World Domination Using Arduinos and Websockets

I've done a lot of microchip pic programming but for equally simple(read beginners) and cheaper avr development I would recommend a teensy. Besides using a standard pinout spacing you can also program it with the arduino ide if you feel so inclined. Of course if you want to use the arduino shields, it's more convoluted, but if you just want to light a few leds, read some sensors, it should be enough.

Anyway, it's quite nice to have all these possibilities; some years ago the barrier to entry was much higher, now with 10 minutes of tutorial reading you can light a led or control a servo through your browser from the other side of the world, which is fantastic.

The spacing of the Arduino pins (between 7 and 8) is a strange decision. But a big advantage of the Arduino is it's popularity. There are a lot of Arduino shields on the market.

The grblShield for example (https://www.synthetos.com/webstore/index.php/assembled-elect...). You just put it on top of your Arduino and you have a nice CNC setup.

But I'll keep an eye on the Teensy. Never heard of it, but it is looking nice!

Another great thing about the Teensy++ is that it has a AT90USB1286 which offers 128 KB of flash and 8 KB of RAM. That is a big improvement over the Arduino Uno's ATmega328 that offers 32 KB of flash and 2 KB of RAM.

This is one of the two things that got me to order one last night. Being able to build with it on a breadboard makes a huge difference compared to the arduino. I've got a number of fun projects to do that the breadboard makes more fun to start. (Particularly things with model trains and monitoring window sensors).

Can you do Socket programming on a PIC?

Sure, http://www.sics.se/~adam/lwip/ has a BSD socket API.

Nice, it'd be fun to try hooking up a PIC controller to a Websocket. Maybe I'll try that next!
