Television Remote

429 views

Even though the month of March had gone by fast , it is a month of television watching and switching through various channels. This phenomenon is all because of one event: March Madness. Overall, those two weeks I had spent a good portion of my time at home in front of a screen. So when it was time to write a blog post electricity became an easy topic to write about. Especially because during class we had recently finished a unit on electricity.

From what I have learned in class as well as doing some research I had found that the logistics of a television remote are actual quite simplistic. So simple that by pushing a button on a remote control sets in motion a series of events that causes the controlled device to carry out a command. The process can be summed up within three steps. On, You push the volume up button on your remote control, causing it to touch the contact beneath it and complete the volume up circuit on the circuit board. The integrated circuit detects this. From there, the integrated circuit sends the binary volume up command to the LED at the front of the remote. Finally, the LED sends out a series of light pulses that corresponds to the binary volume up command. Though the basics of this seems to be simple, interference within the connection of the circuit can be complicated at times.

It is crazy to see how something we enjoy and unit with is full of physics!
