How to drive latching relais ?
retrolefty:
That's what I did on a project I made using a 5v low current single coil latching relay by just driving them directly from two digital output pins from an avr328 mc. I worried a little about reverse coil collapsing current spikes but didn't seem to cause any problems even after several years. Still probably not a recommended best practice method but it worked for me and my application.
