Hey guys,
I'm new to the forum, hoping to get a bit of help with a project that I am beginning. I do not have circuit expertise, I took an EE class for non-majors in college that I did not listen to well, so I'm trying to learn a lot now.
What I want to do: The initial goal of my project is to have a sensor detect when an object breaks the IR beam of the sensor. Prior to the beam breaking, I'd like to have an LED string be red, and then after the object breaks the beam have the LED string turn green. I'd be working with an Arduino micro-controller to program the LED string.
Eventual plan: Eventually I'd like to take my initial goal above as a single module, and create multiple modules and tie them all in together. But for right now I'm only focused on the initial goal.
Active IR Sensor (already purchased): Single Beam Photoelectric Detector Active IR Sensor
LED String (planning to buy): ALITOVE 16.4ft WS2812B Individually Addressable LED Strip Light 5050 RGB SMD 150 Pixels Dream Color Waterproof IP66 Black PCB 5V DC
Questions that I have now:
1. Simple question regarding circuit design. I'd like to power this DC project from a wall adapter (only 1 if possible). Both the receiver and the transmitter I am buying each need 12-24V power supply. I'm thinking that I should wire the receiver and transmitter in parallel to leave enough voltage for the LED if I get a 12V or 24V AC/DC power supply. Is this the right thinking? If I try to wire everything in series, I'm thinking that I'd need more than a 24V supply. Anything else to consider?
2. Thinking longer term, if I try to replicate this setup 10 times, and tie them all in together, what would be the most efficient way to connect them, given I don't have 10 wall outlets available?
Thanks in advance,
Nick
