Introduction To The Arduino Serial Plotter
Version 1.6.6 of the Arduino IDE is upon us, and with it – among other novelties – is the Serial Plotter, a basic graphing utility for visualizing data, debugging and show-off. What is it, and how to use it? Here’s a little guide…
Getting an ATtiny85 to Transmit Over Serial
How Arduino’s Serial transmissions are constructed, and a basic demonstration of the ATtiny85 sending Serial-like messages using an internal timer and some basic bit manipulation.

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!
Programming AVR Microcontrollers With Linux (The Relatively Easy Way)
After playing with the Arduino for a certain period, you may feel an urge to move forward to stand-alone microcontrollers. The official way to program AVR MCUs is with the Atmel Studio IDE and an Atmel programmer/debugger, such as Atmel-ICE. But Atmel Studio is only for Windows, and the programmers are pretty expensive. Here’s an alternative.

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.
