# Bluetooth stroboscope controller

This is an Arduino sketch for a Bluetooth stroboscope controller. It receives commands from the HC-05 module and generates required flashing signal.

## Set up

This sketch is running on the 5V Arduino Pro Mini. The HC-05 module is connected directly to RX and TX pins. Flashing output is directed to S750's audio in.

## Command protocol

| Name | Code | Payload | Example |

| -----|------|---------|---------|

|Single flash|0x1|-|`0x1`|

|Stop|0x2|-|`0x2`|

|Continuous flashing (Hz)|0x3|unsigned byte of Hz value|`0x3 0x5` — start flashing at 5 Hz frequency

|Continuous flashing (BPM)|0x4|2 bytes of unsigned short BPM value in **Little endian**|`0x4 0x4 0x1` — start flashing at 260 (0x104) BMP frequency|
