Basic Arduino non-addressable RGB LED Strips configuration making use of TIP120 NPN Darlington resistor
NOTE: Arduino has it's own power suply (different to the LED Strip) and the TIP120 is used to feed in the 12V (2.0A) current into the LED Strip
Wiring Diagram drawn up in Tinkercard
The plug on my LS0964A is aranged as
- +12V
- Blue
- Red
- Green
