Q

What does a diode do and what are the different types?

A
  • Only allows current to flow through in one direction
  • Light-emitting diode (LED) = emits light when current flows through it

Q

What is an LDR and thermistor?

A
  • LDR (Light Dependent Resistor) = resistance decreases as light intensity increases
  • Thermistor = resistance decreases as temperature increases
