Hi! Working a project where a radio msg from a nRF24L01 will open a relay on a secound arduino with a nRF24L01.
everything works as i want, But i want some better safety feature on the relay.
I have searched and tried to implement a millis.debounce delay, on the incoming data msg but with no luck, seams to only work with a buttonState.
Why i want a timedelay on the receiver is if the nRF24L01 picks up a fast signal from a outside source it wont open the relay. I want it the check if the data msg is constant for about 0.2sec before opening the relay, if it get a signal for less then that it wont open the relay.
I saw that it is possible to have a "data validation" between the two arduino with nRF24L01 and maybe that is the way to go.
See in the code on the Receiver where i want the timedelay.
(im not to good of a programmer i understand some basics)
hope someone can help me with this or guide me in the right direction.
Kind regards// Melker S
