Hi, I'm doubting which LCD I should buy: [LCD w/ keypad Yellow-Green backlight and black text - off](https://www.tinytronics.nl/shop/image/cache/data/product-1415/lcd%20keypad%20shield%20green%20backlight-1000x1000.jpg) [LCD w/ keypad Yellow-Green backlight and black text - on](http://www.dipmicro.ca/img/1/BTE-ARD-LCDKEYG.jpg) [LCD w/ keypad Blue backlight and white text - off](https://www.tinytronics.nl/shop/image/cache/data/product-239/arduino%20lcd%20keypad%20shield-1000x1000.jpg) [LCD w/ keypad Blue backlight and white text - on](http://www.dipmicro.ca/img/1/BTE-ARD-LCDKEYB.jpg) Another possibility will be to buy a 20x4 LCD, but I haven't found a shield with buttons for a 20x4 LCD yet. Right now I have a 16x2 LCD with blue backlight and white text without a keypad. I will be using the LCD as a [digital clock](https://www.reddit.com/r/arduino/comments/7pyjev/digital_clock_with_many_functions_still_in/) which will be enclosed by a nice case
