I have a project utilising MQ-2 gas sensor, DHT-22,RTC and a 12864 LCD. Connecting all of this to arduino powered from a usb source shows that the lcd doesn't get enough power. I would like my final assembly on arduino nano powered by a 1A micro usb charger from an android phone. So should i in some way split the power line before it enters arduino and power LCD in parallel? If the answer is yes - what is the best way to split? Cut the micro usb cable from the socket?
Powered USB hub might be easier.
Powered usb hub wil either
- Bring power to arduino and i will have the same problems
- 2 cable to run which is just too much.
So generally speaking i am loomking for a 1 power socket | 1 cable running solution
