In the previous Arduino project, I have interfaced a Nokia 5110 LCD Module with Arduino. It is also a graphical LCD which can display some basic bitmap images and graphics. But the issue with Nokia 5110 LCD Module is its resolution. At 84 x 48 pixels, the Nokia 5110 LCD can be used for implementing a menu-based user interface. Due to its small size, the resulting menu will be limited to 3 or 4 items per page A standard LCD requires over ten connections, which can be a problem if your Arduino does not have many GPIO pins available. If you happen to have an LCD without an I2C interface incorporated into the design, these can be easily acquired separately. The LCD displays each character through a matrix grid of 5×8 pixels. These pixels can display.

As the output current from Arduino is only 20mA, we are connecting the LED directly to Arduino without any current limiting resistor. It is advised to use a current limiting resistor just to be safe. Anode of the LED is connected to pin 13 of the Arduino while the cathode is connected to ground. Working of Arduino Tilt Sensor. A Tilt sensor is similar to a normal switch except that the current. Programming the Arduino. After connecting the LCD to the Arduino and checking the connections carefully, connect the Arduino to the PC via a USB cable. If your LCD has a backlight, this should light up. Adjust the contrast potentiometer until you can see the dots that make up the characters of the display. You can make finer adjustments to the contrast after something has been written to the display You must do this, it is not OK to just try to 'press fit' the LCD! Also watch out not to apply too much heat, or you may melt the underlying breadboard. You can try 'tacking' pin 1 and pin 16 and then removing from the breadboard to finish the remaining solder point The ARDUINO IDE allows the user to use LCD in 4 bit mode. This type of communication enables the user to decrease the pin usage on ARDUINO, unlike other the ARDUINO need not to be programmed separately for using it in 4 it mode because by default the ARDUINO is set up to communicate in 4 bit mode. In the circuit you can see we have used 4bit communication (D4-D7)
