So, what can you do with Attiny’s 5 i/o pins?
UPDATE: New game, “UFO Escape” side scroller
I saw this great Attiny OLED project on http://tinusaur.wordpress.com/ and decided to try out the screen (It will be very handy as a mode display for a remote for my http://orb.photo/ project)
So I set out to make myself familiar with the screen and make something fun in the process. I made a remix of the classic breakout game, here is a video of the gameplay:
Parts required:
- Attiny85 + dip8 socket
- SSD1306 OLED screen
- 2x push buttons
- 2x resistors (10kOhm optimal)
- 3x4cm copper clad board
- Piezo speaker
- 3V 2032 coin cell battery
- Paper clip
So first of all you want to create the PCB, to do this just design the layout (printable pcb pdf)
Print the design on a page from a glossy magazine with a laser printer and use an iron or a laminator to transfer the design to the copper. Put the PCB into ferric chloride until the copper is etched away
Clean off the toner with acetone:
Drill the holes and solder the parts. The speaker is soldered to PB1 pin on the attiny and ground. Connect the large ground pads with a bit of wire. Bend and solder the paper clip to keep the battery in place.
3D print the case from Thingiverse
Program the attiny85 with the code and enjoy:

Which library is included before font6x8.h ?
Sorry, just seen this, its the eeprom library, must’ve been stripped out as a tag because of <>
I’m having trouble compiling this. I keep getting ” ‘ssd1306_xxx’ was not declared in this scope” for all the ssd1306_ commands. I notice that one of the #include is blank up there in your code–which library is supposed to be there? I tried #include but got the same problems. When you have a moment, can you clear up that part of your code? Thank you for this fun project!

Thank you for your quick reply! I’m still getting the errors, but I’m trying to figure it out from the tinusaur guide there. We should #include the ssd1306xled libraries too, right? I tried adding ssd1306xled8x16.h and ssd1306xled.h but still have the same problems. Maybe I didn’t put them in the right directory?
Thanks again 🙂
I find that I can generally find a solution on google by searching for the error message you get from the compiler. Another thing to check is that you have the attiny85 board selected as it will not compile under a different board. I can email you my libraries and hardware folders if you want, email me at [email protected]
please “my libraries and hardware folders” [email protected] thank you
Please download from here: https://drive.google.com/file/d/0B3bO_ZNaxxnlUGt5MnBjeEdnLU0/view?usp=sharing&resourcekey=0-w979b4pXWmMLka7_f0kU5w
I’m a newbe and I’m having trouble getting the sketch to
compile. also don’t know if the board choice is correct.
I’ve used attiny85’s on a couple of simple led dice projects and I don’t know how to code unfortunately. also can you send me your library and hardware files?
Any help would be greatly appreciated.
These are the errors I’m getting:

Is it pissible to use a nokia 5110 lcd display insted of SSD1306 OLED screen.
Hi, I’m not sure, you will have to look up the specs for the screen and adopt the code.
i don’t really know as well, but i guess if you want to use a 5110 display, then you should switch to a more powerful uController, i guess a AtMega328 would do perfect for that.
Hope i could help 🙂
Why is the game running so slow???
Make sure you use the 8 mhz bootloader on the Attiny85
I would be interested in getting one of your kits if you make them available. Nice job!
Hi Dylan, I don’t currently have any kits available unfortunately. I’m hoping to make a larger batch at some point, meanwhile you can make one using the files and instructions provided.
Hi Ilya, congratulations! It is a outstanding project.
I have almost same OLED display, but doesn’t have I2C communication, it uses SPI (four communications pins, plus clearscreen and VCC/GND pins).
My question: there is some easy form to convert the communication sections from your code to adapt to SPI display?
Once more, congratulations!
Thank you Jaldomir, unfortunately there are not enough pins on the attiny85 for the SPI screen + 2 buttons + speaker so there is not an east fix. You could look up reference sheet for your screen and use a microcontroller with more pins but you would have to modify the code
Excellent work ilya 🙂
I’m trying to print the pcb from your pdf, but the results aren’t good. My laser printer on Xubuntu print the blak traces in gray, so use the print for toner transfer is almost impossible. Can you provide the kicad files? From Kikad I can print the pcbs in solid black, maybe the cause is the printer driver..
Thanks a lot, Mirko 🙂
Hi Mirko, the board was created in a different tool (pcb creator), you should be able to change the print settings via the printer driver. Make sure to turn off any toner saving options.
Thanks, it was the printer’s driver (sorry Samsung, I’m not so ECO, lol).
Now I must how to fix the infamous library error:
“ssd1306_char_f6x8′ was not declared in this scope”
Hi, could you please send me the HEX file with the code and programming fuses? I can not make it out of the text … Thank Radek
hello Ilya,
I,ve tried to download a couple of your sketches using the attiny85 as a pocket game. I think they’re very cool.
First of all I’m not a programmer( I wish), I’m a 69 year tinkerer and love to make things. Anyway I need your help if you don’t mind. here’s the error report for the above sketch. I have installed all the libraries needed.
This report would have more information with

enabled in File > Preferences.

Hi Ron, sorry about the delay, it looks like you are missing the library for controlling the screen.
There are my library folders for use with Arduino 1.0 you can find here: https://drive.google.com/file/d/0B3bO_ZNaxxnlUGt5MnBjeEdnLU0/view?usp=sharing&resourcekey=0-w979b4pXWmMLka7_f0kU5w
I tried for several days, I am a newb when it comes to programming but I was still able to do most builds through instructions, but this time I am failing and failing and seem that I cant find the right libraries for arduino IDE I really wanted to make this so hard but I give up I am so frustrated right now I cant even describe, I printed the case did everything but I am to dumb to do it.
Here is a link to a working arduino with all the libs and hardware folders: https://drive.google.com/open?id=0B3bO_ZNaxxnld3F5X3VpNUlNM0E
Hi ilya,
do I need run arduino 1.0 ide to make this work?
I run 1.8 and I get the sketch to compile and download, but nothing works/shows on the screen???
all connections have been verified many times per your schematic drwg.
please advise, much thanks.
