Buzzer

I made an alarm that repeats a blaring sound until you disconnect the wires or battery. This should help people that have trouble with turning off their alarm in the morning and going back to sleep. It is built from and Arduino Uno, breadboard, buzzer, wires, and 9v battery.

1. Arduino Uno
2. Breadboard (includes wires)
3. Compatible buzzer
4. 4-6 Breadboard wires
5. Computer cable for Arduino
6. 9v battery and adapter (optional)

Copy this model in Tinkercad Circuits, including the code. You can add a "forever" block for it too repeat forever, or a wait block to set a timer. TinkerCad

Build the circuit with your Arduino and Breadboard, exactly how it is in Tinkercad.

Go to the code blocks in Tinkercad and click "Blocks and Text" and copy the text code that pops up. Paste the code into your Arduino software, plug the Arduino into your computer, and upload the code.

The device will function when plugged into your computer, but a 9v battery and adapter is much more portable. Set up the alarm by connecting power after the code has been uploaded, which will start a countdown for you selected time.
