Add a video monitor to your Arduino using USB Serial TTL to RCA TV input
Add a video monitor to your arduino via serial !! You can use it as your
prefered output or as a secondary screen for the results of your sketch.
All you send through the serial will be printed out on your TV screen. (You
can use an old TV).
On Arduino, you must connect TX from arduino to RX (blue borne) of this my
rig adapter. Or on a PC, you can connect direct via USB cable.
