ATmega328 Microcontroller

Features

The ATmega328 is an 8-bit microcontroller from Atmel (now part of Microchip Technology). It operates at a clock speed of 16 MHz and includes 32 KB of Flash memory for program storage, 2 KB of SRAM for data handling, and 1 KB of EEPROM for non-volatile data storage. With 23 general-purpose I/O pins, it provides ample connectivity for sensors, actuators, and other peripherals.

Flexibility

The ATmega328 is known for its versatility and ease of use, making it a popular choice for both beginners and experienced developers. It supports programming via the Arduino IDE, which offers a vast library of pre-built functions and a large community for support.

LCD 16×2 Display

Overview

The 16×2 LCD display can show 16 characters per line on two lines, making it suitable for displaying text, numbers, and simple symbols. It uses the Hitachi HD44780 controller, which is compatible with a wide range of microcontrollers, including the ATmega328.

Interface

This display typically interfaces with the microcontroller using 4-bit or 8-bit parallel communication. It requires a few digital pins from the microcontroller for data and control signals, allowing for efficient and clear display of information such as sensor readings, status messages, and user prompts.

Power Supply

Voltage Requirements

The ATmega328 and the LCD 16×2 display both operate at 5V, making it straightforward to provide a single power source. The system can be powered via USB, a battery pack, or a dedicated 5V power adapter. Ensuring stable power supply is crucial for the reliable operation of the microcontroller and the display.

Power Management

An onboard voltage regulator can be used to manage the power supply, providing consistent voltage levels to the components. This helps protect the system from voltage spikes and ensures smooth operation, especially when running complex or long-duration tasks.
