arduino led strip
If you remember about two years ago, I posted a project called the music reactive desk lamp and today we will be revisiting that project. So let me tell you what I have in mind: okay, here’s. The plan. Imagine a room, for instance, the living room with a tall floor, lamp standing in each corner. The center of the room has your regular seating area with some speakers. Next to the television in one side of the room, the sound emits from the speaker and enters a portable microphone that can be placed on a table or moved anywhere near a sound source. The microphone transmits the sound signals to the lamps wirelessly, which in turn makes the lights on the lamp, react to the sound and illuminate the entire space that’s the plan to create the lamp. I have four of these aluminum channels. We are going to place the LED strip in the middle of the channel, but to diffuse the light. We’Ll have to use some acrylic glass. We have to go cut smaller strip of the acrylic to fit on top of the channels Music, as the acrylic glass is super, clear and transparent, and I want the lights from the LEDs to be more diffused, and even I have to sand the glass for a While also this fixes the rough edges that the table so creates, I started with a low grit of around 80 and move my way up all the way to 600 grit.
I did this for four different strips of acrylic, so that I can make four different lamps. Now we can move on to the LED strips in this project. I will be using quite a few components. I will put a link for all of them in the description box of this video. This is an individual addressable RGB strip with 144 LEDs per meter. If you’re unfamiliar with individual addressable RGB s, all it basically means is that each individual LED can have a different color than its neighbor and that’s quite handy for cool light effects with the adhesive that comes on the back of the strips and some extra hot glue. For a good measure, I can secure the LED strips to the bottom of the aluminum channels, I’m, also killing off the cables on one side. Now that the LEDs are in place I’m going to use quick drying epoxy glue to secure the acrylic to the top of the aluminium, I apply the glue on the top of the edges and hold the acrylic stable for a couple of minutes, and this was a Bit hard to do on my own, so martina help me out thanks: martina Music as a housing, poor, the electronics and as a nice base for the lamp I’m going to use this slab, as you can see, it’s quite thin, but we’ll get smaller strips glue them Together and hopefully we’ll get a nice and sturdy block, I tested different sizes and decided.
I was going for 10 by 10 centimeter large blocks or about 4 by 4 inches. I lost the footage of cutting the strips, but I adjusted the table saw to the right thickness and then I used a miter saw with a jerry rigged, stop block to cut the lengths, and I need quite a few of these. The block will have 5 stacked on top of each other and since I’m, making 4 blocks. I have to get 20 pieces about if you’d attempt anything like this on your own don’t forget your respirator Music Music. I glued together blocks with three pieces and blocks with two pieces to block with two pieces will be on the bottom and will be hollow in the middle to give room for the electronics, while the top three layers will have a hole that fits the aluminum channel. So it can slide into position now. I marked the center on the block and draw the outline of the aluminum channel on the wood to serve as a guide for where to cut I’m, using the drill press with a Forstner bit to cut out most of the wood. And then I wouldn’t chase. All along with some patience to get the cat right Music, I made sure the LD bar fit into the socket in the woods and I’m moving on to the bottom parts. This part needs to be entirely Hollow as to make room for the electronics by drilling holes.
In each corner I made room for the blade on my jigsaw, so I could cut out a large hole using a generous amount of wood glue between the pieces. I put one of the hollow blocks on the bottom of the block, with LED bar socket, with a large amount of clamps pressing the pieces firmly together. I can’t say it looks gorgeous at this point, but let’s wait until the glue is dry and we will see how it looks after I have run it through the belt sander Music, the woodworking for the lamp bases, is complete I’m, applying a little bit of oil. Finish on top of that sander dough, which I personally think turned out pretty clean, now let’s move on to the fun stuff. As I said before, I want the lamb to be wirelessly controlled by a microphone centerpiece that can be moved around independently. Hence these lamps need to be able to pass some messages I’m, using the we must D 1 mini Wi Fi board. For this because of its convenient small size, I will add a schematic for the soldering in the description but here’s the quick rundown. I have an LED connector that can connect to the LED strip inside the aluminium channel. I solder the positive and negative wire of these to their own solder, pad on the side of the perf board, where I will later connect a power source. Next, i connect the green data wire to the pin where the d2 connector of the Wi Fi board is placed a soldier, a path for the positive and negative from the big solder pads on the perf boards to the 5 volt pin and ground pin on the Whmis, so that the board is powered.
Lastly, I solder a connector to the solder pad that will later be used to power the entire thing to provide enough power for the LED strips I’m using a 40 watt, 5 volt power supply. I have matching plugs which the power supply can connect to, and I solder these to the other half of the connector that will connect the electronics to the power plug Music. To finish it up, I drill a hole on the backside of each wood block with a slightly smaller drill bit than the size of the power plugs. Then I use a mallet to gently tap them in place Music. A generous amount of epoxy glue around the edges of the channel will secure the LED bar in its socket. The only remaining part is to cut the perf board to size and connect and fasten the remaining cables Music I’m, making sure to mount it with a USB port down. So it will be quite easy to program it later off camera. I discovered that one of the LED strips was malfunctioning, so I ended up with three working lamps. The setup can always be extended with more lamps. Later most of the work is now done, but I also have to make the microphone module so let’s do a quick rundown of the components, a battery cell, to provide a completely wireless experience, a battery holder to hold the battery a power switch to cut off all Power and note MCU Wi Fi module.
Since I ran out of the WHMIS, it serves the same purpose: a microphone module to provide the lamps with audio data, a charge, controller to charge and discharge the battery safely. A push button to change the lamp mode of operation and a LED diode and a Gameboy button to be the status light and at the top of the push button, using the same method as before I made a wooden block. It needs to have a slot for the microphone module and the button with LED in it Music, Music. I also want to make a slot for the charging module, so this thing can be plugged in and out of a regular phone charger. Music here is the power circuit connected to the Wi Fi board and, as mentioned, find a schematic in the description of the video. If you’re interested in seeing the details, the push button is connected to the Wi Fi board, with a 10k pull up resistor to detect the button, presses, Music, Music, Music, Music, Music, Music, Music, Music, Music, so I’m, almost done all I have to do is to upload The code for the controller and for the lamps. Luckily I have already written the code, so you don’t have to watch that. But if you’re interested in that sort of thing, I will leave a link in the description. So you can check it out. There now I’m sure the big question all of you have is: how does this all work and it’s actually quite simple, to explain when I power on this controller like this, it creates a wireless network, much like the Wi Fi network, that’s in your home, which all Of the lamps will attempt to connect when it detects that all the lamps are connected, it will start sending out data.
The data it sends out depends on the mode that it’s in and if it’s in the sound reactive mode, then it will send sound data from the microphone to the lamps and the lamps will show different colors. If I press the button, I will change the modes of the lamps and the lamps will behave differently like having a static, color or fading between some different colors. And while we are on the subject of Wi Fi, it is a good point to talk about today’s. Sponsor expressvpn, if you’re worried about security of the Wi Fi you’re visiting, especially the public ones like in a cafe or in an airport, then a VPN service is really great. To have.
