void LCD_init(void) delay_ms(50); // Power-up wait
: Place two 4.7kΩ resistors on the schematic. Connect one from SCL to +5V (VCC), and the other from SDA to +5V (VCC).
Displaying live temperature, humidity, and pressure data from sensors. jhd2x16i2c proteus exclusive
That’s it. No resistors, no potentiometer.
Connect SDA to the corresponding SDA pin (e.g., A4 on Arduino Uno). void LCD_init(void) delay_ms(50); // Power-up wait : Place
Write your control program in your IDE and export the compiled .hex or .elf binary file.
If you are simulating hardware designs, is the go-to software. However, the JHD2x16i2c doesn't always work out of the box in Proteus if you are unfamiliar with its specific configuration. That’s it
The standard LiquidCrystal.h library does not work for I2C modules. You must use LiquidCrystal_I2C.h or the specific DFRobot_LCD.h library designed for I2C, which is often recommended to avoid configuration problems.
The JHD2x16 in Proteus often defaults to an address of 0x76 or 0x7E (depending on the exact library version), whereas real-world modules usually default to 0x27 or 0x3F .
