My project uses a bare bones Atmega328 chip and 4 AA batteries. It needs to spin a stepper motor (sparkfuns 10487 12 v stepper) intermittently.
So I got Pololus item 2117, a step-up converter w 12 V output. I measure 12v with no load, but when I hook it up to M+ on the easy driver board, voltage drops to 10v or less, and the motor wiggles but won't quit spin.
I'd appreciate any advice about how to make this setup work, or about a different setup. Thanks!
