Install TVOut Library\n\nInstall the **TVOut** library in the Arduino IDE.\n\nThen copy the folder:\n\n```\nTVOutFonts\n```\n\ninto:\n\n```\nArduino/libraries/\n```\n\n---\n\n## 2. Upload the code\n\nUpload the provided **.ino sketch** to the Arduino Nano.\n\n---\n\n## 3. Connect the TV\n\nConnect the **RCA cable** to the **VIDEO IN** port of your TV.\n\nAfter reset, characters typed on the keypad will appear on the screen.\n\n---\n\n# Notes\n\n- One keypad provides **10 keys**.\n- To cover the full alphabet you can connect **three keypads** and map additional characters in the sketch.\n- The video signal is **composite NTSC**, generated directly by the Arduino using the **TVOut** library.\n\n---\n\n# Contact\n\n**Roni Bandini**\n\nLinkedIn  \nhttps://www.linkedin.com/in/ronibandini/\n\nInstagram  \nhttps://www.instagram.com/ronibandini/\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fronibandini%2Ftv-typewriter","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fronibandini%2Ftv-typewriter","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fronibandini%2Ftv-typewriter/lists"}
