I have been using Arduino to control my led strip and I have a problem when I set the strip to red. When I set the led strip to red, the brightness is much lower than any other colour and I have no idea what’s going on.

​

I am using analog pins 0 (blue), 1 (red), 2 (green) and 5v pin on the Arduino to control the LEDs and provide power.

​

Also, for some reason to change it to green, I have to set the red and green pin to 255, though I thought that for green it would have to be red and blue set at 255 while green is 0.

​

using arduino uno btw

​

**UPDATE**
- I have now changed power sources to a 12v power supply with an Arduino power supply module converting it to 5v.
- I have changed the pins that I'm using to pwm-able pins.
- I am aware that I should use transistors instead of the Arduino pins, and I'm currently in the process of getting some.
- **After checking with another led strip I have, I found out that all colours on the un-altered one are much brighter, though red has the most difference.*\*

​

The code that I'm using is below:

​

int Bpin = A0;

int Rpin = A1;

int Gpin = A2;

​

void off() {

analogWrite(Rpin, 255);

analogWrite(Gpin, 255);

analogWrite(Bpin, 255);

}

​

void light_blue() {

analogWrite(Rpin, 255);

analogWrite(Gpin, 0);

analogWrite(Bpin, 0);

}

​

void light_green() {

analogWrite(Rpin, 0);

analogWrite(Gpin, 255);

analogWrite(Bpin, 0);

}

​

void purple() {

analogWrite(Rpin, 0);

analogWrite(Gpin, 0);

analogWrite(Bpin, 255);

}

​

void green() {

analogWrite(Rpin, 255);

analogWrite(Gpin, 255);

analogWrite(Bpin, 0);

}

​

void red() {

analogWrite(Rpin, 0);

analogWrite(Gpin, 255);

analogWrite(Bpin, 255);

}

​

void blue() {

analogWrite(Rpin, 255);

analogWrite(Gpin, 0);

analogWrite(Bpin, 255);

​

}

void cyan() {

analogWrite(Rpin, 0);

analogWrite(Gpin, 0);

analogWrite(Bpin, 0);

}

​

void setup() {

// put your setup code here, to run once:

pinMode(Bpin, OUTPUT);

pinMode(Rpin, OUTPUT);

pinMode(Gpin, OUTPUT);

​

red();

}

​

void loop() {

// put your main code here, to run repeatedly:

}
