JTAG mkII with atmega168
Two things! 1) The JTAG mkII's 10 pin connector is different than the 10 pin connector on the STK500. 2) To start debugging the mkII needs to enable debug wire mode on the 168...

Two power supplies
Um... Why not put the regulator on the +6volts in to generate +5volts out. Then use a diode switch (two 1n5817s) to switch between the 4.5 volt from the battery and the +5volt...

PID trouble
Problems I see are. // the derivative is the difference between the error // for the current pass and the previous pass deriv = this_error - last_error; You need to filter...
