Make sure that all 20 holes line up with the holes on the perf board. Then glue the perf board inside of the box with some hot glue. Take the perf board off and drill where the markings are on the project box. Next mark the 20 holes on the top of the box through the board with a sharpened pencil. An easy way of doing this is by marking the holes where the leads poke out of the perf board and then taping the board to the top of the project box. Next, drill 20 holes with a 1/16" drill bit for the leads on the top of the project box. Use a straight edge and a knife to score the outline along the lines, then break off the access material by placing the perf board in a vise or on the edge of a table, then apply pressure till the scored sides snap off. Start by marking an outline of a square with a Sharpie that is slightly smaller than the interior sides of project box on the perf board. The 4x4x4 LED cube is starting to take shape! Straghten another length of craft wire and cut and bend four sections that will later connect the four layers to the perf board. Start by soldering the leads in the center, then work out to the leads on the edge. Next, take the four LED layers and solder the negative leads together by stacking the individual layers on the top of each other. Now your first LED layer is finished! Follow this step three more times to end up with four layers. Make sure to do this evenly to avoid bending or damaging the layers structure. After the hole positive layer is soldered together, flip the box over and start pushing the tips of the LEDs out of the holes in the jig. This can be solved by straightening a length of craft wire by pulling both ends of the wire with pliers and trimming two 1" sections that are then soldered in place. Now, you might have noticed that there are two gaps in the layer of the positive leads. Solder all of the positive leads together and trim off the access of the leads. The red arrows represent the positives(anodes) likewise the blue arrows represent the negatives(cathodes). This may sound tedious but in the end this will safe-guard your your project! Next, insert 16 LEDs into the holes and bend the leads to the direction of the arrows using needle nose pliers. Take the 64 LEDs and test them to ensure that they all work using a button cell battery. Please click on the orange vote ribbon in the upper right-hand corner of this Watch The Video:īesides the fun of making and posting this instructable, this project is an entry for the Tech, Teach It, and Epilog Challenge VI Contests. I programed code(sketches) for the Arduino Uno to controll the individual LEDs to display patterns for this captivating desktop light show. The hardware consists of an open-source hardware board designed around an 8-bit Atmel AVR microcontroller, or a 32-bit Atmel ARM. An Arduino is a single-board microcontroller, intended to make the application of interactive objects or environments more accessible. The cube has 64 green LEDs which make up it's 4 layers(positives) and 16 columns(negatives). Techatronic.In this tutorial I'll show you how to make a 4x4x4 LED cube for around $15.00. NOTE: Please upload the given code to the Arduino. Please handle the soldering iron very carefully.Ĭolumn 9 -> digital-13 Code for the Project You have to solder the LEDs with each other. There are a total of five amazing patterns. The LEDs glow very fast and in such a way that we observe the different patterns on the cube. You can use an external power supply from batteries or a USB cable to run the pattern. A simple LED pattern with Arduino is given here, you can take a reference from it. You have to specify the location of the LED which you want to turn on. The cube we made is a 3x3x3 LED Cube with a total of 27 LEDs. Complete the circuit and then upload the given Arduino code. You can learn 10+ basic projects and sensors interfacing with well-explained code from our E-book on Arduino. You need a total of 27 LEDs and all of them are of the same color so that the pattern we observe looks more amazing. In our previous article, we have discussed the making of a 4x4x4 LED Cube so you can also check it out. Basically, there are many variants of Arduino boards available in the market but in this project, we use an Arduino UNO board. You can check out more cool working projects based on Arduino if you like this one. Several layers of the connected LED bulbs are placed one above another. An LED cube is a 3-D arrangement of many LED bulbs that are connected with each other. In this article, we are going to teach you how you can make your own 3x3x3 LED Cube using Arduino.
