Intro: How to Use a Nokia 5110 84X48 LCD Display With Your Arduino (It's Easy and Cheap!)
It's cheap and easy to add an 84X48 LCD to your Arduino project. These Nokia 5110 displays are surplus from the Nokia phones of the late 90's. While the tech is old, it makes a fantastic backlit display for your Arduino projects. There is a ton of library support too.
The cost - cheap! You can buy these displays from Adafruit and Sparkfun for $10. If you are really a cheapskate, these LCD's can be found on eBay for $3 apiece, shipped direct from China.
Watch the video to learn all about the LCD, libraries, hooking up the LCD to your Arduino, and writing the code to make it work.
