Updated code, works a little better.

I'm using a LM7805T with a 4AA battery holder to supply 5V. It's less than ideal because the input voltage is supposed to be >7V (I think), and sometimes I put NiMh batteries in the holder, which give 4X1.2 = 4.8V. So, is there a better way to get 5V consistently from a 4AA format battery...

My project is working, although I'm still tweaking things both in code and electrically. It's a program for PICAXE 08M2 microcontroller to keep blinds open to allow maximum light up to a setpoint. Tweaks the blinds open now and then to try to get more light in, unless the light goes above the...

I'm building a blind controller, based loosely on the circuit at http://www.instructables.com/id/Build-A-Motorized-Window-Blinds-Controller-For-Les/ I couldn't source the relays he specified (DPDT 5.0V Relay, BG Micro # REL1090 $1.19) so bought a few DS4E-S-DC5V instead. They are 5V high...
