Arduino Training Course – Saturday 29th


Please note that we moved the Advanced Course to this Saturday – last week was a bit of mare 🙂  The Stats 4 Hackers will be next Saturday (sorry for the inconvenience).

On Saturday, we will be dealing with the
1. ATTiny – cheap Arduino compatible chip – costs R30 – why commit your R270 Arduino to a project, most cases you only need the Tiny.  It uses the same code and IDE as the Arduino, so the learning curve is quite friendly.
2. I2C / TWI – a protocol for hooking together Arduino’s, Tiny’s and other devices like Nintendo Nunchuck controller (  Great for using ATtiny’s as sensors that pushes data to a central Arduino that sends out control signals
3. SD Card – very handy for sensor readings, energy logger, DSC traffic 🙂  Reading and writing to an SD card is very easy and you could use this with your energy logger, to record minute data and analyse later.

As usual we will start at 9 and run to 13.  We will supply all the hardware etc.

What you need to bring is your Arduino, laptop, breadboard etc.  If you want to attend but don’t have any of these, please indicate in your mail that you need it.

The cost is R300 if you bring your own micro SD card, otherwise we will pick these up (about R100 from Incredible Connection for 2GB – maybe cheaper, so shop around) – again please indicate if you need one.  You will probably wipe the contents of the card, so please backup any data that you don’t want to loose.

Please mail me at schalk dot heunis at gmail dot com, if you want to attend.

Energy Logger Resources


Very exited. Today is the Arduino Energy Logger Build day. Here is a basic presentation for the day. Over time I will add to this page and create more links and resources similar to the Arduino Basic Course Day.

H4H on Let’s Talk Geek


Gerrit got H4H onto Lets Talk Geek, a locally produced Vod/Podcast.  Check out  Lets Talk Geek 67

Looking at this now, I was fairly nervous – but it was really quite an experience 🙂  Once I started talking, I relaxed and gave a run down of the house, training and our projects.  The H4H bits start around 17:55
