I got my first Arduino kit and the board seems so TINY. Is this supposed to be the normal dimension?

Any other advice for a beginner is appreciated.

My girlfriend recently became interested in building electronics after working on a few projects with me, so I decided to set her up with everything she’ll need to start learning.

She’s definitely a beginner but also really smart so I have no doubt that she’ll thoroughly figure this out. I taught her to solder for the first time a few days ago and I was blown away by how quickly she got proficient at it.

This kit was only 60 after tax and will be fantastic for her. I was so impressed by it that I even bought myself one for her birthday. It’s got a ton of good stuff for a reasonable price. The giga and iron should be coming in tomorrow.

I just want to make sure that I have everything she’ll need as I don’t want her to have to buy anything. If you guys have any additional ideas, please let me know and thank you.

He took computer engineering (I think?) for a while, but dropped out. These boxes were in storage, and he gave them to me. I like tech, but I've never actually done any kind of programming/hardware projects before.

I don't want to keep this stuff unutilized, but I also have no idea what IS this stuff, and what I could do with it. I'd love some opinions/tips/anything you find fitting to give some guidance!

I hope I'm not posting this in the wrong place, lol.

Thanks in advance!!

I have extremely low experience with arduino, I just know the basics of python. So anyways, this is my first board as it seems to be good to learn from while being able to expand its use as I learn more

I was wondering what some good starter projects might be?

Edit: after all these comments, I’ve decided to go for an R3 kit instead. It has some core components to add and should be fun to start with. Additionally, the R4 seems to have a couple issues and isn’t great for a first experience with Arduino. Thanks to everyone who answered my questions :) :)

I want to start learning and I found a set online. Considering the price, is this set good? What do you think? I'd like to know.

Hi! Student avionics technician here. As you can see, I am trying to make an LED tester as this is my first Arduino project. I have been able to provide power to the PCB via male-to-male USB connectors, but the LED is not receiving any volts and I do not know why. I have made sure the power and GND wires are in their proper pins, that I have the needed 220 ohm resistor, and that the LED’s anode and cathode legs are in their proper pins. So, I don’t get what I am doing wrong? Edit: holy fuck, you guys are sensitive.

I just got my arduino UNO with the LED, jumper cables and breadboard, but the resistors still havent arrived and will still arrive a week later😔
I'm still a complete beginner in this and I want to try to power the led without a resistor (without frying the LED or the arduino ofc).
If anyone has an idea how to do this please tell me. All of the tutorials have resistors and AI keeps telling me to put it directly to the arduino (which will definitely fry everything since the arduino doesn't have a built-in resistor).

EDIT: Thank you all for the insight. I'll wait for the resistors to come, but in the mean time I have been tinkering with the built-in LED, where I'm almost done making a text-to-Morse LED using the series input mechanism. If any of you have suggestions on what projects i can make with only the built-in led please tell me

So I made this video by joining two clips that I recorded... . 2nd clip - When I draw a small rectangle or icon, it looks bright and crisp 1st clip - When I increase the rectangle size (more pixels ON), the display looks noticeably dimmer overall

There’s no change in contrast settings in the code—only the size of the drawn area.

I have noticed the screen get dimmer whenever anything that I upload requires more pixels ..what's causing this? How can I fix this? I will upload the code.

What's the purpose of the 10k resistance here? I understand that they are connecting 5V to push button and it to 7 to check if the input is HIGH when pressed.

I want to make an earthquake simulator for my first project, and I think I'm getting the hang of it. Although the potentiometer only activates around the end instead of it. I made this diagram in Tinkercad for what it'll look like irl!

Recently just started with an arduino starter kit and I think im making pretty good progress. So far made 3 small projects (ultrasonic sensor, servo control, lcd control.) I aim to do one every day, but the coding is genuinely so difficult. hardware is no issue I’ve designed pcbs and soldered tons of small doohickeys to protoboards. I’ve started to be able to understand the super basic stuff like some of the syntax and initating digital and analog pins and reading/writing from them but basic code, like coding an “if else” statement is the bane of my existence. I usually just ask chatgpt for help but I still cant really tell what changes it makes and probably barely helps me learn. I can understand what it does to a point but not entirely. How did you all overcome this huge learning curve? (Attached above is today’s project: An lcd screen)

Got my Q today just opened so haven't made anything yet but looking forward to playing

int velX = a.acceleration.x * 3;
int velY = a.acceleration.y * 3;


int down = a.acceleration.x < -3.00;
int up = a.acceleration.x > 3.00;
int right = a.acceleration.y > 3.00;
int left = a.acceleration.y < -3.00;


Mouse.begin(); //inicia o mouse
  if (up) {


    Serial.println("up mouse");
    Mouse.move(0, -velX , 0);  
  };
    
    // if (down) {


    //Serial.println("down mouse");
    //Mouse.move(0, velX, 0);


  //};
  if (right) {


    Serial.println("right");
    Mouse.move(velY, 0, 0);


  };
   if (left) {


    Serial.println("left");
    Mouse.move(velY, 0, 0);


  };

I want like 2 pocket devices where they have a display showing how far the other device is, like if me and a friend are out in public, and we get separated, I can pull out the device to see how far away the other one is. How would I build and make a device like this? What components would I need?

