Description
16x2 LCD key shield (5V)
Arduino UNO compatible
Can achieve six key functions and a rotary encoder function
3 Digital IO and 5 analog IO interface
The 16x2 LCD Shield Arduino Compatible is an LCD expansion board with a 1602 LCD display, a five-way key and a rotary encoder. It is fully compatible with the Arduino UNO board. You can achieve the desired display function only by connecting it with the Arduino UNO board, and then programming the corresponding code. In addition, a five-way key and a rotary encoder is there, and (D13-D11) Digital IO, (A0-A5) Analog IO containing SPI, I2C interface, so you can achieve key function on LCD1602 screen and encoder function, and you can also assemble the electronic bricks and many other modules with this LCD key shield, therefore, you can display the results you need on the LCD.
Uses the common liquid crystal library for easy control. I like the combination of rotary encoder and directional joystick. Can't complain too much at this price, but there is room for improvement: * Lower edge of LCD board lacks mechanical support (added dabs of hot glue) * Joystick contacts a little on the "insensitive" side, i.e. sometimes require very firm shove to register * "B" input of encoder unnecessarily hogs the second interrupt pin ("A" input uses the first interrupt, for good reason), forcing be to cut a trace and solder on a jumper to another pin for my application * No mounting holes nor sufficient open PCB real estate to bond brackets/tabs, on a board that will be subject to direct force by user
