The TellyMate Shield equips an Arduino with the ability to send simple text and graphics to a TV. The TellyMate Shield connects to an Arduino board using long headers which extend through the shield. This keeps the pin layout intact and allows another shield to be stacked on top.
Arduino uses digital pin1 (TX) to communicate with the TellyMate. Just plug it into your Arduino and use Serial.println() commands to output text onto your TV!
The shield provides a 3.5mm jack and the necessary cable to convert to a composite video connection. The baud rate is selected by jumpers, which are also included.
