The ESP8266 (AKA Wi07C) is a cheap (less than $10), tiny WiFi module that can be hooked up to any micro-controller that can feed it Serial (UART) commands. You can use this module to send data to or receive data from web sites. This puppy is cheap, but capable!
Currently (as of Nov 15, 2014), there are at least 3 versions of the ESP8266 being sold. The hardware wiki at ESP8266-Wiki has details. I got mine from adafruit. Why? Adafruit offers a curated collection of products. They’re either superior products designed by ladyada herself, or vetted outside products that are the current best available. So, I knew I was getting latest model of the ESP8266 which allows modifying the baud rate. When I got my modules from adafruit, the packing bag was labelled “fw 0.9.2.2″. Good to know. (read more)

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
