I am working on a project with a reed switch that reads if the door is open and closed.
I have the code running correctly, but tge esp8266 will be running on a 9v battery and I want to minimise the power consumption as much as possible.
I found out aboit deep sleep, and I know that I can wake the esp8266 with the RST.
Here’s the catch.
The reed switch may be 0 or 1 but the rst pin must be pulled to low momentarily.
So how can I make it so if the reed state is changed it will send a pulse of low then HIGH?
I hope you understand my problem, or if there are some alternative approaches would be good.
