Midterm notes:

• Powerswitch tail controller four outlet
  • the little green thing on the side can do positive and ground
• Sensors
  • We have the sensors (up to 200 cm proximity) in our boxes
  • Additional sensors if you want to do something different
    • Ultrasonic ranger - sensor
    • IR ranger arduino - sensor
• You can just get it to turn on/off for the project and that can be it
• Probably a DC motor
• Activates when you walk pass it
• What do they expect to happen? Do the opposite
  • Turns back around
  • Scratch it from distance, when people walk in it does something, when they walk away it does something else
• Adafruit VL530x time of flight
• If you’re putting the arduino inside the box, you need to punch a hole, so that it could see through and sense
  • What are some other ways that the sensor could see through?
• Maybe the vinyl is the beatles and when it’s reversed it says “Paul is dead”, or something spooky when it changes directions
• Perforated board - for when you need a breadboard to last longer

Other notes from class discussions:

• Magnet switch, works with any magnet
• RFID reader
• Getting richness out of simplicity
• EL wire and sheets
• Capacitive switch for arduino
