MY PROJECT

Watt a House!

How I made a tiny house turn its lights on and off, with help from Gru and the Minions!

By Sebastian Ballance · Third Year, Lower Elementary

What I built

A house where I can turn on the lights!

  • living room & kitchen
  • bedrooms upstairs
  • porch & outside lights
  • a fireplace that flickers

The tricky part

How do you control SO many little lights at once?

I needed a boss to give orders… and helpers to do the heavy work.

Meet the boss: GRU

  • Gru is the brain (a tiny computer)
  • He gives the orders
  • But he's too weak to do the heavy work himself!

Meet the workers: the Minions

ground floor
upstairs
outside
fireplace

Each minion turns on one part of the house.

How it works

  1. Gru shouts: “Turn on the outside lights!”
  2. That minion flips its switch
  3. The lights glow!

Let's try it!

Open the Minions page and click a button!

Try “Exterior lights” and “Fireplace”

(Grown-up: open gru-wiring.html for the live demo)

What's inside

  • Brain, the boss (Gru)
  • Chip, the minions (helpers)
  • LEDs, the little lights
  • Resistors, keep the lights safe
  • Battery, the power
  • Wires, connect it all

4 cool things I learned

  • Electricity flows in a loop, like a race track
  • An LED is a tiny light that only works one way, backwards it stays dark!
  • A transistor is a tiny switch, a chip has billions, each smaller than a hair!
  • A resistor is a seatbelt for the light so it won't burn out
THE END

Thanks for watching!
