Below is the drawing of a block diagram of my final project ( a standalone alarm).Fuctionality of the alarm system: Once the motion sensor detects a signal is fed into the processor which process it and power a speaker and generate a siren tone similar to the police siren.
Below is the rendering of the above block diagram.I learn rendering as explained above
Here is the design of my final project ( Stand alone alarm).The discase below will house what is in the block diagram above, those are electronics components which i anticipate to fabricate later in the cause of the semester.
Find below the first design of my project,a standalone alarm.
The second design of the project with an opening and its cover.The CAD file is downable below, just below the design at the corner.
