Week 3: Class Notes

  • Environment sensors (1): Sensing wind and rain
    • How weather station works – mechanism, electronics and programming
      • Rain gauge (tipping buckets), wind speed, anemometer
      • RJ-11 Connector
      • Demo: Controlling solenoids with weather station to sonify weather data
    • Wind sensor from Modern Device
      • Hot wire technique
  • Using wire wrapping tool (found in the shop)
  • ADPS9960: proximity, light, color (rgb), and gesture sensor
    • Reference: Arduino’s ADPS9960 library
    • Enclosure for improving color sensing accuracy
    • Sensing hand gestures is just one way of using the gesture sensor. Think creatively, the sensor can be used for sensing movements of any objects in various contexts/designs. For example…
      • Demo: ping pong ball dimmer, which uses a gesture sensor to sense movement of a ping pong ball moving along a track to slowly fade in/out light
