/diy/ - Do It Yourself

So for a long LED run (15m) I know power needs to be re-injected about every 5m, but would the ground and data input lines be fine?

Trying to figure out if I need single or tri-core wire.

Also for 3 x 5m strips of 5v could I re-inject power from 1 5v 5amp psu?

Not seeing a Raspberry Pi General thread today, so I'll start.

Anybody had an experience with using Bluetooth on an RPi? What I want to do is make the RPi a Bluetooth device that I can connect to with my phone, and control the GPIO pins from my phone. Can the RPi be configured as a Bluetooth device like this, or is it only a host? Do I need to buy in to some other Bluetooth system instead?

If it would work, any advice on writing a quick and dirty android app for the phone to create buttons that activate the GPIO pins?

Alright /diy/ I just bought an arduino starter kit, Uno R3 2.8 touchscreen with sd card for arduino board module and the elagoo 37 in 1 sensor module kit for arduino uno r3 what should i do now? I'm kinda new, did robotics a bit before in highschool. what are the different projects i can work on with this?

Hello /diy/,

Anybody know a good method for sending messages wirelessly to an Arduino? I want to setup independent self-powered units that send sensory information that the Arduino can pick up. The less noise the better.

Summer holidays be here, doing advanced higher engineering at school, got homework to learn the programming language for Arduino, haven't started yet, 3 weeks left of holiday, currently also learning R for bioinformatics research project on anxiety I'm currently doing 8-5, Monday-Friday every week. How fucked am I?? Also how good is Arduino in general? I'm going to be using it for my 60% of final grade project: designing and creating a scale prototype for a 24hr lighting system running on renewable energy which must be able to function even when no direct source of energy is available. If anyone is curious here is my project proposal:
For my advanced higher engineering project I will be creating a 24 hour lighting system which runs on renewable energy and rechargeable batteries so that the system can continue to operate even when no direct source of energy is available.

The project shall require a vast knowledge of engineering ranging from applied electronics in the wiring and composition of the components to structural engineering ensuring a stable, safe base for the system.

The project shall also require relevant research into the functions of wind turbines and their relative power input as well as the functioning and workings of rechargeable batteries ensuring an efficient circuit and therefore system.

As challenging as the project is, I am sure it will be completed within the given timeframe. I have already gained numerous key skills within the areas that will be required to undertake the project from my previous studies. I have also already conducted preliminary research and now have an idea of the magnitude of the project and understand vaguely the time required to complete it.

What low-cost embedded platforms allow setting breakpoints while debugging?

I know Arduino doesn't.

Does anyone know of any interesting Arduino projects, I'm currently learning how to use this thing and need some inspiration for my own project.

So I've been working on an Arduino project for a little bit and it's not terribly complex, so I'm just about finished with it

That being said, how do I turn that into that prototype into a more usable object? With the breadboard and the Uno, it's not that great for what I want to do with it. Basically I just need to use a pot to control the angle of a servo, and I'd like the servo to be a decent length away from the pot (like, 2-3 feet)

How do I take my Arduino prototype and turn it into an actual product?
