Dear All,
I have been asked to design and build a simple patient call system.
Intended operation.
--------------------------
Switch X is pressed which turns on LED X and a buzzer beeps for 500ms
Circuit description
----------------------
When S X is pressed it supplies power to both LED X and monsotable (M) which triggers a buzzer (B)
There is only one monostable and buzzer for all 3
design questions
----------------------
Which monostable IC should I use if I want to keep the trigger permanantly triggered but rather
activate the monostable with the supply of power to the monostable?
ANY ALTERATIONS OR ALTERNATIVE DESIGNS WOULD BE VERY MUCH APPRECIATED
Thank You
