I have a device with a magnetic reed switch.
I want to replace the reed switch with something that will close/open the circuit continually, adjustable to anywhere from perhaps once per second to perhaps 4 times per second.
I imagine that the heart of this would be a 555 chip, but that's about all I (think) that I know. I have never constructed anything like this before.
Are there any simple plans anywhere to accomplish something like this?
Thanks,
Randyu
