Description<\/h2>\n
The Nokia 5110 LCD is very\u00a0popular among the Arduino tinkerers. These modules are used on wide variety of applications that\u00a0require some sort of interface or display data to the user.<\/p>\n
These modules are very cheap and you can use them with\u00a0any microcontroller (MCU).<\/p>\n
Specifications Nokia 5110 LCD<\/strong><\/p>\n You can purchase these modules from eBay for just a few dollars.\u00a0Click here to\u00a0see Nokia 5110 LCD for Arduino\u00a0on eBay<\/a>.<\/p>\n You need the following components to make this example:<\/p>\n Here\u2019s the library\u00a0you need for this project:<\/p>\n 1) RST – Reset The Nokia 5110 LCD operates at 3.3V. So you can’t connect the Arduino Uno digital pins directly. Read this blog post<\/a> to learn how you can level shift the signals from 5V to 3.3V.<\/p>\n I’ll be adding some resistors in series with the data signals to protect the\u00a03.3V lines.<\/p>\n Using Logic Level Converters to switch from 5V to 3.3V is the best option to interact with this LCD.<\/p>\n After installing the PCD8544 library in your Arduino IDE, you can find the sketch below in File > Examples >\u00a0PCD8544 > HelloWorld.<\/p>\n View raw code<\/a><\/p>\n Demonstration<\/strong><\/p>\n After you upload the\u00a0sketch your LCD should print the words: “Hello, World!”.<\/p>\n I hope you found this guide useful.<\/p>\n Share this post<\/strong> with a friend that also likes electronics!<\/p>\n You can contact me by leaving a comment.
