Good Morning All
I have made a basic nrf2rl01 temperature alarm with master and 2 slaves .
The slaves monitor the return temperature in 2 seperate heating systems if the temperature falls below a set temperature a LED turns on indicating a fault if i add a sounder how could i turn the souder off without turning the LED off ,i only want the led to go off when the heating fault is cleared ie reset boier or pump in plant room
I have managed to use diodes and latching a relay to turn of the alarm i push a button switch latches the relay and breaks the 5volts to the souder.
Sorry for the long description i am not very good at creating a short topic to get my question across
Thanks oldguyjn
Put the sounder on its own pin and add a button to silence the sounder when it is pressed
Put the buzzer on a different digital output.
Let the appereance (so if a change of alarmFlag from false to true is detected) of an alarm take the output high.
Add a buzzer reset button to make everything quiet.

)
But, that is what diagrams, links, and schematics are perfect for.
Too bad, I was about to apply
