1604A LCD Blue Screen 4 Row:
- With 16 columns and 4 rows for text display, the 1604A LCD is a 16x4 character display. It's often utilized in many different electronics projects, particularly those that involve microcontrollers like Arduino.
Here are some of its main attributes along with usage advice:
- Controller: The HD44780 or a comparable controller, which is widely supported by libraries, is usually used.
- Interface: It can be interfaced with an additional module via I2C or using parallel communication (4- or 8-bit mode).
- Backlight: Due to its aesthetically pleasing and readable nature, the blue screen with white writing is a popular option.
- Simple Arduino Setup
To begin using an Arduino, you can take the following actions:
Materials Needed:
- Arduino board (e.g., UNO or MEGA)
- 1604A LCD
- Potentiometer (10k Ohm) for contrast adjustment
- Jumper wires
- Breadboard
Wiring:
- Connect the LCD pins to the Arduino as follows:
- VSS to GND
- VDD to 5V
- V0 to the middle pin of the potentiometer
- RS to digital pin 12
- RW to GND
- E to digital pin 11
- D4 to digital pin 5
- D5 to digital pin 4
- D6 to digital pin 3
- D7 to digital pin 2
- A (Anode) to 5V through a current-limiting resistor
- K (Cathode) to GND
