This was my first try developing my own pcb with the toner transfer method. I did this project many years back but it works perfectly to this day.

It filters an audio signal and drives led strips so they pulsate to the beat of a song.

I'm looking for Arduino discussions and there's plenty on Reddit but almost dead silence here.

Is this all there is?

Hello guys! While I am a relatively experienced programmer, I have practically zero experience on the hardware/electronics side of things. I really want and need (I'd like to work in embedded systems) to get this stuff in my "tool belt" of skills, but I am really worried that I will do something wrong or order the wrong parts because it is quite an old project I will be trying to build.

I would like to make this project (EDTracker github) so that i can play all my sim games that benefit from head tracking again. I had one which was pre-built but the connector broke. I would prefer a version with the magnetometer (9150 or 9250). The problem is that due to my inexperience I have no idea where to search for cheap(ish) components, or even if the components listed in the docs are still available or if there are better ones that do the same thing.

I realise this is not much (almost nothing) to go on, but I would really appreciate any help at all th

I have recently started working on my school project which involves writing some c++ for the ESP32. At school everything works fine, but at home only the first time I compile and upload the project (using the Arduino IDE), does it actually work correctly. So the communication is there, it just seems that the first compilation step does something to the program, as every time after that first compilation it refuses to compile. Here are the console outputs of the two compilations:

Hey Made a script to aimbot in aimlab just to challenge myself with learning opencv and color detection. Feel free to use code for your own similar projects!

Working on a joystick. Seems like any protocol I use to read from peripherals is going to be bottlenecked by having just one input. My microcontroller might have multiple ADCs, but there's just one processor stepping through them. Same for spi, or i2c, or uart. There's really only ever one sensor reporting back its data at a time.

I know this might not matter for measurement resolution. Especially if you're polling at like 115k serial or something, but...

That's 8 bits per axis, and three axis. Now that's at least 34 bits. To sample each axis we're down to only 4.5k samples per second. Plus whatever other cycles the controller has to handle... even if I spent half that time doing microcontrolle cycles at like 2k we're probably still well with the best star craft apms or whatever. I'd still like to find some way to really over engineer this thing.

I read a little about tdm, but that's out of my league and I don't kn

This setup allows Arduino to read temperature, control relay based on setpoints, display info on OLED screen, and manage date/time settings with user input through buttons. Adjust based on specific hardware/project requirements.

Designed to replace the faulty electronic control of a blue heat radiator.

I have previously used Arduino Leonardo as it supports the keyboard.h library that enables HID keyboard presses. The latest update of the library is from May 5, 2022. Anyone knows if the Uno rev 4 supports the keyboard library?

Hey all,

I've been sitting on a starter kit for a Mega 2560 R3 board and sensors for over a year. I want to get into it, so bad, but I frankly don't have the time to learn to code this with my job the way it is.

Is there a WYSIWYG program anyone favors, especially for someone new to Linux (I'm using a Raspberry Pi 3 Model B running Raspbian and I have a Raspberry Pi 4 Model B too) and Arduino (board model Mega 2560 R3)?

I found these options. Anyone have experience with them?

I took a WaveShare RP2040-Touch-LCD-1.28and made a program to use it as a touchscreen. This is still very much in the beta phase but the proof of concept works. Here’s my GitHub repo for it.

I’m planning on integrating it into my next split near the thumb cluster.

I know this is MicroPython, but I was having the same issue through Arduino. The IMU on the WaveShare 1.28 module has a fusion engine but I can’t seem to access it via I2C. More detail in the SO post linked.

Modules, chips, and everything in between! What are your favorite sensors?

I did this with a small Arduino uno kit

Seems like a beast to me! I've been thinking of using it for a DIY drums project that needs a lot of analog reads and processing per second.

I've been here for a couple of weeks or so checking things out. So far so good. Since it looks like we're doing this I wanted to say hi to everyone who's migrating or just perusing.

All the Best!

Visiting here from Reddit's r/arduino before the June 12th blackouts. Really liking how Lemmy operates but notice the Arduino community here is less than sparse. Given time, hopefully we can build this community for Arduino enthusiasts who are displeased with Reddit as a platform. I hope to see this place grow over time!

I haven't been a part of the Arduino subreddit for very long - but I've never seen "Africa" performed with stepper motors before! If nothing else, check out the post lower in this community!

While looking into why a stepper motor sometimes makes a sound while stopped, I found.... stepper motor music covers!

If you feel tired about the Arduino IDE and you are fan of terminal. I recommend you to try 'ino' as well as micro as editor.

Ino

Ino is a Python tool to build and upload code to Arduino boards. It is also very lightweight and fully open-source.

1. Install Ino : pip2 install ino
2. Create and initialize the project:

 shell

    
mkdir project
cd project
ino init

  

3. To configure the settings about the board, you can use the following template: name this file ino.ini and add it into the root folder of your project.

 ini

    
[build]
board-model = mega2560

[upload]
board-model = mega2560
serial-port = /dev/ttyACM1

[serial]
serial-port = /dev/ttyACM1


  

4. Code your script by modifying the file src/sketch.ino
5. Build and upload to the Arduino (using the settings of the file ino.ini) run: ìno build && ino upload

Now each time you want to upload the project to the board you just need to run ino buid && ino upload. Ino will use the configuration of ino.ini to build your
