Greetings all!
I have a 2 wire DC motor, my question is, does anyone know how to control it forward and in reverse? Thank you in advance!
You need a bridge driver, see https://www.sparkfun.com/search/results?term=bridge+driver
…the right one to pick depends on how big the motor is and what you’re trying to do with it
Thank you Hugo,
Im trying to make a door lock, to unlock and lock. The lock that i got uses 2x RF remotes, and i want to use my imp ( cause they are way cooler than Rf remote 
)
i got this driver https://www.sparkfun.com/products/9457
and i have this Electronic Door lock http://www.amazon.com/gp/product/B000FBU2KW/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
and the motor is weak, but here similar one https://encrypted-tbn3.gstatic.com/images?q=tbn:ANd9GcTFSBbvBYQeEcAJq6P2CDw69sQSl54JKxCjVF83uLa-TsQoj_UN
Have you considered wiring the imp into the RF remote rather than the lock?
An interesting idea, but i rather eliminate the RF Tx and Rx at all
trying to connect to a rf remote ,i get no luck , im trying to replace a button with transistor, but it doesnt work, any suggestions?
Easiest way is to use a relay to short the button contacts; otherwise, you can use a transistor but you need to see whether the button connects a circuit to power (high side switch) or to ground (low side) and alter your circuit appropriately.
Thank you Hugo, will work on that this weekend
