I am doing a project on an Arduino Uno, connecting a 15.4 ft. RGB LED Strip. (Specifically this onehttp://www.amazon.com/gp/product/B007X968RA/ref=oh_details_o00_s00_i00
Powering the Arduino, I have a 12 V/ 3A power converter that came with the LED's (so it has to work, right
Vin = 12 V of LED Strip
PWM #9: Blue LED's
PWM #10 Red LED's
PWM #11 Green LED's
However, my problem is that when everything is connected, the Red LED's are always slightly on, no matter where plugged into.. However, they do not do this when plugged into the power supply that came with LED's, only when plugged into the board.
Also, everything also sees a bit dim. If i run a wire from the "green" led connection to the GND, it get's the normal brightness.
Any idea how to fix this??
I appreciate all help...
PS: I know that the LED strips with the 2801 are a lot easier, but I want to get this to work first. Again, thanks for all help
