I just ran across an even cheaper way to add WiFi to a microcontroller project: the ESP8266 SoC, which is a $5 serial-to-WiFi module with an AT command set and onboard TCP/IP, sort of like the WizNet ethernet modules that they put on Arduino Ethernet shields. The supplier's page is here: https://espressif.com/en/products/esp8266/ Apparently it's a Chinese part with poor documentation and is not bug-free, but as it's got a small 32 bit microcontroller onboard that you can put code on, it could potentially be a one-chip solution for projects with low computation needs, and community support appears to be growing for it. Someone has even created firmware for it that integrates Lua and a node-style API: https://github.com/nodemcu/nodemcu-firmware At the $5 price point, you could have a *lot* of wireless sensors around your house. :) --Levi /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
