i want to make a doorbell , after pressing 3 time or 5sec after without responce, another recorder circuit will work for record the visitor voice.... so how can i mix up the circuit, is the sensor needed???
You need to inform the visitor that there's a voice recorder activated to record the information. So after particular no./sec of attempt failed, turn on this information playback for eg,
*) "Hey dude, voice recorder is activated, please inform your message loudly to me."
*) "Press the red button to record a voice message that'll be played back once the house owner opens the door."
Sounds interesting project to me
PS: Integrate with a clock so that the house owner can check the time and voice message of each visitors -like missed call alerts in mobile phones. It's gonna be a great project.
u need a voice recorder with micro controller coz mc will only pass the info to the rec ic saying that 3 attempts have been done and to begin voice recording....
i need some time to study on this i ll ask one of my friend and let you know...
Best to forget if you don't intend to use a micro in this project. Using a micro I feel this project will be a fun and learning for you and you may ask for coding help in the microcontrollers section. The complication depends on your dedication, and I'm sure you'll be a PIC expert after doing this project
hahaha , i wish to learn the PIC , but no teacher teach me XD and i m taking E&E , if my project is more base on programming , my lecturer wont approve my project
