Hello everyone, well my current project requires me to create a circuit with 12 Total LEDs (4 red, 4 green and 4 yellow).
The whole idea is to simulate a 4-way traffic light stop basically, 2 sides opposed to each other.
In the image i have attached to the post i have used 220ohms resistors.
What the final result that I am trying to achieve is to have left side Red LEDs light up, with right side green LEDs on, etc.
My questions are this:
- will the Arduino be able to power 2 LEDs from a single Pin like in my simulation with 220omhs on each LED?
- will there be enough power for the 4 Motion Detection Units Plus the LEDs, or should I power the unis from another source, etc?
