Hello All,
I am trying to make a small DC motor oscillate at a low frequency. I want the motor to travel CW for 2.5 seconds, and then CCW for 2.5 seconds etc. What I've been trying to come up with is a way to wire an H-bridge circuit with a 555 timer as a driver such that the motor switches directions by itself, as long as power is supplied. The main design constraint is size for this project, so I am trying to avoid any larger components (TIP120's are even a concern to give you an idea of the size in question). I have google'd and searched this forum pretty heavily and haven't found quite what I am looking for. Maybe I am searching for the wrong terms?
Any help would be greatly appreciated, and as always, all tips/hints/advice are welcome!
Thank you in advance!
