Welcome to the Digital Counter project using Arduino! This project is designed by Prince Kushwaha from COSM Electronics.
The Digital Counter is an Arduino-based project that leverages a Liquid Crystal Display (LCD) and EEPROM to create a simple, yet functional counting device. The counter allows for incrementing, decrementing, and resetting the count with the help of push buttons, and retains the count even after a power cycle using EEPROM memory.
- Increment and Decrement Count: Use buttons to increase or decrease the count displayed on the LCD.
- EEPROM Storage: The current count is saved to EEPROM, ensuring it is retained even when the power is off.
- Reset Functionality: A reset button clears the count and sets it back to zero.
- Visual and Audio Feedback: The LCD provides visual feedback of the count, and a buzzer indicates when the reset button is pressed.
- Arduino Board: Any standard Arduino board (e.g., Uno, Nano).
- Liquid Crystal Display (LCD): 16x2 LCD with I2C interface.
- Push Buttons: Three push buttons for increment, decrement, and reset.
- Buzzer: For audio feedback on reset.
- Connecting Wires: For making connections between components.
- Breadboard: Optional, for easier prototyping.
- bt_up: Connect to A0 (Increment button)
- bt_down: Connect to A1 (Decrement button)
- bt_reset: Connect to A2 (Reset button)
- buzzer: Connect to pin 8
- Wiring: Connect the LCD, buttons, and buzzer to the Arduino as per the pin configuration.
- Library Installation: Ensure the required libraries (
Wire.h,LiquidCrystal_I2C.h,EEPROM.h) are installed in your Arduino IDE. - Upload Code: Upload the provided Arduino code to your Arduino board.
- Increment Count: Press the increment button to increase the count.
- Decrement Count: Press the decrement button to decrease the count.
- Reset Count: Press and hold the reset button to reset the count to zero, indicated by the buzzer sound.
- The current count will be displayed on the LCD and saved to EEPROM automatically.
- The counter is designed to handle counts from 00000000 to 99999999.
- Make sure to debounce the buttons for smooth operation.
- Ensure proper power supply to the Arduino and connected components to avoid inconsistent behavior.
This project is open-source and available for anyone to use and modify. Contributions and improvements are welcome!
