RGB HexMatrix – IOT Clock – DIY

RGB HexMatrix

HexMatrix is a project of Indian origin from Mukesh_Sankhla, who has created something interesting for keen on Arduino and led bright lights from these schemes. I must say that nothing do not understand in robotics and schemes that need soldering, but the data watch with led backlight definitely like me, and maybe someday I will generate such a watch.

So, HexMatrix is a LED matrix from triangular pixels: 6 of them form a hexagon. You have a huge variety of animation that is displayed on the matrix using the FastLED library. Also, as mentioned above, lamp will be embedded IOT clock.

Should work

    ESP8266 or Arduino (Uno/Nano)

  • WS2811 LED (96 LEDs)
  • 5V/2A power supply
  • 3D printing

Step 2: Connections:

  • Connect the tape with the LEDs, as shown in the drawing (for pie chart).
  • GND~-Ve
  • Vin~5V~ Ve
  • DataIn ~ Pin 2
  • Also extend the wires for power to the last led and connect them according to the circuit to prevent the power drain through the LED.

Step 3: Notes:

  • If you use Arduino, you can only show the animation on the display but can’t show the time!
  • If you use ESP8266, it can show both time and animation on the matrix.

Step 4: Build:

12

  • Put all the LEDs in the order of the snake
  • Connect all the LEDs together
  • Plug the connector into the microcontroller, a connector is taken from the other end of the line of LEDs.

Step 5: Encoding:

download link code

HExMatrix.ino:

  • Open the code in Arduino IDE.
  • Install the FastLED library in the Arduino IDE.
  • Select the type, port and upload code.

CLock1 and Clock2 codes:

  • Open the code in Arduino IDE.
  • In the code you need to make changes…
