Arduino Control for Pyro Ignitor

I need an Arduino program to control time delay relays for a pyro ignitor. The ignition will be triggered by a manual switch and/or remote. I need the first relay to trigger 5 seconds after button or remote is pressed. Then five more, for a total of six, relays will trigger every 25 seconds. Another button or power switch will be used to terminate the cycle. Relays trigger on for a duration of a half second then turn off.

Requirements:
- Program Arduino to control time delay relays
- Integrate with manual switch input
- Ensure safety and reliability for pyro ignition

Ideal Skills:
- Proficiency in Arduino programming
- Experience with time delay relays
- Understanding of safety protocols for pyro applications
