Arduino: A Quick-Start Guide, 2nd Edition

Connecting the Arduino to Your TV Set

Even with a digital-to-analog converter in place, we still have a problem: the Arduino doesn’t have an RCA jack—that is, you cannot plug an RCA cable into an Arduino. We could attach an RCA jack to a breadboard and connect it to the Arduino, but there’s an easier solution. We’ll modify an RCA cable and connect it directly to the Arduino.

First, you have to cut off one of the cable’s connectors using a wire cutter. (See ​Learning How to Use a Wire Cutter​, to learn more about wire cutters.) Then remove about three centimeters of the cable’s outer insulation. Be careful, because the insulation isn’t very thick. Use the wire cutter to cut it slightly and then remove it by pushing it slowly toward the cable’s ...
