Hey all! Just wondering if anyone has had their backorder dispatched yet? I realise they were all supposed to be dealt with in the last couple of weeks but haven’t had any word or dispatch email. My order was in April so is supposed to be on the way by this point?

We talked about this before, and apparently I worked on it.
But I was going through old eagle files and found this. It looks like there is a player 1/2 switch that swaps the RX/TX pins.
It’s also got some RC filters and an audio amp.
It needs to be tested to what happens with the various existing modes of the speaker, but in theory this “should” work just fine. Theoretically the driver wants to have a differential signal, but this will just operate in half cycle so basically the amp is always limited to something like 50% of it’s max output (if driven from a full input). Or so the theory goes…
The software side of it, to avoid blowing anyone’s ears out with serial data… Player 1 sends out a packet on the microphone pin which its then picked up by player 2, and only after that can it send out it’s data on the speaker channel.
Hmm I also realized though that you might still get sound out of the speaker when you have the aux plug connected. Ah nuts the jack needs to pull the other leg of the speaker somehow too. Maybe this is why I stopped working on it…

There is a lot of e-waste on offices. I usually recover stuff just to extract parts, like my famous ball of magnets from dozens of hdds:
Recently there was unnused lcds, so OFC I need more screens, and one just for the arduboy collection

No, I actually genuinely don’t think it should be a Arduboy thing …
Why am I even doing this? I know that my large proto shield is not going to have ICSP access so why am I writing a sketch that depend on physical SPI?
Call me crazy.
I spent hours poking through the ArduboyCore lib (Arduboy1 version) trying to source something useful, only to find it cutting all the corners into one difficult-to-port mess.
I really should try this earlier, but I didn’t. Anyway, it’s now done.
I went to Adafruit’s Github place and downloaded their SSD1306 relevant stuff. Then I poke around their code (it is gigantic, because it is test code and not optimized for size, and it’s readable and very well-documented because it is … well, it’s by Adafruit.)
So I am able to piece together the very bare minimum code that initializes the display and write some data to it (to display).
The sketch (of mine) draw a single clump of pixel (30, 30 to 31, 31) using four drawPixel (most rudimentary method of updating display).
It looked like this:
Not all functions may be available (e.g. EEPROM’s absence from DUE), but this opens up possibility for “compatible” systems that includes the core functions (LED, direction and AB buttons, display).
It would also allow more expandability, such as the massively increased capability for the DUE and the Mega, so the users can develop hardware outside of relevance to Arduboy, only using it as a interface (of graphics and input). Or, if the user wishes, use it to play Arduboy games.
If it garners enough attention I would make a fork of the library and go from there.

So my teacher has given me the task of building a new Arduboy with an Arduino Leonardo, we had a previous one but got new ones that are much better,<There was stuff here but I realised I big stinky and put the converter the wrong way ¯ _(ツ)_/¯ >. My Second problem has an image attached where I upload a piece of code (Mini City for the Arduboy) and the screen flickers weirdly, any help with this? I also had to remove the converter so the display would show

Anyone here has any experience with the Surface Book to help me decide?
I have a Surface Pro 4, and I want to upgrade to one of those…

So I was rewriting some code for an old Arduboy game and I wanted to have the hex values in another file instead of the ino, what format and how would I use that? I’ve tried using .h or .cpp but it rather says ‘no file or directory’ or ‘no scope’. I haven’t read or done much on Arduino yet but wanted to see how to do this.

Hello! I recently tried to buy a retro handheld off of the company’s website, and I was never delivered the product. This has made me untrustworthy of product websites, to say the least. I live in the US. Can anyone else who lives in the US please tell me where they ordered their arduboy from and how long it took to come? If you are willing, please say what region of the US (west coast, east coast, north, ETC) and tell me how long it took to deliver there. Thanks to whoever replies!

Hello arduboy community!!
I have an esp32 Firebeetle with an attachable oled screen that has buttons on it like this https://www.dfrobot.com/product-1744.html
I’d really like to get arduboy going on this bad boy to develop a slightly more powerful tool for interacting with sensors and timers etc around the farm, and play a few games too.
trouble is i cant find much in depth documentation about the process of getting it going, keep in mind that i’m new to C coming from python.
Any help would be amazing including links, advice or anything!!

