In this lesson, you will learn how to setup your computer to use Arduino and how to set about the lessons that follow.

This is Lesson 1 in the Learn Arduino from Adafruit series. In this lesson, you will learn how to program your Arduino to make the Arduino's built-in LED blink.

This is Lesson 2 in the Learn Arduino Adafruit series. In this lesson, you will learn how to change the brightness of an LED by using different values of resistor.

This is Lesson 3 in the Learn Arduino Adafruit series. In this lesson, you will learn how to use an RGB LED with an Arduino.

This is Lesson 4 in the Learn Arduino Adafruit series. In this lesson, you will learn how to use eight LEDs using the 74HC595 shift register chip.

This is Lesson 5 in the Learn Arduino with Adafruit series. In this lesson, you will build on lesson 4, adding the facility to control the LEDs from your computer using the Arduino Serial Monitor.

This is Lesson 5 in the Learn Arduino Adafruit series. In this lesson, you will learn to use pushbuttons with digital inputs to turn an LED on and off.

This is Lesson 7 in the Learn Arduino Adafruit series. In this lesson, you will be combining some of the things that you learned in earlier lessons to use three push switches (from lesson 6) to control the color of the RGB LED that you used in lesson 3.

This is Lesson 8 in the Learn Arduino Adafruit series. In this lesson, you will start using the Serial Monitor to display analog readings, and then extend the project using eight LEDs from lesson 4, so that you can control the number of LEDs that are lit by turning the knob on a variable resistor.

This is Lesson 8 in the Learn Arduino Adafruit series. In this lesson, you will learn how to measure light intensity using an Analog Input. You will then build on lesson 8 and use the level of light to control the number of LEDs to be lit.

This is Lesson 10 in the Learn Arduino Adafruit series. In this lesson, you will learn how to make sounds with your Arduino. First, you will make the Arduino play a 'musical' scale and then combine this with a photocell, to make a Theramin-like instrument that changes the pitch played as you wave your hand over the photocell.

This is Lesson 11 in the Learn Arduino Adafruit series. In this lesson, you will learn how to wire up and use an alphanumeric LCD display.

This is Lesson 11 in the Learn Arduino Adafruit series. In this lesson, you will build on what we have learned in lesson 11 and use an LCD display to show the temperature and light intensity.

This is Lesson 13 in the Learn Arduino Adafruit series. In this lesson, you will learn how to control a small DC motor using an Arduino and a transistor.

This is Lesson 14 in the Learn Arduino Adafruit series. In this lesson, you will learn how to control a servo motor using an Arduino. Firstly, you will get the servo to sweep back and forth automatically and then you will add a pot to control the position of the servo.

This is Lesson 15 in the Learn Arduino Adafruit series. In this lesson, you will learn how to control both the direction and speed of a small DC motor using an Arduino and the L293 motor driver chip.

In this lesson, you will learn how to control a stepper motor using your Arduino and the same L293D motor control chip that you used with the DC motor in lesson 15.

In this lesson, you will learn how to use a PIR movement detector with an Arduino and to have the Arduino communicate with a Python program running on your computer to send an email whenever movement is detected by the sensor.
