is there an easy way to manually operate a cd tray? Answered
im in the middle of automating my trash can (i know i can just buy one, but what's the fun in that?) and i got the proximity sensor part to work, but i cant think of a way to turn a short burst (in the sensor test circuit i had the led on the output blinked once when my hand got close yay!) into a signal that would power an old cd motor until it opened, pushing the trash can lid open, wait about 10sec or so, then apply reverse polarity for 2sec or so until it closed. i might be able to use a microcontroller to do this, but im just getting into that and i don't want to use one for this unless there isn't another way. if it's relevant im using a 555 to generate a 38khz pulse to an ir led picked up by rpm7138. any ideas?
