Many people are not aware that a humble Arduino board is capable of producing an output to a TV. Welcome to the second post in our “Skill Sunday” series! This week we are going to teach you how you can connect your Arduino to your TV. The best thing about this project is that it is really easy. All you need is a RCA cord and some resistors, and you can be generating fantastic black and white graphics on your TV in no time.
Once you have hooked up your Arduino to your TV, the possibilities are endless. You could display sensor data and graphs on your TV, enjoy remakes of classic games such as pong or even send messages to your TV from a keyboard.
