Review on Anmbest Interface LCD1602 Backlight Expansion by Justin Hollins
Facilitates the character display interface.
I have already used two of these I bought earlier on two other projects. I have a water valve control project that requires at least one more display, but I ordered five kits to have more. I always need some kind of debug display, usually spontaneously during project development. In any case, it's great. Just download and initialize the LiquidCrystaiI2c library and you're done.
- The contrast is adjustable and the blue potentiometer is turned clockwise to increase and counterclockwise to decrease. The backlight power control allows you to set whether to connect the backlight power supply through the jumper cap.
- Slightly torn
