Hey together,
I want to design a modular system with kind of wooden buildings blocks ( 10 x 10 x 10 cm). This blocks shall pass sensor information from one to another in a serial connection. The information finally shall end up in an Arduino/pc.
In this wooden blocks I want to have several inductive proximity sensors to track a metallic object, which will be moving on the wooden surface of the building blocks.
Lets imagine I would put some of the blocks ( like BLOCK A, BLOCK B and BLOCK C ) in a chain and move a metallic stick over it.
Each of the blocks should be able to detect the metallic stick and its position over it. In addition it should be able to forward the tracking data on to the next building block and so on till it sums up in the Arduino/pc.
The blocks shall be connected via magnetic connectors like this one

First of all I would try out this circuit with the Arduino:
https://www.14core.com/wiring-a-metal-detector-sensor-with-npn-proximity-sensor/
Then I would try to get very small sensors, maybe like here
https://www.fargocontrols.com/miniatureinductive.html
I have a good feeling till here, now the questions:
Questions:
- Is there problematic interference with the inductive proximity sensors? I would like to drill holes from underneath of the surface so that the surface itself stays "untouched/neat". I guess 4mm of wood wont effect the magnetic field drastically.
- Would it make sense to have an ADC in every block to avoid interference of analog signals?
- How could the inductive proximity data be transferred from one block to another?
- if the order of the blocks would be changed, how could I get the new order in the block array?
I hope my question are not to unconcrete, if so pls let me know and I´m eager to densify and elaborate!
Best in advance,
Till
