So it has been 4 Years now Bateske and Arduventure KS is an Amazing success, Backer #608 and had to get the plushie. And now I seriously have to build one of these Arduboys myself. Thank you for the inspiration.
Depends. If you are getting a board similar in PIN(like the Arduino Micro) it will work just fine, not to say a board the Arduboy originated from–Arduino Leonardo.
yep. It will no problem for micro and leonardo. But Pro Micro is dirt cheap and can be found easily, I can make a few of arduboy to share for my friends and my kid. I have Arduino Micro in hand but I think it can be use for other project and not thinking about buying it anymore because its a bit expensive and also difficult to find in my country
I’ve done that in my new board package. You can use the features (OLED CS, 2nd speaker pin, green LED with PWM) with a Pro Micro.
Not a problem!
I was still the ONLY guy who knows how to solder (one of my friend once soldered something that later on look like a lump of pig-iron.)
Well most Arduinoare cheap anyway (a micro is about the same price as Micro pro, and sometimes you can get Leonardo for even less. ETH costs, though.)
What does your display look like?
The only four components beside the Arduboy itself-Screen, button, LED, beeper. I got buttons, LED, beeper, adjustable resistors, resistors, and a circuitry board. And some pins.
And if you can kindly direct me to a place that tells me how to wire all of them, that will be very helpful.
And a search of this topic for “leonardo pin” gives one post with most of the information you need.
These are the displays I’m using:
Here’s my wiring table for Arduboy/Arduinos:
As sugested by @MLXXXp have a search for Leonardo pin you will find lot’s of info on wiring up the hardware. Read it care fully.Take a piece of paper and make some notes /make drawings. Figuring out how to and building your own Arduboy is fun and rewarding.
I thought this but then I realised it’s like s gateway drug and leads to more and harder projects.
I know. I’ve ordered parts to make a 100% solderless breadboard Arduboy. Not doing any soldering is quite challeging i think. Will get some of those transparent mini breadboards. Want to hook up a few RGB LEDs to illuminate them
I’ll be using 4 of these transparent mini breadboards and want to light it up more evenly so I probably need more then one RGB LED. Not sure where I’ll be mounting them yet. But I’ll figure it out once I got the parts.
The idea is to put those mini breadboards together in a 2x2 vertical setup so I can put a Arduino micro in the middle of the top two. The 2.4" display will go over the micro with help of some extra pin headers. Bottom two mini breadboards will be mainly used for the buttons.
Hello and welcome to the end! This is the end of the single largest thread of the Arduboy Community!
Welcome to the beginning of the Arduboy Homemade Category!
Please post each new system in it’s own unique thread in the home made category.
(If you have already posted here and would like to make a new thread, that is encouraged! But I’m also looking using the server to create new threads pulling posts out of this one.)
This thread is now closed, happy posting!
This is a great. One thing that comes to mind is something like “NPM” or whatever is used to published Libraries for the Arduino IDE. Ideally, the developer would “publish” via a CLI or web tool of sorts.
::ugh if only i had more time::
If you power such a display or feed its input signals with voltages above the specified maximum ratings, you risk physically damaging the display.
The datasheet for the SSD1306 display chip specifies an absolute maximum supply voltage of 4V and a maximum input voltage of the supply voltage + 0.3V. The recommended maximum supply voltage is 3.3v.
Thank you for the information. It should then be safe if the oled’s supply voltage be fed from the 5v arduino micro/pro micro’s onboard 3.3v regulated output? What about the signal logic lines from the arduino to the oled?
I use the 3.3V output from the Arduino Micro to drive the display on my system. A 5V Sparkfun micro doesn’t have a 3.3V output.
For the signals, I use a level converter module
EDIT, Correction: My display has an on board 3.3V regulator, so I power it with 5V. I use the 3.3V from the Arduino Micro for the low side of the level converter module.
Thank you for the explanation, I understand now. I had thought the pro micro’s vcc pin was the same as the 3.3v regulated output pin of the micro, but you’re right that it isn’t, if powered via USB it will output 5v.
Thank you for taking the time explain it to me.
Where I can purchase a proper display?
