I am new to the world of Arduino and am looking to put LED strip lights on my baby stroller (to add visibility at night and cause it's cool!). The programming is not going to be a problem for me, but I have no background in electronics.
I am hoping to use a 5m WS2812B strip with 150 LED's (I likely wont use the entire length but I am not sure how many I will need at this point) and control this with a Arduino Uno r3. What I am struggling with is how to power everything. I have looked at several options including USB power bank usually used for charging cellphones (https://www.amazon.ca/dp/B00P9U9ZXO/_encoding=UTF8?coliid=I1ZGQIFMHA9AUC&colid=2MJJ6QT5E4S3T), a 12v drill battery, or a 11.1v quad chopter battery (https://www.amazon.ca/dp/B004AFHP0Y/_encoding=UTF8?coliid=I2IZ82M6U06AQA&colid=2MJJ6QT5E4S3T).
The USB power banks can only deliver 2.1 amps and I don't think that is going to be enough to drive 150 LED's. I think I am going to need between 7.5 and 9 amps, the reports on how much each LED uses vary. For this example I would use a 5v strip.
For the drill battery I was thinking of taking apart cheap drill (or more likely flashlight that uses a drill battery) and cut off the handle to use that as a mount for the battery. I like this idea but it is the most expensive. I would use a 12v strip for this battery.
I also like the quad chopper battery idea, it is a nice clean package. But I don’t know if the 11.1v is enough to power a 12v strip.
What one of these ideas do you think would work best? Or are there any other ideas that would work better?
Thanks in advance!
