Awesome Little Wolf In Sheep's Clothing: Looks Like A NE555 Timer But Is A Full-Fledged Microcontroller

Some tasks are too complex to be implemented solely with discrete components but not really computing-intensive: an emergency light needs to flash a LED with a given light pattern, or sensor data needs to be read and written to SD Card, or based on some input, different outputs need to be controlled - you get the idea.

The ATTiny family of microcontrollers is perfect for this. They are small (come in standard DIP housings), provide GPIOs and can do most of what their bigger brothers can do to - just not so fast, and with (much) less available memory.

*ATTiny are so tiny they don’t come with USB-to-Serial functionality or any other means of connecting them to a PC. In order to upload firmware, you need to plug them into a programmer. That’s a board with the missing USB functionality.


Please do leave comments below. I am using utteran.ce, an open-source and ad-free light-weight commenting system.

Here is how your comments are stored

Whenever you leave a comment, a new github issue is created on your behalf.

  • All comments become trackable issues in the Github Issues section, and I (and you) can follow up on them.

  • There is no third-party provider, no disrupting ads, and everything remains transparent inside github.

Github Users Yes, Spammers No

To keep spammers out and comments attributable, all you do is log in using your (free) github account and grant the permission to submit issues on your behalf.

If you don’t have a github account yet, go get yourself one - it’s free and simple.

If for any reason you do not feel comfortable with letting the commenting system submit issues for you, then visit Github Issues directly, i.e. by clicking the red button Submit Issue at the bottom of each page, and submit your issue manually. You control everything.


For chit-chat and quick questions, feel free to visit and participate in Discussions. They work much like classic forums or bulletin boards. Just keep in mind: your valued input isn’t equally well trackable there.
