How to build a timer for controlling the auger on a pellet stove?
Yep.  I think you will definitely want pots* to tweak your PID loop gains.  They're cheap, and a lot handier than constantly going back to the programmer and tinkering...

Chip Suggestion for Square Wave Generation
Indeed.  It is an "Olimex" board, but did they install those components?  Who knows?  Still, as jgm pointed out, this is wildly OT, so I'm shutting up on this one...
