The library also includes one example sketch (volume) for a simple exercise. The proposed hardware setup is very easy — just connect the CLOCK (Pin 5) of M62429 to D6 of Arduino while routing its DATA ...

Once the sound has been detected to have dropped down below a critical vaue, the Arduino assumes that the movie is back to dialog and will increase the volume by the number of times it decreased ...

By the way, we’ve covered a PID library for Arduino before. While this post talks about temperature, PID control is used for everything from flight control to levitation.

This Instructables guide will show you how you can use an Arduino to control your TV, DVD player, VCR, and countless other home electronics.
