Key ideas in Build Your First Smart Gadget

  • Electricity must return to its source to flow
  • LEDs are polarized and only allow flow in one direction
  • A gap anywhere in the path stops the entire flow
  • The long leg (anode) must connect toward the positive power source
  • The negative terminal is the 'return' for the loop
  • Flipping the component fixes a 'backwards' break in the loop
  • The necessity of a closed path for electricity to flow
  • Identifying polarity in components like LEDs
  • Unrestricted electricity can generate enough heat to melt or 'pop' small components
  • Resistors limit the amount of current flowing through the loop
  • Holes in the same row are physically connected by metal underneath
  • The center notch prevents the left side from touching the right side
  • The protective role of resistance in a circuit
  • A switch acts as a movable bridge in the loop
  • Pressing the button closes the physical gap between two wires
  • Understanding the internal connections of a breadboard

The Path of the Electron

Picture this: you have a tiny LED light. Unlike a simple wire, this component has a specific 'front' and 'back' for electricity. What is this property called?
