Convenient illuminated keypad for automotive use

This keypad expansion gives my garage an upgraded high-tech feel while making it easy to control my automotive equipment. The backlight is a great feature that makes it easy to use in low-light conditions. The installation was straightforward and it is compatible with several different pieces of equipment. The only downside is that it can be a bit pricey compared to other keypads, but the quality and convenience make it worth the investment.

Pros
  • Easy to install and use
Cons
  • The backlight may flicker in low light conditions

Good item for a reasonable price.

This shield works well with Arduino and Maximite. The only thing I can do about it is that if you can't see text on the LCD, the contrast adjustment is a small screw on the blue piece of plastic in the top left corner.

Pros
  • It features a contrast adjustment knob, a backlight selector switch, and four directional buttons, a select button and a reset button.
Cons
  • Reliability

Pros
