I wanted to make a pressure sensor matt to detect intruders in a few different places in my lands. I found this article.
This circuit uses a 16 channel multiplexer for each rows and columns that's great I like it. I was wondering does anyone know how to do this with way way more rows and columns. This looks like it could get really complicated. I was thinking about making a really large area so I came up with this. How about using the rx tx on the Arduino. What component can generate a number based on which row column is pressed then send it to the rx tx. I could even use a different resistor for each row or column, then use an Arduino volt meter to read the amount of power and that could tell me what row or column is pressed? Any ideas on how to make this less complicated and without having to buy tones of arduino's? Cant wait to hear the tips.
