Tutorial: Arduino Lesson 11. LCD Displays (Part 1 & 2)

Overview-6

Overview-1-1

Tutorial: Arduino Lesson 11. LCD Displays (Part 1) @ Adafruit Learning System and here’s part 2!

In this lesson, you will learn how to wire up and use an alphanumeric LCD display. The display has an LED backlight and can display two rows with up to 16 characters on each row. You can see the rectangles for each character on the display and the pixels that make up each character. The display is just white on blue and is intended for showing text.

In this lesson, we will run the Arduino example program for the LCD library, but in the next lesson, we will get our display to show the temperature and light level, using sensors.

In second part of the lesson, you will build on what we have learned in part 1 and use a LCD display to show the temperature and light intensity.  

Light intensity is measured using the same photocell that you used in lesson 9.

To measure the temperature, you will use a temperature measurement chip. This device has just three leads two for 5V and GND and the third lead is connected directly to an analog input on the Arduino.
