Component Name: DIY Conversion of Energy Science Experiment by LED Alarm Clock using PotatoOverview:This innovative component combines an LED alarm clock with a potato-based energy harvesting system, allowing users to generate electricity from a potato to power the clock. This experiment is an engaging way to demonstrate the principles of electrochemistry and sustainability.Components:LED Alarm Clock Module
Potato
Copper Wire (insulated)
Zinc Nail
Small Piece of Metal (e.g., iron or copper)
Electrolyte (e.g., lemon juice or saltwater)Setup and Connection:1. Connect the copper wire to the zinc nail, leaving a small portion of the wire exposed.
2. Insert the zinc nail into the potato, making sure it doesn't touch the copper wire.
3. Connect the small piece of metal to the exposed copper wire.
4. Place the LED alarm clock module near the potato, ensuring it's not in contact with the potato or the electrolyte.
5. Connect the clock module to the metal piece, allowing the generated electricity to power the clock.Code Examples:Example 1: Basic Power On/OffIn this example, we will use an Arduino board to demonstrate the concept of powering the LED alarm clock using the potato-based energy harvesting system.```c++
int clockPin = 2; // Assign the clock module's VCC pin to digital pin 2void setup() {
pinMode(clockPin, OUTPUT);
}void loop() {
digitalWrite(clockPin, HIGH); // Power on the clock module
delay(5000); // Wait for 5 seconds
digitalWrite(clockPin, LOW); // Power off the clock module
delay(5000); // Wait for 5 seconds
}
```Example 2: Real-Time Clock DisplayIn this example, we will use a microcontroller like ESP32 to read the time from the LED alarm clock module and display it on an LCD screen.```c++
#include <WiFi.h>
#include <LiquidCrystal_I2C.h>#define CLOCK_SDA 21
#define CLOCK_SCL 22
#define LCD_SDA 18
#define LCD_SCL 19LiquidCrystal_I2C lcd(0x27, 16, 2);void setup() {
Serial.begin(115200);
lcd.init();
lcd.backlight();
}void loop() {
int hours, minutes, seconds;
// Read time from the clock module
hours = readHour();
minutes = readMinute();
seconds = readSecond();
// Display time on the LCD screen
lcd.setCursor(0, 0);
lcd.print("Time: ");
lcd.print(hours);
lcd.print(":");
lcd.print(minutes);
lcd.print(":");
lcd.print(seconds);
delay(1000); // Update every second
}int readHour() {
// Implement the function to read the hour from the clock module
}int readMinute() {
// Implement the function to read the minute from the clock module
}int readSecond() {
// Implement the function to read the second from the clock module
}
```Example 3: Energy Harvesting MonitoringIn this example, we will use a voltage sensor to monitor the voltage generated by the potato-based energy harvesting system and display the readings on a serial console.```c++
const int voltagePin = A0; // Assign the voltage sensor to analog pin A0void setup() {
Serial.begin(115200);
}void loop() {
int voltageReading = analogRead(voltagePin);
float voltage = voltageReading (5.0 / 1023.0);
Serial.print("Voltage: ");
Serial.print(voltage);
Serial.println(" V");
delay(1000); // Update every second
}
```Notes and Precautions:Handle the potato and electrolyte with care to avoid any potential electrical shock or skin irritation.
Ensure the copper wire and zinc nail are not in contact with each other or the electrolyte.
The voltage generated by the potato-based energy harvesting system may vary depending on the potato's condition and the electrolyte used.
