messy, but it's mainly because of long cables. I've used wires with colors matching the breadboard diagram. You can see the green and yellow wires connecting to pins 2 and 3 - those are controlling the LED.		This looks a little messy, but it's mainly because of long cables. I've used wires with colors matching the breadboard diagram. You can see the green and yellow wires connecting to pins 2 and 3 - those are controlling the LED. The side-by-side red and yellow wires are controlling the LED and speaker, activating them simultaneously for morse code tones.

			And plenty of red and black wires scattered throughout to route voltage around!

			Here is the full diagram for our Arduino. We have a three-circuit layout:
			* LCD screen
			* Piezo speaker
			* LED bulb

			[[Image:bb_MorseCodeGenerator.jpg\|500px]]

			There's a lot going on here, so let's break this down into its constitutive parts.

			First, we have the LED circuit - this is our [[Blink Arduino Micro]]/Hello World circuit. Striaghtforward. This uses a single voltage pin, and the common ground.

			Next up, we have the [[Arduino LCD Display]] circuit, for printing things to the LCD display. This uses up two pins for signal wires (the SDA and SCL lines), and hooks up to the board's 5 V power:
