Week 3 topics

  • Motors 
  • Solenoids
    • linear actuators that operate along the same principles as motors.
  • Relays
    • a relay uses an electromagnet to open or close a switch. They make really fun clicking noises and are often used to control high voltage/high current circuits from a smaller, safer one
  • Transistors
    • solid state switches used to amplify signals and power
  • Diodes
    • polarized components that make sure electricity only flows in one direction. useful in AC circuits, or in DC circuits when using an inductive load like a motor
