Arduino: Led Strip
- 1 minHello. I have controlled a Led strip with Arduino Uno. You can make it very easily.
- Arduino Uno or any kind of Arduino
- RGB Led Strip (I use 1 m)
- 12V 1A Adapter
- ULN2003A or 3xBD679 NPN or 3xNPN (TIP 120)
- Breadboard with enough jumpers
First you have to buy all these stuff. RGB Led strip has 4 output cables(Red, Green, Blue and 12V Positive).
- With ULN2003A pin 1 is for Digital 9 pin, pin 2 is for Digital 10 pin, and pin 3 is for Digital 11 pin. You have to connect led pins to 16,15,14(R,G,B). Pin 10 is for the Ground.
- With BD679 number 1 is for Arduino with 10K resistor, number 2 is for Led and number 3 goes to ground.
I have made this from ULN2003A and BDN679. This is the code that I used.
