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 8 in the Learn Arduino Adafruit series. In this lesson, you will be start of 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.
Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. It has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen. This tutorial will teach you how to use this shield with your Arduino.
