Hello, I'm starting to learn about arduino and electronics, if you could help me please.
I want to use the motion detector VD01Y-A3 to connect it to Arduino, to activate some things when it detects movement.
The detector comes to connect it to a led strip directly and that with the movement activates the led strip.
But I want to use it as an input of my arduino.
What do you think is the right way to connect it?
It's pretty easy, it has only V+ V- and LED + LED-.
My question if I connect the LED + to the digital input of the arduino, should I connect the negative to GND directly? Do you think it is necessary to put some kind of resistor somewhere?
Thank you very much for your help.
