Hello. Question. I need to do an oscillator for the 9V DC motor. In my case, the motor need to turn clockwise and ccw with a period of +-3 seconds, slowly. What I did is:
555 oscillator. 0V to 10V >> 5V Relay (SPDT) >> H-bridge sourced by 9V.
Now, the problem is that the relay draws at least 10V to start. Even without the motor. It’s logic, not to take another 9V battery. So the question is:
1. Why 10V (15mA)
2. Is there another way to get the automatic motor oscillator.
Thank you.
