Quick LED Strip question...
greetings! i've got ~4m of rgb led strips in project (in short, arduino listens messages on serial , enables/disables various channel outputs (3 wires per channel) via mosfets. first off, 12v/15w psu connected arduino's gnd , fading via pwm works on of strips in each channel. it's working fine (as need to, anyway) when 3 of total 4 channels in use. each channel functions should when activated independently (shelf shelf), positive not wiring/connectivity issue. when activate 4th channel strips on, entire system goes spastic , of strips blink intermittently; drop using 3 of 4 channels, works fine. think issue due insufficient power, wanted run topical subject before go scrambling info of components in use... thoughts?
4 meters of rgb strip , 15w power supply might not enough. if power supply getting hot 3 channels ?
how arduino board powered ?
can use usb power arduino (or seperate power supply) , rgb strips 12v power supply. use multimeter measure voltages , current.
