Hi all!
I am relatively new in electronics so I appreciate any helps from you all!
I will try my best to explain my design, please pardon me if there are a lot of error in it.
Overall, I am trying to design : An infrared sensor when detected something , will go through a comparator LM393, then its output to the input of 74HC04 HEX inverter IC. And in turn drive a motor.
I have grounded all the unused input of 74hc04.
It is a 5Vdc relay and 5v DC motor.
My problem is upon connecting to 6v power supply, it works. However when I supply it with a 9V battery that goes through LM7806 voltage regulator. The relay made that fast switching noise continuously and the motor wouldn't start.
What have I done wrong?? Been trying to figure it out for the last two days..
Thanks again in advance to all who reply!
