Hardware Overview: Arduino Course for Absolute Beginners (ReM)

What are all the components on that aesthetically pleasing blue Arduino circuit board? What does GND stand for, and what is with the “~” mark next to those plastic lifted holes mean?   This tutorial covers the hardware on the Arduino board that you will likely use as you work on projects. It is by no means a comprehensive study of the physical layout, but enough to make you familiar with the parts you will be using.  

Displaying GPS NMEA Data in Google Earth

This video shows a step-by-step tutorial on showing data from your GPS on Google Earth. The project uses the Adafruit Ultimate GPS board and an Arduino Microcontroller. The lesson shows how to properly configure GPS coordinates from NMEA sentences into a KML file that Google Earth can display. For more info, see Arduino LESSON 25 at, where we have the code and supporting material.  

Build an Arduino GPS Tracker

This tutorial has step-by-step instructions on creating a GPs tracker based on the Arduino and Adafruit Ultimate GPS breakout board. This lesson will get the circuit connected, and the module streaming and reading good NMEA sentences. In lesson 23 we will parse the data and save to an SD card.  

Measure Distance with Arduino and Ultrasonic Sensor

In this tutorial we show simple step-by-step lesson on how to measure distance with an arduino microcontroller and an ultrasonic sensor. The measured distance is based on the ping time to the target of an ultrasonic ping. The measured distance is displayed via a servo and hand drawn scale. The sensor used is the virtuabotix ultrasonic sensor, and the servo is from the Sparkfun Inventor kit. Key concept in this lesson is to show students how important it is to apply what they know from Algebra related to lines in order to map inputs (distance measurements) onto outputs (servo angle)….
