Why not control it with a MOSFET to begin with? I've done this, worked ok. In my case the project started life as a completely analog (software not permitted) solution to cycling a linear actuator to one of three positions every time it was powered up. Used a (slightly) under rated dual-coil latching relay as both a non-volatile memory bit and the steering logic to control motor direction - but it did not open or close under load. After a few years and a hundred or so units in the field, I finally convinced them to let me throw a PIC at it. Mostly because the no-software adjustment process involved adjusting five trimpots and that was more than users could repeatably manage. -Denny --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