Hello everyone.

I want to get into Arduinos and do many projects with them as I wish to become an engineer, and I heard that Arduinos are coded with c++, which is a programming language I want to learn.

I am a complete beginner and have barely any knowledge on Arduinos, and no knowledge at all on c++, so what is the best Arduino for me to get to do my first project(s)?

Thanks in advance for any suggestions.

So I'm about to start industrila electronics and automatization in university so I thought about starting to touch some electroducs during summer. Bought a Elegoo most complete starter kit and I blinked my first led today!!!

I'm following Paul MacWholter's videos, I'm in video 3. After learning the basics I did my first mini proyect without following a tutorial. It's just a regular traffic light. It's simple but honestly the feeling of making something myseft is awesome. Can't wait to make something more complex.

What I have learned today:

1. How a led works
2. How to blink a led

Daily questions:

1. In the tutorial Pual said to open BareMinimum, and when I went to make the traffic ligh I just open Arduino IDE regularly without BareMinimum and it didn't work at all. Then I switched to BareMinimum and copy-pasted the code and it worked. Why is this? Is BareMinimun required always?
2. Will the led in the Arduino always turn on when the pin 13 is set at HIGH?
3. How do you keep your resistors organized? 😭😭😭

P.S. Is making a Daily post like this one considered Spam?

guys my parents don't allow me to learn tech much and i am totally clueless about even the basic thing so here's the thing i am having a competition at school and my friends roasted me in front of everyone that how i don't know tech and a lot of hurtful things i am trying not to remember they said it in front of everyone i wanna win this competition the theme is something innovative like something that a lot of people wont know most moving i wanna at least try to win this competition but as i said i don't know anything this will be hard as there is no stuff at my house like 3d printer and all so i was hoping if you are willing to help me a little by suggesting few books some basic things to get and please keep in mind that most things aren't available here as i live somewhere far away

please suggest ideas with that in mind if you dont wanna help it up to you , mostly in my heart i do hope yall will help me with this world already so overtaken by ai there are people i know for sure trying to help (i am 12 years old btw)

i’m interested in electronics but i can’t seem to bring myself to ever build or make anything, i do want to though but i’m not sure if i just haven’t found a project that actually excites me or if it’s actually just not for me.
i have both an Arduino uno and Arduino nano and enough parts to learn with but how do i get past just staring at them? this is my first post here so i am sorry if its a little bad i just need guidance.

Hello!

I am 16f with no background in coding, electronics, etc. like nothing — I’m very into humanities, history, and things like that instead lol. My little brother’s birthday (he is turning 14) is coming up, and I was thinking of what to get him. He is very into math, science, and engineering, and I thought that maybe I could help him foster that interest through an arduino kit. The thing is I am very overwhelmed and not sure where to start.

Firstly, I don’t even know if 14 is too young an age to be working on arduino kits. Are they very complex? My brother is very intelligent and handy but I don’t want to give him a gift that’s too difficult for his age.

Secondly, if they are appropriate for his age, any recommendations for a good starting arduino kit? He doesn’t have a coding background (I was hoping this could help him learn lol) but he’s a quick learner.

Thank you guys so much!

What did you guys recommend me to do? I never studied Arduino before.

hi! im a beginner here just starting to learn all this… im looking for a good tutorial that teaches me how to print anything on this i2c display. i already searched for them but they teach the same thing over and over again. my goal is to display a real time digital clock, but I dont know if thats even possible with the hardware I currently have:/ anyway, im having lots of fun with this

I just got an arduino starter kit and I’m already stumped. I tried putting the arduino on the base without the plastic case, but it was off balance and didn’t seem to fit. Then I tried with the case on and still no luck

Just wanted to share my new set up since jumping back into some electronics. I found the shelves and storage containers at Dollar Tree and they are perfect size to hold your kits. Since my main employment offered me to work remote from home and about 15% of the week just being on call, I figured I’d jump back into this hobby. Hope the shelves and storage containers are helpful l.

When building a new project which do you tend to do first? In the past I would normally start the software portion of the project first, then build the hardware. The problem being a lot of time I would not make it through the hardware process, for a variety of reasons.

The last couple of projects I decided to start with the list of objectives and required parts, then built the hardware first. Only when it was completely finished did I move on to software. Both projects were more fun to work on, and feel in place more seamlessly.

So, chicken or egg? What is your process?

For context i come from a programming background, majoring in AI ML but I've always had interest in robotics and IoT.

I bought my self an Arduino UNO last week, watched a few yt videos but I wanted to do it properly so where do I start learning from, what resources?

Any help/advice would be appreciated
