Connect 4 With Strip Led Arduino and 3d Print

We created a connect 4 game using a ws2811 Led strip and an arduino, the box is 3d printed.

This game is very fun to play

• Arduino Uno
• Dupont Wire
• Button
• led strip Ws 2811

3D printer and PLA plastic

hot glue

We modeled the parts in fusion 360

the matrix that will support the leds is 7 by 7, (1 line for the waiting pawn). It is printed in black to better absorb the light.

The screen is white to diffuse the light well.

A box that will contain all the LEDs, you can print it in the color of your choice (we printed it in red).

A base to receive the screen and the arduino which can also be printed in the desired color (we printed it in blue).

It is then necessary to insert the leds in the holes of the matrix, it is then absolutely necessary to follow the mapping plan (present in the attached excel table)

The map map allows you to tell the Arduino which led to light up with its position on the led strip.

We have attached a .csv table to indicate the order in which the LEDs should be installed, otherwise here is the order starting from the top left.

0 1 2 3 4 5 6

43 42 31 30 19 18 7

44 41 32 29 20 17 8

45 40 33 28 21 16 9

46 39 34 27 22 15 10

47 38 35 26 23 14 11

48 37 36 25 24 13 12

0 symbolizes the first led of the strip led

So that the leds are stable, we add a lot of hot cole.

Then we put the screen in front of the matrix.

We incorporate everything in the box of the screen.

Finally we put this screen on the base and block everything with small clips.

Connect the wires to the arduino

the strip must be connected to ground, +5v and data to pin 3 of the arduino.

The move button to the right on pin 13

The move button to the left on pin 12

The validation button on pin 11

Finally the other terminal of each button must be connected to the +5v of the arduino

Next the code...
