CIPAD_10. Suite de la leçon 9: Indicateur de niveau d'eau, pompage automatisé, 2 modes Version 3

Introduction

This tutorial focuses on programming an automated water level indicator and pump system, as discussed in Daniel Talbot's CIPAD lesson 10. Building on the previous lesson, this guide provides a step-by-step approach to implementing version 3 of the water level indicator, enabling effective and automated water management.

Step 1: Understanding the Components

Before diving into programming, familiarize yourself with the essential components of the project:

• Water Level Sensor: Detects the water level in a tank.
• Arduino Board: Acts as the brain of the system, processing inputs and controlling outputs.
• Pump: Automated water pump for filling or emptying the tank.
• Power Supply: Ensure adequate power for the pump and Arduino.

Step 2: Setting Up Your Environment

To get started with programming the water level indicator, set up your development environment:

1. Download and Install the Arduino IDE: Ensure you have the latest version of the Arduino Integrated Development Environment (IDE) installed on your computer.
2. Connect the Arduino Board: Use a USB cable to connect your Arduino to the computer.
3. Install Necessary Libraries: Depending on your components, you may need to install specific libraries to facilitate communication between the Arduino and the sensors.

Step 3: Programming the Water Level Indicator

Now it's time to write the code for your water level indicator. Here’s a basic structure to get started:

1. Define Variables:

   • Use a String type variable to store messages or states.
   • Create an array to manage multiple sensor readings if necessary.

   String message;
   int sensorReadings[5]; // Example array for storing sensor values
   

2. Setup Function:

   • Initialize your serial monitor for debugging.
   • Set the pin modes for sensors and pumps.

   void setup() {
       Serial.begin(9600);
       pinMode(sensorPin, INPUT); // Replace sensorPin with actual pin number
       pinMode(pumpPin, OUTPUT);   // Replace pumpPin with actual pin number
   }
   

3. Loop Function:

   • Implement the logic to read sensor data and control the pump.

   void loop() {
       int waterLevel = analogRead(sensorPin);
       if (waterLevel < threshold) {
           digitalWrite(pumpPin, HIGH); // Turn on pump
           message = "Pump ON";
       } else {
           digitalWrite(pumpPin, LOW); // Turn off pump
           message = "Pump OFF";
       }
       Serial.println(message);
       delay(1000); // Adjust delay as necessary
   }
   

Step 4: Implementing Control Structures

Incorporate control structures to enhance your program:

• If Statements: Use if to check conditions and control the pump based on water levels.
• Else Statements: Use else for alternative actions when conditions are not met.
• Switch Case: Consider using switch for managing different operational modes if applicable.

Common Pitfalls to Avoid

• Ensure all connections are secure to prevent intermittent issues.
• Check for correct sensor calibration to get accurate readings.
• Properly handle power supply requirements to avoid damage to components.

Conclusion

This tutorial provided a structured approach to programming an automated water level indicator and pumping system using Arduino. By following these steps, you can create a functional and efficient water management solution. As a next step, consider experimenting with different control logic or integrating additional sensors for enhanced functionality.
