Simulation Fake Bomb for Airsoft

Projects General Guidance
1

Hey everyone,

Brand new to the world of Arduino, and I'm here because I've come to find out that this is the best route for accomplishing my goal; an arm-able/disarm-able "bomb" for Airsoft. I've done a lot of digging and I've come across many different variations of the same idea, but they're all complicated and all have different ways of doing the same thing. The kind of thing I'm looking for is simple, but with no prior coding knowledge I've humbled myself very quickly in my attempts. I've messed around with Tinkercad for a few days and, while I'm feeling more comfortable with the construction, I'm still completely lost on how to tie everything together on the back end.

I also can't seem to find any good tutorials that are really going to help with this type of build. A few that I've done already have coding already written out and nothing that really explains how or why it's written the way it is.

End goal: An arm-able & disarm-able "bomb" that will give an added boost of simulation to a game type I've been toying with.

Features I'm looking for:

-Key switch On/Off
-Arm Button (Hold for 5 seconds to arm)
-Disarm Button (Hold 5 seconds to disarm)
-Automatic Timer of 10 minutes (or changeable on the back end, I don't want the players to be able to modify it in-game)
-LED On Light, that blinks during countdown
-Speaker and the ability to play sound clips for certain events. ("Bomb armed" when armed, "Bomb disarmed" when disarmed, beeping while it's planted, etc.

I'm pretty confident all of this is possible based on what I've read, but I still can't seem to grasp where to start.

If anyone knows any good reading material, or good tutorials that may help sharpen my skills I'd greatly appreciate it! I'm really excited to get started, I've been wanting to mess around with one of these for quite some time.

Look forward to the replies! Thanks in advance for the help!

This looks a fun project, I develop alot of laser tag stuff and this would not be to hard to do.

Don't use delays to start look at the examples folder for blink without delays, you will need at minimum:
-arduino nano
-audio sd module
-speaker (buy cheap dell pc 4 wire speakers +, -, audio in with built in amp)
-5v led
-2 buttons
-1 key switch

That is 2 inputs and 4 outputs roughly, start with buttons first, look at reading the buttons then use the no delay example and you should be able to time 10 minutes from the button press or stop timer on disarm.

Next add the led and blink once per second within the same loop, next upload sound to sd card and use SPI to control the playback.

I would use a Nano because they are cheap, small and you could use jumpers or solder the wires.

You may have to Google some things from this post but should point you in right direction possible extras voltage sensing of 9v battery, vibration motor for detonation.

Hope this helps.

Thanks for the reply Shandy! Boosted my confidence a bit! Im going to start looking into what you've mentioned and play around a bit more!

I’m really interested in the 5 second hold for the arming (I saw it in a model I found in my research, it showed a “loading bar” on the LCD as the button was held down. I want to add a bit of thrill to arming it, so if you release too early it doesn’t arm) but maybe thats something I can play with once I have some more basics under my belt, unless it becomes too difficult to manage.

I wouldn’t mind doing something exactly like this, just have a key on/off, two separate buttons to arm/disarm, and run a speaker or two for sound effects.

I may play around with the coding for this project once I get a better grasp for it.
