What if I can't get either of my sensors to work? Use the VCNL4040 that you already used in the exercise 3.3.
Exercise 7.1:
Build a stopwatch with the smart servo and two buttons.
The movement of servo indicates the seconds elapsed.
Clicking the first button starts and stops the stopwatch. The 2nd button resets the stopwatch.
TIP: Use the millis() function to find the elapsed time.
Exercise 7.2:
Develop an interactive device, taking inputs from one sensor and providing a physical output such as lights or movement.
| Sound (Buzzer or Loudspeaker) | Movement (Motor, Solenoid, Servo) | Light (LED, neopixel, lightbulb, laser) | Tactile (vibration motor, actuator, Peltier element) | Graphic Display (OLED, LCD, 7 segments, Printer, laptop screen with Processing) | |
| Sound (microphone, piezo) | |||||
| Movement (distance, motion, gesture, gyro, pressure, flex sensor) | |||||
| Atmospheric (Temperature, humidity, air quality, pressure) | |||||
Bio-sensor (Pulse, GSR, EMG) | |||||
| Light (colour, luminance, IR) | |||||
| Touch (buttons, pressure, capacitance) |
