simple board to control cctalk devices with arduino

You should find it on the back of the LCD connected to pin 15 (Anode). Most LCDs have a built-in series resistor for the LED backlight. In order to test the display, you will need to make the connections as shown in the figure below. Symbol Connection Function 1 VSS GND Arduino Signal ground 2 VDD 5 V Arduino Logic power for LCD 3 V0 10 kΩ potentiometer Contrast adjustment 4 RS Pin 2 Arduino Register select signal 5 R/W GND Arduino Read/write select signal 6 E Pin 3 Arduino Operation enable signal 7 – 14 D0 – D7 – Data bus lines used for 8-bit mode 11 – 14 D4 – D7 Pin 4 – 7 Arduino Data bus lines used for 4-bit mode 15 A (LED+) 5 V Arduino Anode for LCD backlight 16 K (LED-) GND Arduino Cathode for LCD backlight You will only need to change the size specifications in your Arduino code. These LCDs are available in many different sizes (16×2 1602, 20×4 2004, 16×1 etc.), but they all use the same HD44780 parallel interface LCD controller chip from Hitachi. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to products on.

I therefore like to use them with an I2C interface module mounted on the back.

As you will see, you need quite a lot of connections to control these displays.
