To display the sum of money inserted into the coin acceptor on an LCD display through I2C, you will need to integrate the following steps:
Here is some sample code to help you get started:
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 16, 2); // Initialize the LCD display module
int totalAmount = 0; // Initialize the total amount of money inserted to zero
void setup()
{
Wire.begin(); // Initialize the I2C bus
coinAcceptorSetup(); // Initialize the coin acceptor module
lcd.init(); // Initialize the LCD display
lcd.backlight(); // Turn on the backlight
}
void loop()
{
if (coinInserted())
{
addCoinValueToTotal(); // Add the value of the inserted coin to the total
showTotalAmount(); // Display the updated total on the LCD display
}
}
void addCoinValueToTotal()
{
// Code to read the value of the inserted coin and add it to the total
}
void showTotalAmount()
{
lcd.setCursor(0, 0); // Set the cursor to the first line of the display
lcd.print("Total amount: $"); // Display the label for the total amount
lcd.print(totalAmount); // Display the actual total amount value
}
Note: This code is just a framework, and you will need to fill in the details for the coinAcceptorSetup()
and coinInserted()
functions according to your specific hardware and software requirements.
