Introduction: The Legoduino Circuit Learning Project
This project was created/designed/the brainchild of a 9-year-old girl. She has her own profile, NerdyCrochet, now that she is thirteen (2017) and legally able to publish her own instructables.
My daughter is the inventor of this Lego Circuit/Arduino Learning Project, I just helped with the pictures and the write-up of this instructable. She builds circuits here at home and has also been learning about Arduino and programming. She came to me one day with copies of real electronic components built out of Legos so she could practice making the circuits on her own. I thought it was so cool that it deserved to be shared with the instructable world.
Note: These Lego components don't actually transmit electricity or work like a live circuit. These are toys to create mock-ups of real circuit boards. My daughter uses the Lego components to double check her circuit diagrams so she doesn't accidentally blow up an LED on the real circuit board.
Following are a few of her creations. We hope you enjoy looking through the pictures and please let her know what you think. I'm sure there are other ways of building these electronic components out of Legos that are closer to the real-life examples, but hey, this is what my child came up with and I'm pretty darn proud of her. The fun of creating these models is digging through a pile of bricks and using your imagination--she challenges you to come up with some creative models of your own!
