...i am mid way through a project...
the petals will be electrically heated so the petal curls, and then the current is switched off so it uncurls (7.5sec to curl, 7.5sec to relax). while the petal does that the LED for that petal will stay shining on it.
so thats my idea. Flexinol is essentially an ohmic resistor and needs 0.4A to curl up in 1 second, so i expect i will need around 0.2A running though the flexinol...
