That 's 8 for the pumpkins and 1 for the flicker bulbs that will run In standby mode. Introduction: Singing Pumpkins/ Arduino. Make sure you wire to the correct channels. On the relay find the n/o pin connect to one of the male plugs red and white wires. The pumpkin lamps/Christmas lights/whatever could be plugged into the extension cords. I only used 4. Stranded wire will be easier to work with than solid. The traces aren't made to carry large currents. However the circuit remains the same. (hardware store), Some 1/2" 6/32 machine screws. Add some fun to your Singing Pumpkins display with these silly jokes! Solder the 10k resistor to the middle pin of the transistor. They even do their version of the Time Warp dance! 10 years ago If you use the arduino to power the relay board it will suffer in power and the relays will not have a strong latch.) On the site, someone had made one of these singing pumpkin rigs, and Kerri decided that she wanted to make her own. Connect all neutral sides together. This is one party of a song! When a pin on the port is high, the relay switch closes. Tell me about your own rigs you build with this guide, or any inspirations you may get from it.Until next time ... Second Prize in the DIY Halloween Contest. The difference is what happens if something, like your body, were to come in contact with the hot wire when the light is switched off. The desire to make the relay board reusable as more than just a singing pumpkin rig lead me to come up with the design in image 1. Now it's time to place relays and solder them. Label your outlets to mark which channel they will correspond to. It makes life a lot easier if you know which outlet on the box corresponds to which channel.1.1. CAUTION!! Lets start off by saying that I am a noob to micro controllers like Arduino. Either way will allow the light to work. Locate the line pin, now connect the speakers red and white wire to this. By wirenut1980 Follow. The relay needs to be built like the other ones in this project with diode, resistors, led and transistors. You will also need some software to play the music. on Step 9. This design worked well, except I had a few concerns with it. In our circuit, the input voltage is supplied by the PC parallel port. "Leave your body and soul at the door!" It's now a good time to add the signal wires. Reply However, it doesn't help you much if you want to do an electronics project like this. i`m looking for a el cheapo way to power all of my lights but still have it look professional. That is when I realized that I had to get one and learn the whole process of programming. Will you be able to resist singing along? CAUTION!! A parallel port relay board. In the next picture I added the second resistor (330k). The wiki is packed full of ideas for DIY lighting controls: WIKI Link Also on the forum there is a Halloween sections as well: DoItYourSelfChristmas Enjoy... _8_ch_this_is_halloween_dancing_lights.pde, https://www.instructables.com/id/Singing-PumpkinsParallel-Port-Relay-Box/. 11 years ago if you will not use background music for your display simply leave this step out. I do have 2 sets of bulbs in each pumpkin. Once the arduino program starts the relay will disconnect the background music and connect the speakers to the wave shield during singing. The Groovebarbers, made up of three ex-Rockapella members, perform this fantastically CATCHY a cappella version of an old classic. I've seen commercial boxes for server hundred dollars, but that is an awesome thrift store find. I didn't invent the rig. on Introduction. This setup will allow background music to play while the pumpkins are in standby mode with flicker bulbs running. Will they be able to escape the dark force? Since the transistor switched a ground or negative I placed it so the output pin is connected to the diode negative or ground side. The unofficial theme song for Halloween is perfectly realize with this Singing Pumpkins Effect. This is the terminal that is switched by the relayNC = normally closed. Check out some of the hardware these guys have come up with. The wave shield will use pins 1, 2 ,3 ,4 ,5 ,10 Our project uses pins 6, 7, 8, 9, A0, A1, A2, A3, A4, A5 Pins 6 ,7 ,8, 9, A0, A1, A2, A3 will be used for the pumpkins flashing lights, pin A4 will be used to control the flicker bulb set and pin A5 will be used to control a relay that will disconnect the background audio and connect the wave shield to one set of speakers. The comical "Sexy and I Know It" by LMFAO has been MASTERFULLY covered by Noah Guthrie, and perfectly animated by us! You really don't want an exposed wire with wall current flowing through it anywhere near you.It was with all those concerns in mind that I came up with the design in image 2. Even though it took a lot of work the final result is well worth it! This is merely my interpretation of it. At this point I added the transistor and first resistor (10k). Use an outlet face plate and trace holes. Upload the audio file to an sd card, and upload the sketch to the arduino.SKETCH // Created by Greg Spiridakos 2011// #include #include #include "util.h" #include "wave.h" AF_Wave card; File f; Wavefile wave; // only one! I got mine at Walmart a few years back. 2. 