1. Super Mario Mushroom Game
2. Super Mario Mushroom House Cheats

Submitted for the approval of the Instructables society, I bring to you another electronic LEGO project with a retro video game theme!

For New Super Mario Bros. Wii on the Wii, Red Mushroom House Chart by alphasoldier. The Weird Mushroom is a power-up in Super Mario Maker and Super Mario Maker for Nintendo 3DS. Upon use, Mario turns taller and slimmer and gains the abilities of Luigi, with higher jumps but lower traction. According to Takashi Tezuka, the form came from a bug that happened in development that made Super Mario skinny. However, Tezuka and the team liked Weird Mario's design, so they implemented.

Using the exact same principles for design and engineering as my Electronic Super Mario Starmen, I've built another series of small musical LED sprite pieces. These ones are roughly the same exact size of their predecessors, contain the exact same electronics (the circuit, the batteries, LEDs, speakers, and Arduino code), and are assembled in the same fashion -- only instead of invincibility stars, I've got four different mushrooms with multiple audio options!

The tutorial for these mushrooms will be identical for all four, but here are the color choices:

1. Green head with white dots: 1-up from the 16-bit era
2. White head with green dots: 1-up from Super Mario Bros. 3 (same thing as above, only with its base colors swapped)
3. Red head with white dots: power mushroom from 16-bit era
4. White head with red dots: power mushroom from Super Mario Bros. 3 (same thing as above, only with its base colors swapped)

For both of the green mushrooms, I've used an Arduino melody version of the 1-up (extra life) sound effect traditionally used in the Super Mario franchise. I have two different Arduino codes used for the red variants: the 16-bit red mushroom contains a small segment of the Overworld Theme from Super Mario World for SNES, while the other red one uses the End-World Victory Music (after beating an Airship) from Super Mario Bros. 3. for NES. You're absolutely free to deviate from my musical codes and swap out any music you'd like, so long as you know how to tweak the Arduino code and manipulate notes. I personally recommend using the Super Mario World and Super Mario 3 songs for their corresponding mushrooms to maintain video game accuracy.

Super Mario Mushroom House Cheats

• Like all of my Instructables, this is not an easy nor cheap project to build. Although the LEGO and electronic portions are both significantly easier than the LEGO DL-44 Blaster I built in the summer of 2014, this isn't a project to be done by amateurs with little skill. Each Mushroom model contains roughly 300 LEGO pieces: some have slightly more or less depending on the particular color model. For instance, the green mushrooms have multiple shades of green and thus require more tiles. On average, I can't really give an estimation for the price, since I bought most of my electronics parts in large batches at once. Many of the pieces can be bought for less than $1 US from various online sources, and you'll probably spend about $10-15 worth of LEGO pieces, give or take.
• The electronics skill required is novice-to-intermediate, but nonetheless requires the ability to solder and identify components (e.g. adhering to proper LED polarity, using proper resistors, using sufficient battery power).
• Programming the sound chip requires a working Arduino board. I use an Uno, but from what I've gathered, the Mega and other models can be substituted.
