Hi there everyone im new to the forums and pretty much a beginner in electronics.
My grandfather has gone quite deaf and he lives out in the country on a big property. When someone at the gate rings the doorbell, if he is watching tv in the room he cannot hear it.
I wanted to build a project that can flash an LED or light in the bedroom for 20 seconds or so or until a button is pressed to reset it.
I have recently been learning about pics and I have a PICKIT2 programmer. At first I was thinking of just having a transistor attached to the speaker of the doorbell and the microchip filtering out all the noise of it flickering on and off by having code that just leaves a port high for 20 seconds from the first time it turns on. But then I thought there must be an easier way, my knowledge is very limited when it comes to electronics, a cap and transistor maybe? I wouldnt have a clue on any of the specifications needed.
Secondly once I have integrated it simply to the intercom already being used (without ripping it apart) I was thinking of making it wireless, so I would not have to run 2 wires all the way to the bedroom of their quite large house. I have seen a couple products from microchip but once more I am uncertain of the specs.
I apologize if this is very vague, but I hope I can get some simple yet effective ideas
