Now, it is time to program a LCD display with Arduino Micro. This can be used to monitor sensor data (Sensor information), date and weather.

LCD device and programming reference: Sunfounder Wikipage

This LCD has 4 lines (rows) and 20 characters (columns).

Each character position is set by lcd.setCursor(row, column)

We can use a lcd.print(“”) function to print out a message.

If we want to print out a mixture of characters and variables (ex: numbers), lcd.println(variable, DEC) can be called.

For time and date information, a real time clock (RTC) or GPS module can be used.

Next, start programming a sensor module.
