![]() ![]() Fine-tune the parameters of the Arduino program and the sound sensor's potentiometer until you get the desired results. Power the TV Loudness Guard and place it next to your TV. Update the TV Loudness Guard program with the remote control button code captured from step 1 and upload the program to your Arduino. There are three steps to make use of the TV Volume Loudness Guard:Ĭapture & decode your remote control Volume Down button (or any other remote function). ![]() This level can be changed in the program you upload to Arduino or with a potentiometer built into the sound sensor I am using in this project. When the volume loudness of your TV exceeds a certain threshold (set by you in the program or via a trimpot), the gadget sends a Volume Down remote control code to your TV-or any other remote controlled gadget for that matter-until the TV volume falls below the pre-set level. ![]() Place the Arduino TV Volume Loudness Guard close to the TV set to monitor the volume. The TV Loudness Guard should be part of every Big Brother's bag of tricks :) HOW THIS GADGET WORKS The TV Loudness Guard will be ready to keep a lid on it. Or when someone blasts the stereo system. There are many uses for this gadget such as keeping the TV volume down when you are in a different room while the kids are watching their favorite music channels. The TV Volume Loudness Guard will listen to your TV and if the volume goes higher than a certain level, it will bring it lower. I hope my TV Volume Loudness Guard will mitigate some of this ad-driven rudeness. But in many others, this TV audio terror is still legal. In some countries it's now illegal for broadcasters to blast the volume during commercials. What can be more annoying than those TV commercials on steroid? Here you are watching your favorite TV show when all of a sudden you are ambushed by a very loud TV commercial sending you scrambling for the remote control to turn down the volume. I have updated the Arduino program in step 4 to support additional remote controls. ![]()
