Jhd-2x16-i2c Proteus < PRO — Playbook >

Connect the VDD/VCC pins of the IC and LCD to a POWER terminal (+5V) and VSS/GND pins to a GROUND terminal. The I2C Bus:

lcd.setCursor(0, 1); lcd.print("Proteus Sim OK"); jhd-2x16-i2c proteus

By eliminating the 16-pin parallel bottleneck down to a 2-wire serial bus, this approach drastically frees up microcontroller GPIO pins for sensors and peripherals. Understanding the JHD-2X16-I2C Module Connect the VDD/VCC pins of the IC and
