About this project

The background

Imagine this.

Kids watching TV, but the sound is too loud.

You are looking for the remote control to make it quitter but, it hides under the sofa.

In this scenario, I came out with the idea on static volume control.

Starting project

I wanted a small, decorative and static remote control, that can be on my salon table.

It will be nice if it can remote more then one device (like sound receiver).

The Challenges

  • Understanding that the device has to be small as Amazon DOT, forces me to use Arduino nano.
  • I used the IRremote library -that is simple to use.
  • To get the TV and sound receiver I assemble a simple board that uses a IR receiver- then I used the devices RC to get the IR code into the terminal.
  • I used the rotary encoder (see components) that have endless rotation, button and 2 leds.
  • I realized that while using a 9V battery, have around 600 mAh, and when testing the device - there was consumption of 23 mA- that means that the buttery life is around 27h- not enough. So I had to use a Power Save mode. After implementing the SavePower future, and cutting the power led- I got a consumption of 2.2 mA - that means up to 11 days without replacing battery, Not the best but good enough.

Schematics

The operation.

  • Pressing the rotary switch will wake up the device, to the previous mode.
  • Rotating clockwise will increase the volume.
  • Rotating counter clockwise will decrease the volume.
  • Pressing the rotary switch while device awake, will change the control device mode and rotary leds, and mute one device. - Green led means controlling the TV volume and Red led means controlling the sound receiver volume.
  • The control will enter sleep mode 10 seconds after last operation.
