Re: "LeoMorse" Morse Code project for the LeoStick

Andrew Fisher also wrote a little bit of Python as a companion for this... run this on your PC and it pulls tweets down off Twitter, which have any particular hashtag, and passes them through to the serial port for the LeoStick etc. to output them.

Re: Australian version of PowerSwitch Tail

There's a relatively large barrier-to-entry for Freetronics or any other company selling a device like this compared to most other devices, because if it's a fully-assembled ready-to-go device with a 240VAC supply then it needs the appropriate approvals or registrations prior to sale. However it's d...

Re: Embedded 802.11 for microcontroller projects

Because 802.11 is ubiquitous everywhere and everybody uses it, and it's directly connected to the LAN and/or internet. You can use 802.15.4, Zigbee, or other forms of low cost RF communications, in the 2.4 GHz band or in the 434 MHz band or whatever, but then you need an extra block of hardware/firm...

Re: Humidity & Temp Sensor

I highly recommend that your Arduino programs include a little code like the following, during this transition period while v1.0 is still pretty immature. The preprocessor macro tells the sketch what version of the Arduino IDE you're using. #if ARDUINO >= 100 #include "Arduino.h" #else #include "WPr...

Embedded 802.11 for microcontroller projects

There are some existing embedded modules for 802.11 WiFi in embedded devices that you can get relatively easily, like the GainSpain GS1011 module and the Microchip MRF24WB0MA, but you're still looking at about $34-$40 minimum for a basic embedded 802.11 module that you can embed within an Arduino sh...

Re: Arduino article in January 2012 Silicon Chip mag

May I suggest a "base-board" into which one plugs the Mega upside-down? That's actually an idea that I've had in my head for ages but I've never actually gotten around to implementing. There are lots of good ideas and applications where you might want an Arduino "shield" that plugs on top of an Ard...

It actually doesn't matter what programmer you select here, for your purposes, since you're not using an ISP programmer to flash the bootloader on the chip.

Re: Mic Sound Input Module - SPL Conversion

It would be extra awesome if the Freetronics team could open-source a repository for the microphone module on GitHub ;)
