Popular 16x2 character LCD module, 1602A LCD can show 32 ASCII characters in two rows. It frequently works with microcontrollers such as Arduino. Pinout: GND: Ground pin. VCC: Voltage-controlled supply (usually linked to 5 volts). Vo (LCD Contrast): Modifies the contrast by employing a potentiometer and a voltage divider network. Register Select (RS): Distinguishes data (HIGH) from commands (LOW). R/W (Read/Write): For write mode, this is usually maintained low (an output device is an LCD). E (Enable): Turns on the display (incoming data is processed by HGH). Data Bus D0-D7: Transports 8-bit information for character display. Characteristics: Display Dimensions: 2 rows, 16 characters wide. Characters Colour: Blue background with white characters. Included is a single LED backlight that may be dimmed using a resistor or PWM. Specification: LCD Mode: Positive, Translative, STN Blue is the display colour. Driving Configuration: 1/5 bias, 1/16 duty Method of Control: I2C Viewing Angle: 6H
