Hi All
try to interface the sparkfun uSD data logger to write a once a day file
I have it running and writing but if I remove the card with the power connected
it goes into a hissy fit with both leds flashing alternatively
So I figured why not place a transistor on the V+ as a switch turned on via the picaxes pin so when its
not required to write the card can be removed and the unit does a complete
reset on power up.
can any one recomend a suitable transistor that will not lower the 5v on the power rail to much
as to stop the unit from functioning correctly
as the C33725 I have on hand is reducing the voltage to much for correct usage
