5vdc/670mA max miniature gear motor (load is such that current will be far
below 670). I want to set speed with pot control and leave it (may replace
pot with fixed R when best speed is discovered). Forward only, no reverse.
Just need single transistor, if possible, to do the work. Will use wall wart
p.s. for power.
Speed accuracy, etc. not necessary. This is for friend's art exhibit.
Google turns up an extraordinary number of patents, data sheets for quite
bright ideas using controller ICs, H-bridges, digital controls with feedback,
etc. Much more than I'm looking for.
Your ideas or pointers to designs greatly appreciated.
Thanks,
