[+] and separate cathodes [-] for each color), the RGB LED uses an anode common to each color One solution is to use Adafruit or Sainsmart PCA9685 I2C PWM so that GND pins can be modulated. When using a PCF8574AT I2C adapter with the LCD, the GND trace to pin 16 needs to be cut off or the red GND cannot be modulated, and an extra header needs to be merged on pins 15 to 18 as shown in the picture.
My server stats can be viewed without switching on a monitor in this fashion. The whole thing- I think it's pretty good for a low price.
Nice features The contrast is decent, and the refresh is satisfactory. The cons are One pixel is the spacing between lines. As far as I know, this is the only character display I have. When red, green, and blue are all present at the same time, the result is a blue hue. It is common for RGB characters to appear in circles (I discovered this).
The materials I got were for a project my son was working on. I was on time, the work was done as described. This is an excellent.
At the time I bought it, I couldn't find it anywhere else for a cheaper price. The price seems really good when you look around. Aside from that, it works perfectly, and when combined with some other stuff it worked marvelously for the project I needed it to perform. There will definitely be more of these in the future.
The item is great and was delivered in a timely manner.
I have no issues with it.
I am pleased with the RGB display on this monitor. There is only one real flaw, which is that when all the RGB leds are connected, it becomes a blueish I'd like for it to be white. Other than that, it's fine. As shown in the diagram, the last three pins are grounds for the leds.
I was very pleased with how it worked. It was easy to hook up to my Arduino sketch on the R3 and up and running in no time. I would highly recommend it.
