Since you want a method, you have two options. I recommend Option 2 for long-term reliability.
or AMPIRE16X2 : The standard 16x2 alphanumeric LCD display matrix. PCF8574 : The 8-bit I/O expander for I2C bus communication. ATMEGA328P or ARDUINO UNO : Your target microcontroller. Step 2: Schematic Circuit Wiring jhd2x16i2c proteus free
Simulating an I2C-based 16x2 LCD display reduces prototyping time and eliminates the risk of damaging physical hardware. The JHD2X16I2C is a popular 16-character, 2-line display module that utilizes the I2C serial protocol to minimize microcontroller pin usage. This comprehensive guide covers how to set up, wire, program, and troubleshoot the JHD2X16I2C LCD display within the Proteus design suite using free, accessible resources.
