Arduino Water Detection Alarm Project

This tutorial guides you through creating a simple water detection circuit using an Arduino microcontroller. The project aims to prototype a water detection alarm for monitoring water levels in a sump pump crock. The tutorial covers the materials needed, the setup of the water detection circuit, and the integration of a speaker circuit. It also explains the code used to operate the circuits, demonstrating how to combine them for a functional prototype. The project is a proof of concept, focusing on quick prototyping and basic functionality.

What is the primary purpose of the water detection circuit project?

• A push button circuit

• A humidity sensor

• A light sensor

What is the role of the 10K ohm resistor in the water detection circuit?

• To hold the pin low

• To connect to the LED

• To increase the voltage

• To amplify the sound

What function is used to generate sound in the speaker circuit?

• Sound()

• Beep()

• Tone()

• Buzz()

What is the frequency used in the tone function for the speaker circuit?

• 1000 Hz

• 1500 Hz

• 2500 Hz

• 2000 Hz

What is the purpose of the delay in the speaker circuit code?
