LCDs, Servos, and Twitter4j

Interested in expanding your projects with LCDs and Servo motors, or even sending a tweet with your Arduino?  This video course walks through setting up these devices/software and programming them with Arduino code libraries.

What will I learn?

  • Using Liquid Crystal Displays with Arduino
  • Using buttons and potentiometers as inputs to your GUI (graphical user interface)
  • How to power your Servo Motor
  • How to program using the Servo library to control your Servo Motor
  • Using Processing and the Twitter4J library to send a tweet with the Arduino


This course assumes you have a solid understanding on the Arduino platform and understand topics like libraries, and functions. If you have finished the Arduino Course for Absolute Beginners – then this training will be right up your alley.

Required Hardware

  • Arduino Compatible Board
  • Liquid Crystal Display Module (LCD) with parallel wiring (a 16 x 2 is used in the course, but other sizes should work fine too)
  • Servo Motor (You may want to watch the first couple servo videos, before deciding on a servo.)
  • Pushbuttons (4)
  • 10K Ohm Resistor (4)
  • 10K potentiometer (2)
  • Solderless breadboard
  • Jumper Wires


"fantastic course. I learned a lot and used it to jumpstart my robotic interests."
-Peter Call, NJ, USA

"...your lessons are concise and challenging....I have the ability to asses new code and problems and deal with them quickly"
-Jaco Coetsee, Langebaan, ZA

Course Description

This course covers several different topics, and is sort of an "add-on" to our main Arduino Course for Absolute Beginners Course.

If you answer yes to any of the following questions, you're in the right place:

  • Are you are interested in using an LCD for a graphical user interface (GUI)?
  • Do you want to control Servo Motors using an Arduino?
  • Do you want to get familiar with the process of working with another program (Processing) in tandem with Arduino, to send a “tweet”?


Length of Instruction: 4 hours and 31 minutes of HD video instruction.

Import Notes:  The type of LCD demonstrated in these lessons is the common Hitachi HD44780 (or a compatible) chipset (Not the I2C versions).

"Your courses are simply the best out there and have given me insight to how to help with this project. Thank You very much."
-Michael Myers, Longview, TX

"Armed with your information, last evening I was able to assemble the code to make an Uno read values from a Type-K thermocouple in Fahrenheit and output this information to a 16x2RGB LCD screen.

Cannot express the feeling I had when I saw something beyond Hello World!"
-Ken Quimby, Maumelle, AR
