Float Switch

• What is the main objective of designing a float switch?

  To design and implement a basic float switch
• How do float switches function?

  They detect fluid levels using buoyancy
• What relationship does pressure have with float switch operation?

  Pressure affects the float's buoyancy and function
• What should be evaluated for improvements in float switches?

  Improvements in float switches and circuitry
• What is required for the float switch experiment write-up?

  To present findings and analysis of the experiment
• What does buoyancy refer to?

  The upward force exerted by a fluid
• What does it mean to float?

  To rest on the surface of a liquid
• What principle explains the buoyant force?

  Archimedes' Principle
• What happens when the switch button is pressed?

  A signal goes to the negative side of the circuit
• What is the purpose of connecting the GND of the Arduino board to the float switch?

  To complete the circuit for operation
• What does `int` represent in coding?

  It represents a fundamental data type for whole numbers
• What does `void setup()` do in a program?

  It prepares and initializes variables and conditions
• What is the function of `void loop()`?

  It runs continuously after `setup()` has executed
• What does `digitalRead()` do?

  It checks the state of the float switch
• What is the purpose of `Serial.print()`?

  To send data to the serial monitor
• What does `digitalWrite()` do?

  It sets the state of a digital pin
• What is the purpose of the tone() function?

  To generate a square wave of specified frequency
• What does noTone() do?

  Stops the tone on the specified pin
• What are the steps to configure a float switch with an Arduino?

  1. Connect GND of Arduino to float switch GND.
  2. Connect float switch pin to digital pin on Arduino.
• What are the coding steps for a float switch program?

  1. Variable Declaration
  2. Initialization with `void setup()`
  3. Execution with `void loop()`
  4. Use `digitalRead()` and `digitalWrite()`
• What are the coding steps for a float switch with an LED?

  1. Variable Declaration
  2. Initialization with `void setup()`
  3. Execution with `void loop()`
  4. Use `digitalWrite()` to control LED
• What are the coding steps for a float switch with a piezo buzzer?

  1. Variable Declaration
  2. Initialization with `void setup()`
  3. Execution with `void loop()`
  4. Use `tone()` and `noTone()` for sound
