I have purchased a rain drop sensor. it is actually a 5v potentio meter.. I need to get a dc motor running when it detects a rain drop. the speed of the motor should increase as rain increases. Can any body suggest a board and program. i am completely new to this electronics. [rain sensor.jpg]

Suggest a suitable board for rain drop sensor.
