In this example we will add an Arduino LCD keypad shield to a ST Nucleo F334R8. This is a 16x2 LCD Keypad module for Arduino Diecimila Duemilanove, UNO, MEGA1280, MEGA2..
In this example we connect a low cost PIR to our NUCLEO-F334R8 board and if an intruder is detected we will display a message. A passive infrared sensor (PIR sensor) is.
