led strip controller w/ led amp + arduino
Very simple to drive high power LED-
In cases where too many circuits are not needed, peel off with Arduino at a low cost.
The secret is the cheap mini LED amplifier.
This Instructure is about driving the LED bar.
If you would like to see an app, see the instructions below: Arduino Helipad, mini four CopterSee picture for three circuit examples.
The first picture reflects the implementation in this structure.
The Second Circuit is two RGB strips (
Use all 6 PWM outputs on Nano).
The Third Circuit is six monochrome strips (all Nano PWMs).
Up to 12 am ps can be output per Mini LED amplifier.
If you have a good 12 v power supply, you can place more strip you want at the end of a strip ell or strip light.
Each LED \"pixel\" on the strip consists of three LEDs (LED).
Most LED light strips are ordinary anode.
This means that the positive end of the diode is connected at 12 v at both ends of the band.
Connect 12 v to the anode, connect 0 v to B, R, G, light up each circuit.
In the flesh, the monochrome strips and RGB look the same.
Even the monochrome strips have copper connectors marked 12 v, B, R, and G, even if all LEDs are the same color.
The LED amplifier/repeater is sometimes called an RGB amplifier.
Don\'t let that fool you.
They also work for a single color bar.
The LED amplifier is powered by 12 v and the input/output is marked as 12 v, B, R and G, just like a strip.
The integrated use of the device is to obtain the input voltage potential, which can be significantly lower than 12 v at the end of the long band, and lift it back to 12 v by providing more power.
I found that the 5 v voltage difference on the input is enough for the LED amplifier to raise the signal to 12 v on the output, which means that we can switch the amplifier 12 v output through the Arduino digital pin.
The Arduino digital output works at 0 or 5 v.
The circuit connects the 5 v output on the Arduino to the 12 v on the LED amplifier input (common anode).
This looks strange.
I will try to figure it out.
The R, B, and G inputs of the amplifier are connected to the Arduino digital output.
Setting the pin to 0 creates a 5 v potential for the common anode, which will cause the 12 v potential on the corresponding output to light the LED.
In other words, the number 0 turns on the light.
The number 1 turns it off.
Alternatively, when using the PWM duty cycle, 255 is off and 0 is on.
Connect the Arduino to the input and connect the theLED strip to the output of the LED amplifier seen in the picture.
You can go from 5 v or 12 v (
Not some version of Arduino. Check the spec). Your choice.
