LED Matrix

About: Things made with crappy tools, an impatient maker and in an imperfect manner in a rush, but just done well enough to call projects

This is a 8x8 LED matrix made using WS2812 LEDs and an ESP8266 Microcontroller

This project was inspired by : https://www.instructables.com/id/Make-Your-Own-10x...

Step 1: Wiring Up WS2812 LEDs

In short, the LEDs were chained up in a long strip that was shown above. (Row by row, and the end of 1 row connected to the start of the next row)

(Ignore the missing 4 LEDs, I ran out of LEDs. They do not make a huge difference anyway)

After that, the LED strip was connected to a microcontroller (ESP8266)

Step 2: Acrylic (and Wood) Case

2 pieces of black acrylic were cut (with a knife), bent(using a soldering iron) and hot glued together(with a wooden stick as support) to form the sides of the matrix

A clear piece of acrylic and tracing paper behind it was used as the front screen, put in front of the matrix to diffuse the LEDs and protect the electronics.

Wooden sticks were cut in such a way that they can fit together and form dividers between the LEDs. This prevents the colours from the LEDs from diffusing into one another can ruin the clarity

After that, put the LED matrix, divider and clear acrylic in the black acrylic side piece

Step 3: Software

I used the Adafruit NeoMatrix Library, the NeoMatrix GFX Demo.

You could code other software to connect the ESP8266 to Wifi and gather data.
