Motors, LEDs, SD Cards, Relays and More
I think of this classification as just about anything you control to provide and output to the world. Displays are included, but I give them their own classification HERE.
I’ve played with each of the devices you see listed and each of the articles contains enough information to get you started.
 | Making Small Toy DC Motor Work with an ArduinoMaking things move with an Arduino is part of the fun. This tutorial lets you power your first motor. READ THIS ARTICLE |
 | Controlling DC Motor Speed with an ArduinoOne you make a small DC motor spin, the trick is to control the speed. Back in the day, this was often accomplished by changing the voltage, where a higher voltage meant a faster speed. On an Arduino, you will use Pulse Width Modulation to control the speed READ THIS ARTICLE |
 | LC Studio SD Card Arduino TutorialThis little number worked great for me the first time. I’ve included not only hook ups, but an introduction to reading and writing to an SD card. Has sample sketches, hook ups and pin outs. READ THIS ARTICLE |
 | 5mm LED Arduino TutorialThis Tutorial picks up where ‘blink’ leaves off. Its intended to provide the knowledge you need to make successful use on an LED in your next project. It includes a project schematic, and two sketches. READ THIS ARTICLE |
 | 5 Volt 4 Channel Relay Arduino Relay Module Manual and TutorialThe Four Channel Relay Module (found all over the place), makes short work of controlling devices that operate at higher currents and different voltages. With these, you can control devices like motors and lights. READ THIS ARTICLE |
 | MCP41010 Digital Potentiometer User Manual and TutorialDigital Potentiometers are just one way to programmatically control a voltage output from your Arduino. This article focuses on the MCP41010. You will find a functional description and a tutorial. READ THIS ARTICLE |
 | KY-008 Arduino Laser User Manual and TutorialThis device is ideally fit for an Arduino. Its low power consumption means that you can power it directly from an Arduino digital IO pin. What that means is you will only need two wires to make it work. READ THIS ARTICLE |
 | Arduino 12V Automotive Relay Tutorial with a TIP122Automotive Relays are cheap and very reliable. This article is worth a read even if you don’t plan on building anything for your car. Its a great way to move a lot of current with your Arduino. READ THIS ARTICLE |
 | Using a 10W LED with an ArduinoThe High Power 10W LEDs are cool devices that are begging to be controlled by an Arduino This article will show you how to do just that. Includes sample sketches and schematics READ THIS ARTICLE |
 | Using an LM317 To Control LEDs with your ArduinoLEDs are often best controlled with current. An LM317 and a TIP122 will help you to do just that. It will show you how to drive LEDs in series using the same Arduino output. Has schematics and a sample sketch. READ THIS ARTICLE |
 | MCP4725 DAC Arduino TutorialThe device allows you to program a voltage output using your Arduino. It does so in increments of 1.2 volts when it has a 5.0 supply It communicates via I2C. READ THIS ARTICLE |
