Hello there ,
i'm currently working on a project with an arduino nano, the components that i will be using are :
- 1 Arduino nano
- WS2812B-8 ( 8 LED addressable strip ),
- 5v water pump ( model : jt-dc3w-3 ),
- LCD Display IIC I2C TWI,
- 1 relay module,
- 1 3.3v moisture sensor.
Beeing the first project that i'm working on i can't really tell how to power it all up.
I've tried powering LCD, pump, relay from 5v pin, but noticed whenever the pump was running, the backlight of the LCD display went almost null... i suggest it's due to voltage drop (?).
Can i use a 5v 2A adapter to power externally the arduino (Vin port) ,the pump and all other components?
Thanks a lot!
