Project description
TranslatedAn example of a principled scheme is attached. The example shows 3 sensors and 3 LED tapes. But the fee is needed for the amount that uses all outputs of the Arduino.
Installation of sensors and LED tape to the edge of the board is planned by wire (and not directly on the board), so the contacts for them must be placed on the edge of the board.
This device for contactless lighting in several zones. I would like to know the price and time required to develop a circuit board.
