3D Printed Arduino Halloween Décor

When the full moon is shining and the wolves are howling, it's time for Halloween's spooky spectacle. The snickering grins of jack-o'-lanterns glow from lit porches. Kids skip down the block in spooky costumes, carrying bags full of candy and shouting "Trick or Treat!". The Nightmare Before Christmas is almost here... Do you see dead people???

Alright Enough of that, in this Spooktacular video I am going to create an Arduino based 3D printed Halloween Décor. It's super easy, fun and spooky....

Project 14 - Automatic Fish Feeder

Since the class has completed all the assignments from the Arduino projects book, we're moving onto more advanced projects we came up with on our own for the rest of the semester.

My first project is an Automatic Fish Feeder! This one is designed to release one feeding 12 hours after starting. Perfect for a weekend away to keep your fish happy!

expand the post to see how to make it. This one is really long since I'm sharing how I built everything as well as some of my thought processes.

Needed Materials:

Electronic parts:

• LCD

• 220 Ohm resistor

• Servo

• Potentiometer

• Capacitor

• Long Male/Female wire extenders

Building materials:

• Thin cardboard (I used a soda can box)

• Glue stick

• Bobby pin

• Adhesive dots

• Electric tape

• Printed decorations (Optional, just for aesthetics)

How It's Made:

Using thin cardboard as my main building material, I traced the footprint of the Arduino + breadboard base and eyeballed how tall the sides should be. I'll include measurements below so you don't have to guess like I did. I also made sure to leave room for the servo to poke out as well as a spot for the power cable to be plugged in.

I used an adhesive dot to stick the servo to plastic base my Arduino is on.

the front panel is a separate piece of cardboard. I traced the LCD's footprint onto the front and cut it out with a knife. The thin cardboard wasn't strong enough to hold the weight of the screen, so I made a second front panel and glued it to the first. I also left room around the edges when I was cutting out so I would have surface area to glue things together.

The food receptacle is traced from a pencil sharpener I had on hand, so I'll include the measurements in my mockup for your pleasure. It's just a rectangle with an open top and bottom. Just for fun, I glued a little strip of colorful cardboard to the bottom edge of the box.

For the trap door on the bottom of the food bin, I traced the bottom of the rectangle and cut out two. Cut the wavy leg off a bobby pin. Glue the remaining straight leg between the two cut outs, make sure it's off center(as seen in picture X). Use electric tape to secure the rounded part of the bobby pin to the little servo arm. Stretch the tape as you put it on to make sure it's secure.

Finally, I spiced up the outside of the build with some labels and pictures. I have a small thermal sticker printer, but any printed or hand written markings will do. I stuck the fish image to a cardboard scrap and cut it out before gluing it above the LCD. Having it come off the edge of the box adds a lot of visual interest to an otherwise boring build.

Board:

The Code:

Once the Arduino turns on, it starts counting up until the dispense time - start time = 0. Then the servo will rotate it's arm to 180° and dump the food into your fish tank. The LCD screen will display a welcome message before showing the time remaining until the food gets dispensed. For the demonstration, I changed the code to dump the food after 10 seconds and display the time remaining in seconds. You can comment that out and comment in the 12 hour pre programmed time if you want to actually use this build.

Buzzer and Arduino: How to Create Simple Sounds and Melodies

Do you want to add sound to your Arduino projects? A buzzer is a simple component that can produce different tones and melodies. In this tutorial, we’ll show you how to use a buzzer with an Arduino board and guide you through the steps to create simple sound effects and melodies.

Step 1: Get the Materials To get started, you’ll need the following components:

Arduino board

Buzzer

Breadboard

Jumper wires

Step 2: Connect the Buzzer to the Arduino Board Connect the positive (+) pin of the buzzer to pin 8 of the Arduino board and the negative (-) pin to the ground (GND) pin.

Step 3: Write the Code (get the code for using the buzzer with Arduino)

Step 4: Upload the Code to the Board Upload the code to the Arduino board via the USB cable.

Step 5: Experiment with Different Tones and Melodies Once you’ve successfully uploaded the code, you can experiment with different tones and melodies by changing the delay time or adding more tones.

Conclusion Using a buzzer with an Arduino board is a simple way to add sound to your projects. By following these steps, you can create your own unique sounds and melodies. So, why not give it a try and add some fun and creativity to your Arduino projects? If you have any questions or suggestions, feel free to leave them in the comments below.

hiiiii

tested an ips tft display i have since ahh... spring. not so long ago ive got an idea to embody a scene from 8:11, when ryker got splashed with blood at the screen with leon.

its a wip now but i hope i would not be eaten by exams due this week..

heres more photos of display, but now in a dark.

less interesting - while writing the code it turned out that i didnt have the library i needed, which wasn't even in the built-in ide library search. so i went to github, and there it turned out that the library was outdated and in its place there was a new one (since 2020 ig), the version of which was already downloaded. i had to download the archive and upload it to ide to make everything work. also, i need to edit the program a little and clean it from unnecessary #includes, so there is no confusion.. and i also used a breadboard

Нет - это не гирлянда. Заливаю прошивку в умную розетку. Теперь она настолько умная что держит сайт и больше не дружит с китайскими облаками ( да и вообще с любыми кроме моего собственного)

Anyone wanna see a dope robot my class made?

[ordinarymagician2000]

Today I fixed up my Mini-Hakkero prop for my cosplay!

Originally made it last year, but bringing it to cons ended up killing my terribly loose solder and crimp jobs for the admittedly janky internal wiring. For my fix I ended up having to skip 3 unreachable LEDs and attach new wires to the LED spiral (the shell stuck too much together and I could not reach under the battery holder anymore). A compromise, but one that ended up looking alright.

It's not the cleanest thing, but it was my first ever arduino project and with the new pattern i set up, it works decently enough as a cosplay prop :)

DIY Digital Laser Ruler Tutorial with VL53L0X GY-53, SSD1306, and Wemos ...

[numbpill]

need a bit of advice on something rather new to me... i have been DYING to get into some semblance of diy electronics/robotics, specifically regarding the idea of building a flipper zero knockoff with a raspberry pi/esp32/arduino. or a hack rf one ripoff, etc. u get it? i wanna make a lil handheld pwnagotchi pet style device for rolljam rf shit, something that can copy and paste and send and receive rf signals, but homemade by my self....

please if anyone has experience, resources, ideas, anything at all= hit me up right now immediately asap today please.... i am so passionate and ready to do this please help me make device go beepboop

Numpad Jr

My thinkpad doesn't have a numpad and could use something more portable than the average USB ones, so… just made one! Used Kailh square mouse buttons and an Arduino Pro Micro.

Sure, tactility's compromised due to size… but look at the cute lil' thingy lol.

realized nobody is gonna know how to read my geiger counter i built in that picture. it clicks and blinks the leds when there’s radiation. i have the potentiometer all calibrated and everything and have tested it extensively on uranium glass there’s simply no radiation coming out of that tv
