USB Volume Control and Caps Lock LED

p_leriche @ instructables.com build a USB volume control which is simple, cheap and extensible. Check it out:

I’m not the first person to publish an Instructable for a USB volume control, but I think this one is about as simple and cheap as it gets, and at the same time can be extended at minimal cost to various other functions such as:

  • Mute, Play, Pause and various other media buttons
  • Keyboard LEDs such as Caps Lock, Scroll Lock and Num Lock (a kana LED is also defined for Japanese users)
  • Application launch buttons such as browser, email, calculator etc
  • Browser navigation and other application control buttons
  • Gamepad buttons
  • System buttons for functions such as Sleep, Hibernate, Wake, Power down
  • Mouse buttons and movement

and many more, subject to support being provided by your operating system. Mine implements the volume and mute functions (mute by pressing the knob) and the 3 main keyboard LEDs.

How to control Arduino board using an Android phone

Arduino_android

Kerimil, user on Arduino Forum, submitted his project which focuses on establishing communication between an Arduino board and an android mobile using bluetooth:

The idea is to gain access to hardware on Android devices (accelerometers, gyro, wifi connectivity, gps, GPRS, touchscreen, text to speech and speech to text) and/or use it to relay data to the internet. MIT’s app inventor was used to write a custom app in this example. The code can be easily modified to create your own apps.

One Channel Infra Red Remote Controller

H015-500x500

One Channel Infra-Red Remote and receiver with onboard Relay provides normally open and normally closed output. The project based on PIC12F683 Microcontroller from Microchip , TSOP1738 used as Infra-Red receiver. Micro-controller decodes the RC5 serial data coming from TSOP1738 and provides high output if the data is valid. The output can be set Momentary or Latch using on board Jumper (J1) and closure. The board provided with 3 LEDs, Power LED, Valid Transmission LED and Output LED. This Remote works with switch No1 of RC5 Remote.

Features

  • Power Supply Remote 2X AA Batteries
  • Power Supply Receiver 7-12V DC
  • Current Consumption Receiver 30mA
  • Onboard jumper for momentary and latch operation selection
  • Transmitter range 10-15 feet
  • RC5 (Philips) Remote
  • Onboard power LED
  • Onboard output ON/OFF LED
  • Onboard Valid Transmission LED
  • Onboard 5V regulator
  • PCB Dimensions 59.06 MM X 29.53 MM

How to Build a Control Circuit with Adjustable Working Time via Wi-Fi

ESP8266BreakOutBoard

In this article, you’ll learn how to build a system that can turn DC loads on and off using a mobile application. You’ll also learn how to perform this task via immediate actions or via timers set in advance for switching loads on and off. by Yahya Tawil

You can implement this system in environments where you need to set your DC load for a specific time. This will allow you to use our Android application without any need for a hardware interface, keypad, and LCD screen.

Arduino IR remote and Software controller

IR_remote

This is a DIY Infrared remote for speakers, replacing the original. Arduino Nano and controlled via a custom .NET application and placed in a laser cut enclosure.

This one is an interesting one, it’s something we’ve been looking at for a while and figuring out how to solve it. We have sets of speakers and projectors and the users keep losing the remotes, or misplaced/stolen. Usually this wouldn’t be a problem, we’ll just contact the supplier or manufacturer and order replacements. Except we can’t any more.

We have a set of Vision AV-1000 wall mounted active speakers, connected to an EPSON projector. Projector remotes are easy to come by, but the AV-1000 remote is no longer manufactured. The speakers do not have any manual controls for the input selection, bass/treble etc. only a volume control on the back.

Control ESP8266 over the internet

F8H4C1WIN3EI8A1.MEDIUM

Here is a basic tutorial on how to control ESP8266 over the internet using two buttons on a browser window. The article goes through Arduino IDE configuration and example code is included.

There are but a few things better than (succesfully) programming and using your Arduino. Surely one of those things is using your ESP8266 as an Arduino with WiFi!

Controlling Arduino using your Voice

FO5AMNEILID0Z6P.MEDIUM

bluehybrid @ instructables.com shows us how to use your voice to control a led light on Arduino. To achieve this he used the 1Sheeld Arduino shield.

This Project is getting start to use arduino with 1Sheeld

In this project we will turn an LED (ON) and turn it (OFF) by Voice

We will say “Open” to turn it (ON) and “Close” to turn it (OFF)
