One Existing Remote for All Audio Devices

Using the remote of an audio receiver/amplifier to control several devises…

This is the Instructable of the creation of an Aduino project to control all necessary devices like an Apple TV, TV Setup-box and Pioneer receiver by only ONE remote. In this case, it’s the remote of the Pioneer receiver.

Because I hate to use three different remotes and pushing several buttons to switch between TV watching, Spotify, CD and Radio music.

The Arduino has an infra-red (IR) receiver and picks up the codes from the only used remote. Than it transmits several IR codes to the different devises.

To listen to Spotify, push the selected button (TV/SAT) on the remote and the Arduino:

• Switches on the Pioneer receiver
• Selects the right source on the receiver (TV/SAT)
• Switches on the Apple TV to be used for Airplay from an iPhone or iPad

To listen to a Radio channel from the KPN TV Setup-box push the selected button (DVD/LD) on the remote and the Arduino:

• Switches on the Pioneer receiver
• Selects the right source on the receiver (DVD/LD)
• Switches on the KPN TV Setup-box
• Selects the Radio mode on the Setup-box

To play a CD push the selected button (CD) on the remote and the Arduino:

• Switches on the Pioneer receiver
• Selects the right source on the receiver (CD)

Pushing the TV/SAT, DVD/LD or CD button again the Arduino switches all the devises off again and puts the TV Setup-box back in TV mode.

There were also used four buttons on the remote to select different radio channels on the KPN TV Setup-box.

All electronics is built in one box with an external 5V power supply. A green led blinks when an IR signal is received. A red led blinks when the IR codes are sent.

A magnet inside the box and a metal washer and a some duct tape are used to keep the box in place in front of the audio equipment.

Step 1: Start the Project on a Breadboard

Best way is to start the project on a breadboard to test the configuration.

Find out what the IR codes are for all the devices and the buttons of the remote that should be used.

On Internet, there are many examples of Arduino projects to decode IR remotes. Use the original remotes of the devices to read the codes you need.

Partslist:

• 1x Arduino Nano
• 1x VS1838b IR receiver
• 1x 5mm 940nm IR Infrared led
• 2x 5mm leds
• 2x 220 ohm resistors
• 1x 470 ohn resistor
• 1x BC548B transistor
• 1x Box
• Some wire
• Some PCB prototype board

Step 2: Create the PCB's and Build a Box

Create the two PCB’s and build up the box.

Use an external 5V power supply and you are done!
