You need to draw the schematics of your smart interactive automatic toilet freshener. It should clearly show which components are being used and how these are interconnected. There’s no specific format or tool (such as Fritzing, Eagle, KiCad) that you are required to use, as long as the schematics are clear. We do prefer official symbols for common electronic components such as leds, resistors, diodes and the like. Handwritten scans are tolerable but please make sure that they are neat and legible.
