An archery - Timer for FITA-tournaments using a Raspberry for controlling lowcost-hardware on the archery range.
This application is designed for raspberry Pi 1 (or later) with an external Touchscreen (ideal: 5" 800x480 px) Usage: steering of external hardware connected via external board-equipment (Hardwarelayouts in PDF File)
all overall a very simple program using the Raspis GPIO Ports
The LED and beeper-sequences correspond with the FITA - given regulations.
Phase 1) Beep and RED light for 10 Seconds -> Preparation
Phase 2) Beep and GREEN light for 210 Seconds -> Shooting
Phase 3) no Beep, ORANGE light for 30 seconds -> Warning phase
Phase 4) 3 Beeps, RED light -> End of circle
there is a possibility of "breaking" the shooting circle in case of emergency !
In one of the next versions i want to add wireless triggering of this.
If you need translations of the captions in the code, i can help
