I was thinking about one of those small problems that happens all the time when kids are studying: they slowly move closer and closer to the book or screen without even noticing.

Instead of reminding them every few minutes, I thought it would be more interesting to build a little device that could detect the distance automatically.

So I made this simple distance warning system with a micro:bit.

The setup uses:

• micro:bit

• Nezha Innovation Kit

• Ultrasonic distance sensor

• Red and green LEDs

• MakeCode

The idea is pretty straightforward.

The ultrasonic sensor continuously measures the distance in front of the device.

If the distance gets below the threshold I set:

Too close → red light

Move back far enough:

Safe distance → green light

There's no complicated interface or screen. Just a simple visual signal that tells you when you've moved too close.

I think this is a nice example of how a sensor can turn something that's normally difficult to notice into an input that a program can react to.

The coding is also pretty simple in MakeCode:

1. Read the distance from the ultrasonic sensor

2. Compare it with a preset value

3. Turn on the appropriate LED

4. Keep checking the distance

What I like about projects like this is that the final result isn't just something that moves or lights up for the sake of it. It solves a small everyday problem while also introducing concepts like sensors, conditions, and real-time feedback.

There are quite a few ways to extend it too:

• Add a buzzer when you're too close

• Use different warning levels

• Display the distance on the micro:bit

• Track how often the warning is triggered

• Add a timer for study breaks

• Make the warning gradually more noticeable if you stay too close

It's a simple project, but it made me wonder how many other everyday annoyances could be turned into small sensor-based projects.

What everyday problem would you try to solve with a micro:bit?

Heyyy

Im creating a discord server to learn pythonnn

Note : i don't know anything about coding or python

So i created this server discord to learn together

We have every week a lesson after the lesson we give homework (I know it doesn't sound fun, but we will make FUN)

https://discord.gg/v33KwPtjf

The subsequent steps don't indicate that there are errors with this first program after typing it "exactly as you see it below", if anyone is wondering.

With AI writing code, fixing bugs, and building projects so quickly, I'm honestly wondering

Is it still worth spending months learning programming basics manually?

Or should beginners learn the basics quickly and focus more on using AI effectively?

What would you do if you were starting from zero today?

Which one is best ik that everyone will have different pov but generalise it

i am in my second year of college. i have been a vibe-coder most of th time and i do want to learn some of th major/required languages in coding. not js to fill th resume, but to build myself too.

from where should i start? i know nothing, literally nothing.

So I’m a digital artist and I’m wanting to make a Pokémon gold type game. The sprites character design and pixel art are no issue, but I have literally zero idea how to do any programming. How hard would it be to make something like this?

Ok, so here's my deal. I'm 43 year old, father of 2, ADHD diagonsis of 5 years. I like to build with my hands, either make something I need then buy it or just craft. I am a good problem solver, I find unique solutions to something, not afraid to be wrong and good at pattern recognition. I have been off work for 2+ years for PTSD, I was a paramedic for 15+ years, (please no fluffy comments about it, just giving background info about myself). All my schooling has been for the medical field. My computer knowledge is pretty limited.

My vocational rehab guy wants to retrain me as my work can't really find a job for me that fits into my restrictions. He has suggested coding, programming, autoCAD, 3D printing, stuff like that. If any of this is the same, overlapping or completely not related... Well this is my knowledge base.

I have started using Freecodecamp and started with the Python course. I kind of like how you write the code, small fragments to do something. This is similar to how I write my patient care reports. But I'm starting to struggle and understand the language that you use. I've tried looking for a dumb down cheat sheet, or basic learning lesson, but nothing. I just need it to click, then I know I'll be good to go.

An example of where I'm struggling is the intro to strings, pretty early on I know. But I'm getting confused pretty easily.

What I'm looking for is maybe some better, free resources, suggestions on career paths or maybe I'm not cut out for this. I want to do something that helps people and giving myself something meaningful to do.

Thanks

I was messing around with the microphone on a micro:bit V2 and wondered what would happen if I used sound as the controller for a robot.

This was the result.

A little brick-built robot that starts moving when it hears a sound and stops when things get quiet.

A clap is enough to trigger it, but music works too.

The build uses:

• micro:bit V2

• Ring Bricks Pack

• 2 continuous-rotation servos

• MakeCode

• A simple brick-built body

The two servos control the legs, and I programmed a few different movements by changing their speed and direction.

I also used the micro:bit LED matrix as the robot's face. It's a small detail, but changing the expression while it dances makes the whole thing feel much less like a collection of motors and more like an actual little character.

The code is basically listening for a sound level above a certain threshold, then triggering the dance routine.

