Introduction: Makey Makey Game Controller, Piano, Sound Effect All-in-One!
Create a LEGO Piano, Game Controller, and Sound Effects Machine with simple levers and bring it to life with a Makey Makey.
Step 1: Intro to Project
Here are some of the things you can do with a few levers made with LEGOs and your Makey Makey
Step 2: Build the Base
- Pick a large LEGO square to build your base on.
- Collect six 1x2 brick, one 2x8 brick, two 2x2 brick, and one 1x8 flat lego.
- Assemble as seen in video.
Step 3: Make a Piano Key
- Collect the long 1x12 brick with holes, two sloped legos (see video), and one 1x2 thin LEGOs.
- View video for details on LEGOs and assembly.
Step 4: Make the Level
- Collect two 1x2 bricks with holes, two 1x2 bricks, one rod long enough to span the bricks, and 2 end legos (see video).
- Assemble as seen in video.
Step 5: Add Your Key
- Create the number of keys desired. I made 3 more.
- Assemble them onto the lever rod as seen in video.
Step 6: Add Weights to Lever
- Add weight to each key as seen in video.
- Test each key.
- Weight can be added as needed. If keys stick widen the brackets on the end.
Step 7: Add Aluminium Tape to Keys
- Detach keys and flip them over
- Cut small pieces of aluminium tape, one for each key
- Apply tape to the end edge of each key.
Step 8: Add Aluminium Tape to the Base
- Cut one narrow strip for each key
- Cut one piece for Earth that will hit each key. Example above is in the shape of a "U". Each end of the "U" spans across 2 keys.
Step 9: Assemble Tape
Assemble tape on base as seen in video.
Step 10: Arrange Alligator Clips
- Gather one alligator clip for each key and one for Earth
- Remove 2x8 brick
- Secure alligator clips under brick
Step 11: Clip All Alligator Clips
Clip all alligator clips to the aluminum tape
Step 12: Reassemble and Test It.
- Reassemble piano
- Open Piano app - apps.makeymakey.com/piano/
- Watch fully assembled piano
Step 13: Special Effect Piano - Various Sound
Here is a variation on the piano for sounds effects:
- Download Sound Plant - soundplant.org/download.htm
- Add sound effect for each arrow key
- Design weights with the character of your sounds. In this one there is a bubble, fire crackle, boom, and hazard sound.
Step 14: Sound Effect Piano - Halloween Sounds
Here is a variation on the piano for sounds effects:
- Download Sound Plant - soundplant.org/download.htm
- Add sound effect for each arrow key
- Design weights with the character of your sounds
Step 15:
Here is a variation on the piano for a game controller:
- Add special LEGOs to signify each direction. I used flags for left and right, then torches in normal and upside down position for up and down
- I used one of my favorite directional game Apple Worm - https://bigdino.com/play/1708/Apple-Worm
Step 16: Literature Variant
- Form groups
- Each group make a different key with recorded sound for story prompt
- Make a lego weight that give an idea of what the prompt might be about
- Download Sound Plant - soundplant.org/download.htm
- Set a key for each recorded story prompt
- When the key is pressed it will play the prompt and the kids take it from there
Add a little programming in scratch
- have each key represent a different type of word - nouns, verb, adjective, adverb
- record words for each
- when key is pressed randomly play from the bank of word types
