GhostESP lets you learn IR signals, store them on the SD card, and retransmit them using the onboard LED.
## Supported protocols
- NEC / NECext
- Kaseikyo
- Pioneer
- RCA
- Samsung
- SIRC (12-bit, 15-bit, 20-bit)
- RC5
- RC6
If a remote uses an unsupported protocol, GhostESP still attempts to capture raw timings so you can replay the signal.
