Do you need a cheap , tiny PIC Microcontroller Development  board witch 
you can place in your walled ?
PicDevUSB is for you. It costs only £7 ( for first 100 kickstarter 
backers).
What can it do? All kinds of stuff!
You basically get a micro controller and a lot of inputs / outputs. ( 
I/O, PWM, UART, SPI, I2C, ADC, USB etc )
It can be programmed directly via on board USB connecter
The interactive course included within the "Learning Kit" (£49 for first 
100 kickstarter backers) has all for PIC Microcontroller Education 
course.
From Basic Blinking LED to Traffic Light Control, Robotic voice 
generation, Game Using Color LCD, Remote controlling Devices via PC, IR 
and mobile phone.
I’m a big fan of PIC Microcontoller development board like this. For 
arduino you find a lots but for PIC they are very few.it’s a pretty 
impressive feat. They’ve already gone way over their goal and they’ll be 
shipping in July.
