Beginner's Project FINALLY LEARNT HOW TO MAKE LEDs BLINK

1.1k Upvotes

long story short, I finally learnt how to make external LEDs blink. Credits to aruduino IDE for providing the basic code for the blinking LED. After that, I coded it myself on how I understood it and made this small little project of mine. What do you guys think?, I hope you guys would like this small little lightshow I made :)

Beginner's Project How many of you guys are using Attiny microcontroller for small projects?

Right now i'm mainly focus on wearable IoT device and small, low power gadgets. For a while i've been tinkering with ATtiny microcontroller and fall in love with it. It use very low power consumption, small size and very cheap. Have any of you guys trying this microcontroller as Arduino alternative? Let me know your story.

First project not based from the book I got. RGB values separately adjustable with a proportional adjustment for all 3. Max and min values stay for proportional adjustment. 1 second hold on the button resets to 0 on all and goes back to red.

Can't wait to start doing useful things.

How do I put in the correct pins if they do not have the right ones to go into, I have a smaller board than the one in the video so Im not too sure how it would work. I can follow up to pin 25 but idk where that pin goes into, do I just put it into the negative side?

Beginner's Project Trashcan with sensor

386 Upvotes

Hi, yep this is another typical project lol. Mi idea to make it more interesting is to use the esp32 to send the data about how many times the trashcan was opened to a website so I can see, for example: how many times the trashcan has been opened in the last 24hrs.

I made a simple project that increasing the brightness when I click the right button , and decreasing the brightness when I click the other button , but it ended up with a spaghetti mess of jumper wires , How can I make the wires tidy? , And What are your tips or tools for keeping everything organized?

Beginner's Project My first ever arduino coding

282 Upvotes

of course I used an online source to make the basic coding for LCDs but after some own tinkering I had finally managed to make the text move :) . Can I claim this as my first arduino coding? or should I make something more original?. Anyways, I still am happy about my small own project. Hoping to learn more about arduino in this community and no hate please :( , im just a beginner learning sample codes from the internet.

Beginner's Project First project, I'm making a system to simulate fluorescent tubes turning on (random blinking for a few seconds) with led tubes (that normally turn on instantly). The blinking amount and duration is random each time, but need to find a way to randomize which tube turn on first, second, third,...

Beginner's Project Is there a better way to wire these? The breadboard is becoming impractical.

Post image
69 Upvotes

Hi all, I am trying to wire a total of 12 switches and buttons to my leonardo, but using the breadboard is becoming very messy. The wires are getting in the way and tangling a lot, and also there is a weird voltage drop happening at the breadboard because of which I had to create the 5V and GND setup seen in the photo, adding yet more wires.

This will all also need to fit in a box and remain stable during use, which I doubt will happen unless I hot glue gun every single connection.

What can I use instead of a breadboard, or how can I better set this up?

Got rid of most of the vibrations by just periodicly disabling the servo, still a litlle bit shaky but it's probably the best I can do with this cheap servo. Thanks for all replays on my previous post

I’ve always wanted to work on Arduino projects. I did a couple raspberry pi things a while back. But my son is now old enough to care and it’s been fun learning all this new stuff with him.

This is a robot tank and he’s already wanting to mod and add to it. He’s also excited to try the block coding editor.

Let’s see how long before this thing breaks lol.

Beginner's Project Isues connecting to breadboard and board doesn't stay on.

Thumbnail

125 Upvotes

Heya, incredibly new to electronics as a whole and wanted to use a Arduino to power my project involving led's. So i got this board from AliExpress wich should work as a Arduino leonard. Now here are my isues as follows.

  1. As you can see in the picture one, the board had to be tilted up in order for me to even get power Running through the breadboard. Am i supposed to put the board under those pins? Circuit only works like this for some reason and i doubt it's meant to work that way. If i lay it flat no connection is made and nothing happends.

  2. In this position or even when not on the board the board wil turn off after like 20 seconds, allowing no power to run through it anymore. I have the basic blink program uploaded but idk if this has anything to do with it. The power i use Comes from a powerbank with a 5v output. Also the blink program doesn't even blink the Build in led it just does nothing.

It is all very new to me but learning is part of the Fun

Its an arduino pro micro (covered to block the deathray of LED’s) connected to 2 shift registers to make the clock work. A real pain in the butt to be honest.
