Guide for connecting several small RGB 5050 ledstrips?
I tried searching the forums but did not find any description of how to connect a 5050 led strip to an arduino and "Mysensorize" it.
I would like to know how to connect four small 5050 strips to one arduino to be able to control all four led strips individualy.
@Cliff-Karlsson using the search feature and searching for RGB gave me this hit (#8)
looking at the examnples gave this link: https://www.mysensors.org/build/dimmer
You can combine the two of them...
And there is a very recent post https://forum.mysensors.org/topic/4938/rgbw-setup
Yes I have already looked at those links and the first link has an sketch. The second link is for a white-only strip and I guess you have to connect them diferantly to be able to control the colors.
The last link I also looked at but found the pictures pretty hard to follow how all copnnections was made.
Ok, thanks for clearing that up for me. What would the smartest way to connect four induvidally controlable short strips? Can I use one mini pro to control 16 mosfets? (I want to be able to light up four shelves in a bookcase)
@Cliff-Karlsson if you want to dim the strips it requires PWM (pulse width modulation) pens and the nano only has 6 of them (D3, D5, D6, D9, D10 and D11)
D11 and D10 are occupied by the MySensors radio leaving 4 to controll the LED strip.
So you will requires either:
- list itema different Arduino (the MEGA has 15 PWM's)
- or using ShiftPWM (http://www.elcojacobs.com/shiftpwm/)
- or use 4 Arduinos
I am using my RGBW controller like that. I have some of these nodes controlling multiple strips. Although if you want to controll them individually you need a controller for each one. (or build one that has more mosfets, then you are only limited by the number of pwm pins on the arduino you are using).
