Arduino vs Raspberry Pi (Part 2)

Posted on September 04, 2014

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 …

Arduino vs Raspberry Pi (Part 1)

Posted on June 29, 2014

Decisions, Decisions...

"If I can buy a Raspberry Pi so cheaply, why would I ever use an Arduino for an electronics project?"

I often hear this from people who are new to embedded programming and electronics. This post is the first of two, aimed at beginners in the embedded world …

Flatdrier

Posted on October 01, 2012

Demo page with data from the last week in September

A few months ago, in the dead of Canberra winter, we discovered our flat had a mould problem. Insidious disgusting mould had crept in around our walls. Much scrubbing ensued.

Black mould found behind a cupboard - eww!

We bought a …

Notes on FTDI latency with Arduino

Posted on October 16, 2011

Today I Learned how to minimise latency when sending data to a computer from an Arduino (or any other FTDI-based device.) I learned it specifically for Windows, Linux and OS X.

Well, actually I learned this a few weeks ago while developing the [Hairless MIDI<->Serial Bridge]{style="white-space: nowrap …

Been busy...

Posted on September 24, 2011

Too much going on lately:

  • Canberra Hackerspace still going strong.
  • Road tripping to Newcastle next week with dev_dsp for This Is Not Art. We've signed up to organise an Arduino MIDI controller workshop, and we're giving talks about Hackerspaces and the overlap between fine arts and engineering.
  • I built …

Structured EEPROM access with Arduino/AVRs

Posted on July 01, 2010

On an Arduino or other AVR, EEPROM access is a bit fiddly if you want to store different types of data. In this blog post, I'll show you a quick trick to use when you have lots of structured data to store in EEPROM.

Alternatives

First, the existing alternatives:

  • Arduino …

Servo pulse width range with Arduino

Posted on July 04, 2009

I recently bought a couple of cheap MG996R high-torque servos on ebay, and I want to use them with my Arduino.

Arduino + MG996 + Dusty Breadboard

These have the "JR" servo pinout, so orange = signal, red = V+, brown = V-.

You control these servos by sending a 50Hz pulse width modulated signal. The pulse width determines …
