Arduino vs Raspberry Pi (Part 2)
I've been a bit lax with the blog updating. In Part 1 of this post I promised Part 2 "soon" and here it is, eight weeks later. Oops.
This two-post series, aimed at embedded device beginners, explains some differences between Arduino and Raspberry Pi. In this second part we're going …

If "a poor workman blames his tools" then I am a poor workman when it comes to electronics. Every time I buy new equipment my soldering gets better - nicer soldering stations, different tips, decent magnification. Soldering under a microscope …
