Arduino Beginner’s Course Lesson 5– Installing and Using Libraries

Arduino Beginner’s Course Lesson 5– Installing and Using Libraries

You can download our e-book ‘Learn Arduino’ from this link Libraries are an essential part in the Arduino world. They are what makes Arduino so easy to use. Libraries are written to encapsulate complex functions and expose them as simple function calls to the user. For example to switch a pixel on and off in

ADDRESSABLE 7 SEGMENT DISPLAYS

ADDRESSABLE 7-SEGMENT DISPLAYS MAY MAKE MULTIPLEXING A THING OF THE PAST

[Sean Hodgins] has a knack for coming up with simple solutions that can make a big difference, but this is one of those “Why didn’t I think of that?” things: addressable seven-segment LED displays. [Sean]’s design is basically a merging of everyone’s favorite Neopixel RGB LED driver with the ubiquitous seven-segment display. The WS2811 addressable RGB

RGB LED Grid 2

RGB LED Grid

This project involved creating a red, blue, green (RGB) light emitting diode (LED) matrix that displayed the colors of the rainbow. The colors of the rainbow were chosen to show the full color spectrum that the LEDs are capable of, while still giving distinct variation within the LED matrix. In this project, each diagonal of

ESP8266 Wifi enabled 8×64 pixel LED matrix display

ESP8266 Wifi enabled 8×64 pixel LED matrix display

This project is a modification of my previous Bluetooth-enabled LED matrix display project, which used 8×64 monochromatic LED matrix (total 512 LEDs) for displaying scrolling text message. The original project used Bluetooth for display data transfer from a smartphone, but this one now uses Wifi. The display message is sent through web browser to a ESP8266
