This kit is the best! I love using the 16×2 LCD screens in projects but they take up way to many digital io ports. The LCD117 fixes this and makes the LCD serial. Using ONE digital pin. Yeah!
The kit comes from moderndevice.com and comes preassembled or as a kit. Get the kit- it’s way more fun to build it. Pictures below.
The only deviation I made on the kit was to skip the resistor above the reset button. This resistor is for the display’s back light and I found that one wasn’t needed for my LCD.
