I recently completed an independent school project for which I designed and built a prototype of a hand-held sensor platform. It consisted of an ATmega328, a ST7565 LCD and a couple sensors. I ended up using the Arduino environment with Adufruit Industries’ ST7565 Arduino library. Being tired of writing new code every time I wanted some sort of LCD user interaface, I set out to create my own API on top of Adafruit’s library.
The basic structure I was after was a menu based UI, involving layers of menus and sub-menus, each consisting of different selectable items, whose functions were all user-defined. This ended up being an easier task than it sounds, and I ended up with a rather cool library which I’ve dubbed the exceedingly creative name of ST7565 Menu
Four mounting holes and a blank 11 pin 2mm-pitch labeled breakout on the side – we just soldered some wire to each hole as shown in the photos, its very easy. (The LCDs have no wires soldered in when we ship them)
Bonus! We’re including a free 4050 level shifter chip so that you can safely use it with your favorite 5V microcontroller
Lower cost than KS0108 LCDs
Serial interface uses only 4 or 5 digital pins
Low power, full-color RGB LED backlight
Visible in daylight without backlight
Works perfectly with 3V logic
3.3v power and logic means a level converter is needed for 5V Arduinos (we include this part when purchasing from us)

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
