First off, the Game Timer Pro looks awesome.
Can the relay run both a siren and a smoke grenade? If so, how would I set this up?
Alarm (I wanted something super loud): https://www.parts-express.com/alarm-siren-5-115-db-12-vdc–260-060?utm_source=youtub&utm_medium=youtube&utm_content=260-060
Smoke: http://sportsmoke.com/smoke-grenades/electric-fire/product/265-tactical-smoke-grenade-electric-fireButton Question: Can I replace the button with something larger and if so, do you have any recommendations?
Last Programming: I want to program the wires at the top to make it so all 4 wires need to be a closed circuit, vs open. Can this be done? I know you said in description that it’s now easily able to be programmed but ust not sure how.
To trigger both a siren and smoke grenade, you could use 2 relays both triggered by the detonation trigger connection. The trigger would just go to two relays instead of one.
Yes, I think that siren will work. You need a 12V source for it, and the relay would complete the 12V circuit for the siren. The second relay would complete a 9V connection to a smoke grenade.
You can connect an external button using the pads next to the button. This video shows an external switch connected: https://www.youtube.com/watch?v=kLG3BWkn8TM&t=3s
Yes, the code could be modified to detect when the wires are connected to ground instead of disconnected. If you are experienced with programming, I can give some details, but if not, then I’d recommend the Custom Programming item in our store, and I’d code/test that for you after getting your exact requirements. You would need a USB to serial adapter to use the Arduino IDE to upload the new code. Experience with that?
