The potentiometer connected is used to increase or decrease the backlight of the LCD. Connect the pin 8 (GND Pin) to the GND of Arduino.Connect the pin 7 (LED Pin) to the middle pin of 1k potentiometer through 330 ohm resistor and connect the other two pins to the VCC and the ground.Connect the pin 6 (VCC Pin) to the 3.3V pin of Arduino.Connect the pin 5 (CLK Pin) to the pin 3 of Arduino through the 10K resistor.Connect the pin 4 (DIN Pin) to the pin 4 of Arduino through the 10K resistor.Connect the pin 3 (D/C Pin) to the pin 5 of Arduino through the 10K resistor.Connect the pin 2 (SCE Pin) to the pin 7 of Arduino through the 1K resistor.Connect the pin 1 (RST Pin) to the pin 6 of Arduino through the 10K resistor.If you will operate the Nokia 5110 Arduino without the resistors, then it will work but the life span of the LCD will decrease. The Nokia 5110 LCD requires 3.3V to operate, so we will have to use resistors to convert the 5V into 3.3V. The circuit diagram for Nokia 5110 Arduino interfacing is shown below. In the first example, we will simply print the data on the Nokia 5110 LCD. The required components for the Nokia 5110 Arduino are as follows Low means command mode and high means Data mode. The pin out of the Nokia 5110 LCD is as followsĭ/C: (Data/Command): This is the mode select pin. You just have to connect some wires and you are ready to go.īefore going into the examples, first take a look at the pin out of the Nokia 5110 LCD. It is cheaper and very easy to use with the micro-controllers. The Nokia 5110 LCD is a great choice when it comes to display data. First, we will simply show some data on the screen and in the second example we will read from the DHT22 temperature and humidity sensor and will show the readings on the Nokia 5110 LCD screen. You will learn the Nokia 5110 Arduino interfacing with the help of two examples. In this article, we are going to interface the Nokia 5110 LCD with Arduino.
