Hello everyone,
I have a circuit regulated with a LDO 9VDC that uses a 555 timer and I want it to work when I activate the circuit with a magnet. Willing to do that I chose a reed switch and as I could read, most reed switches have a NO contact.
That said, the normal application would make the 555 work when you approach a magnet to the switch and the contact is closed; but I want to reverse it, I want to make the 555 timer work when the magnet is far from the swtich and stop working when the magnet gets close and the switch closes.
What do you think is the most efficient way to do this? I want to use a NO switch, so using a NC switch is not an option.
