Clap twice to turn on and off a bright LED.
No more spreading germs through doorbells.
I accidentally put that there. Removed it now, thank you!
You can use a speaker. In fact, you can probably make this sound more like a doorbell. I have never used one myself but I have heard that they are not too hard to use.
Vcc goes to 5V on arduino
Gnd goes to ground pin on arduino.
Trigger goes to pin 8 on the arduino.
Echo goes to pin 9 on the arduino.
Positive leg goes to pin 11 on the arduino.
Negative leg goes to GND on arduino.
I just edited the comments on the code for it to be easier to understand. Thank you.
