Utilizing only the cheap components required for regular sensor functionality, this ATtiny212-based design adds two-way wireless communication for tweaking and reporting of its own parameters. Here’s how it came to be.

0.000011574Hz
What is the lowest possible clock frequency at which a microcontroller can still do useful work? Here’s a little project that attempts to explore this weird question.
How I Misunderstood and Improved the MagSpoof
The story of a silly misunderstanding, by way of which I significantly improved the efficiency of the MagSpoof (Samy Kamkar‘s famous project).

595 Continued: A More Advanced Example
I finished the 595 Beginner’s Guide with a fairly simple example project. As a supplement, here’s another project, based on the same setup but just a little bit more complex, where we manipulate another input pin on the IC – and by doing that, control the output LED brightness!
Beginner’s Guide To The 595 Shift Register
In this guide I will introduce the cheap and useful IC (Integrated Circuit) nicknamed “595” – a Serial-to-Parallel chip, which is commonly used as an output port expander for Arduino and other MCU projects.