Hello, I’m new, I’m Belgian and I’m 39,
I love electronics and arduino so I decided to create my arduboy. And I love it :).
Now I have to create games.
Good game everyone

Hi
Thank you for making such a great project possible. And thank you for all the help on the way. I had I lot of fun putting this together and designing the 3D print files for this. Always great to learn something new.
I started last fall, but got a broken screen from Aliexpress. Finally I got a working 1.3" sh1106 screen, and after using Mr. Blinkys great tools, I was finally able to get it working.
The back cover is held on using small hooks and some magnets. It is not as tight as I wanted it, but it stays perfectly in place and does not slide automatically.
I still need to add the RGB led, but I got really tired of soldering And the choice of simple Piezo speakers is probably not the best.
If I were to re-print the shell, I would make more room for a the flat volume potentiometer. And I would make the back cover fit more tightly.
The size of this Arduboy is Depth 14-18mm Width 52mm Height 84mm.

I’ve been thinking this is the best reset button, the only thing I don’t like is that it sticks out on the bottom of the PCB too, wish it wasn’t as tall…

I see that the arduboy seems to be well built? However, just how long lasting are these? Not just the outsides, but the internal electronics too.

Hi All,
I am a C# developer by nature and Arduino/C++ development is new to me. Lots of programming fundamentals seem to carry over like any language, but would like to become more polished.
Any tidbits or knowledge you might be able to transfer would be appreciated. 
I am avidly reading the docs and community to improve myself, but it’s always fun talking with people and getting a code review.
Note: Still working on my development pipeline for making applications on Arduboy. It was mentioned I should have the folder be the same name as the .ino file. If I have a large application I would do this practice so uploading the code is easier with the Arduino IDE.
First Application Code - Updated URL
Bounces text like a screen saver around the screen
Up: Increases Speed
Down:Decreases Speed
A Button: Resets Speed
B Button: Pauses
It was so satisfying getting that stupid text to bounce around the screen.
PS: Anyone using PlatformIO in vs code? Super slick, but still working out making the Serial Monitor to work after uploading code. Seem to say the COM is busy.
Thanks,
– Lincoln

I read in the manual that there is a red light when the arduboy is charging and a yellow light when it has successfully received data. Is there any light signal to show when it is finished charging? If not, I read somewhere that charging electronics overnight could be bad for the battery. Does anyone know a recommended charging time, like 4 hours or something?
TLDR does it have a light signal to tell when it is finished charging, can I charge it overnight, how long should I charge it

I love the NFC technology and have been somewhat active in the Web NFC development.
Has anyone played with NFC and Arduino/Arduboy? This post kinda got me thinking of ways I could combine this with another thing I am passionate about.
I am no where near ready to start modding and barely have any grasp on bread boarding. Would it be possible to use the usb port and connect it to a NFC reader? With some sort of hardware middleware and serial back and forth i’m sure.
Anyway, just feeling it out. Maybe a few of you might have some prior knowledge or at least a place to start.

I need help testing this timelaps.
Please, please, please let me know when you get to the year mark to make sure this code works.
Was getting a little dry and needed a funny.

I’ve made a post before saying that I had an issue uploading a game to my arduboy. Someone responded telling me to download every arduboy library, which I did. My game then uploaded to my arduboy like it was supposed to. However, I decided to upload a different game today and it gave me the same error that I experienced a few days ago. The EXACT same error, despite the fact that I had downloaded every library. There’s now no library that I need to download, yet the game won’t upload to my arduboy. I even checked to make sure my libraries were still downloaded, which they were. I can’t understand what’s happening.

Request:
From 1 to 5, 1 being the worst and 5 being the best, what one word human emotions fit within this range? I’d like to crowd source these for a game i’m working on. If you can think of good increments of emotion feel free to go past this range. I started with a range of 5 so it is easier to start with then start finding emotions between.
I’m working on an emotion spectrum myself, but would be very appreciative on any help.
Example:
Fear, Skeptical, Hope, Content, Joy.
Game:
This isn’t some twisted game, but more trying to foster the want to continue playing and grow the relationship. The more gradual emotions the better the reward as time passes by. With 5 emotions of the entity the time it takes to earn these emotions will take forever. The more emotional spectrum the better.
As time progresses the entity grows to trust you. You can take care of it, but as X time passes without caring for the entity then you lose that trust. If you shut off the game the entity ceases. A morbid game mechanic, but the player has ways of prolonging life by keeping it’s home (Arduboy) charged.
Edit:
Challenge - Take this info graph and try to properly order them. Just curious how others sort this.