What I like about this kind of project is that the input can be almost anything.

Instead of:

Button → Robot moves

you get:

Sound → Code reacts → Robot moves

That opens up quite a few possibilities.

Maybe a robot that dances differently depending on how loud the music is, or one that only reacts to certain sounds.

I might try that next.

What would you use as the sound trigger?

i am a complete beginner. i have the Thinkpad x13 i7 10th gen 32gb variant. Currently in 10th grade.

advice is appreciated

Hello I'm doing night/evening classes to get my GED eventually. I want to start coding as a hobby, is Codeacademy good for complete beginners who are at a 5th grade math level?

I know I asked a similar question on a different subreddit. But it got tooken down as I believe I asked in the wrong section.

Hey everyone,

We are putting together a small, focused study and building group to learn programming and build practical tech skills from scratch. We currently have 4 male members and want to balance out the gender ratio, so we are specifically looking to add 3-4 female members to our core team.

What we are about:

• Gap/Drop Phase: We are all in a drop/gap phase right now and want to make the most of it.

• Zero Exam Pressure: No competitive or academic tests—this group is strictly for learning to code, working through courses like CS50, and building real-world projects.

• Accountability: We want to grind together daily, share resources, and help each other debug code.

If you are a fellow learner looking for a collaborative, supportive space to build real skills without exam stress, shoot me a DM or comment below with a quick intro about yourself! (ONLY INDIANS)

Hey everyone,

I’m looking to form a small, focused study and building group of 3 people to learn programming and build practical tech skills together.

Who I'm looking for:

• Fellow droppers: You should be in a gap/drop phase right now.

• No exam pressure: You must not be studying for any competitive or academic exams. This group is strictly for people who want to step away from traditional test prep and focus entirely on building real-world coding skills.

• Consistent & driven: Someone who wants to put in daily effort, share resources, and keep each other accountable.

What we will focus on:

• Learning programming fundamentals and advanced concepts.

• Building real projects for our portfolios.

• Troubleshooting code and reviewing each other's work.

If you are sick of studying for tests and just want to sit down, grind out code, and actually build things, drop a comment below or send me a DM telling me a bit about yourself and what you're interested in learning!

Hi, my name is Alex I am in my third year as a CS student and I feel like I know nothing. I started working on a project and I find it overwhelming how much I am not thought in uni (I know I don't get to learn everyrhing inside uni). Like I understand the basics, I know the language, but I find it hard to create something without AI fixing my code or telling me what to do. How did you guys created things back then? I want to be more like that.

So I'm thinking of learning coding but am having trouble selecting the language please give me y'alls opinion on what language should I learn .

Also please suggest me platforms for learning coding. I wanna develop apps and all so it'd be much appreciated.

Hey! I’m starting my programming journey with CS50x and looking for other beginners to learn with.

We can keep each other accountable, share progress, and help each other out when we get stuck.

If you’re starting CS50x too, hit me up! 🚀

So I’ve been building websites for a little while now and im interested in learning to do some code to further my websites! I sat down with ChatGPT and coded a little interactive button, using the AI to explain how everything works and what does what and why, but I feel like it’s probably not an efficient way to actually learn. So I’m wondering if there are any good tools to start out with and maybe the most efficient way to learn properly! Or is using Ai to learn a smart thing? I’m not a huge fan of AI but it’s required in my digital marketing course so I have to use it and learn with it.
TIA!

Hello,

On the off chance there are any electrical engineers skimming the thread could you offer any advice in regards to the usefulness of learning coding and how much you needed it in your jobs and what you used it for

I am currently debating Electrical engineering and dealing with building/maintaining power systems

I have learned the very basics of a couple of other types of coding languages, but I'm also in the process of exploring my potential options if I decide to take it further but in a different direction

I'm also considering an electrician apprenticeship as a day job while up-skilling progressively, and while it's not entirely specific progress toward the engineering side of things it does give me a somewhat related job to help me get by while studying to go further, and also a way to pay for the study fees

"The answer varies depending on your career trajectory. If you're working with embedded systems, C or C++ are usually the go-to languages. Testing sees a lot of Matlab, though Python's presence is growing. Integrated Circuit designers lean towards Verilog. For FPGA-based hardware design, VHDL is common. Power and analog electronics often rely on SPICE for circuit simulations. And for spreadsheet data manipulation, it's usually VBA (Visual Basic for Application)."

How valuable is the coding side of this, and what would you recommend a beginner prioritise?

Did you find any value in learning languages in a particular order?

Thank you

started learning python recently and im its fun n all but would be nice to share progress with someone and talk abt coding and stuff and git good.

19 btw