11 years ago In the back of the stand will be the guts of the operation as seen in the pictures. Please tell me how to use porttalk!!!. Share it with us! On a less critical note, convention/codes in the US, calls for wire colors for 110 volt circuits to be assigned as follows: Green = Ground wire White = Neutral wire Black = Hot wire When more than one hot wire is used, the other hot wires may be Red, Blue or Yellow. Join in with our Singing Pumpkins as they sing Harry Belafonte's song featured in one of the funniest scenes from the movie "Beetlejuice"! If the switch is on the neutral wire, electricity will reach you and go through your body to ground. Even though relays have no polarity the diode will change that ( diodes let the juice flow one direction ) and that will keep the voltage from bouncing back where it shouldn't be. CAUTION!! So you've got this awesome relay box, now what? on Introduction, You can buy boxes that do that.. We're going be using it as a stencil, so quality doesn't matter. The Haunted Mansion's "Ghost Host" has materialized and is waiting to follow you home! On the male plug connect the red and white (left ch and right ch) together do this for both male plugs. I got a 10 pack for less than $4 at. The outlets and the relay board are mounted to the project box so there is no concern of wires being pulled during transport. Let's do the Time Warp, again! Two good explanations of relays can be found at:bcae1.com (thanks makezine)howstuffworks.comThe relays in this circuit has three terminals. Did you make this project? These next steps cover how to wire up the relay board to the outlets.Image 2 shows a diagram of how the relays and outlets will be wired. lights? IN THE MEAN TIME PLEASE USE THE OLDER VERSION OF ARDUINO SOFTWARE OR IF YOU CAN HELP WITH THE FIX PLEASE POST!! I'm really not sure if it needs to be grounded. Kinda funny, and a tiny bit scary. Do you have essentially two bulbs in each pumpkin the flicker and a regular socket light? This Instructable is mostly about how to build the relay box, but the end result is a cool Halloween decoration. A laptop is preferable for portability, but laptops with parallel ports are hard to come by these days. Halloween Pumpkin With a Moving Animatronic Eye | This Pumpkin Can Roll Its Eye! Third Prize in the Halloween Decorations Challenge. We're making some nice progress on this project. Outlets: I used 5 outlets for 8 pumpkins. This is to power the relay board. The guides I saw online for building the singing pumpkin rig were sufficient to get the job done, but I saw a few problems with them. Get your sheep suit on! The flicker bulb string will plug into it's own line that connects to the A4 pin of the arduino. In this step add the led. Less than $1. UV rays or wild animals may damage insulation, water gets in places it shouldn't. on Step 1, i found a relay board for 17$http://robokitsworld.com/index.php?main_page=product_info&products_id=213. The Set Up. I used an 12V@1A AC adapter from an old scanner. You just have to watch out because some cheaper cords don't always have the ground cable even though they have the ground pin on the plug (I don't know how these are legal to sell). Rock out to our Singing Pumpkins performing Oingo Boingo's classic 80's hit! 2 years ago This is the longest and most entertaining Singing Pumpkins Effect we have done to date. CAUTION!! 6 years ago Your display isn't complete without this collection of goofiness! Plus the ends of the cable are handy for other projects. Also the relays have their own power rating. I have one that has 6 outlets in it and it has songs built in (I think mainly christmas) but u can plug an MP3 player into it and play whatever songs u want.. they're kind of expensive but I got mine at the thrift store for like 5 bucks! We bought ours at Target and Walmart. House all the wiring for the project.3. The order that you connect the green wires to the C terminals is not important since they are all tied together in the wire-nut. However, I really wouldn't feel safe to leave it plugged-in and unattended for an entire Christmas season. Drill a hole and feed your signal wires, a plug for arduino, and audio plug through the hole.
