 ## Demo
-[YouTube video](https://youtu.be/8EuNqTr02eU) of igniting fireworks using the Flipper Zero.  The signals broadcast from the subghz were pre-recorded ("Read RAW", config: 433.92MHz, AM650, RSSI -70) using a remote that was paired to the ignitor.  F_a1.sub and F_a2.sub were the files used in the video recording.
