Components needed

We will need the following components for this chapter's project:

  • One Arduino Uno or compatible board
  • One HC-SR501 motion sensor
  • Jumper wires
  • For the challenge, you will need an LED
  • One breadboard
The breadboard is optional because you may connect the HC-SR501 motion sensor directly to the Arduino. You will need a breadboard to complete the challenge section of this chapter.
