Hello world! Today i made a ARDUINO AIRSOFT TIME BOMB, pretty easy to build. Be creative!

Take a look at the video to see the ARDUINO AIRSOFT TIME BOMB at work.

Arduino airsoft time bomb
Parts list:
Arduino UNO
Potentiometer (+ knob optional)
On/Off switch
1 Channel relay
lcd 1602 – Blue Backlight
4×4 Keypad
2x Red leds, 1x green led.
2x 220 Ohm (220 R) resistors
A set of MM FF MF Jumper wires
Female Power jack & adapter (optional) (You can also add batterys of course)
2 buttons for C & D(optional)
1 button for reset (optional)
Alarm Strobe? Alarm Sound?

(i used male and female audio plugs to connect the lamp)

The code in this ARDUINO AIRSOFT TIME BOMB has multiple tabs. So you need to add each code to a NEW tab.

Code: (Name it “Airsoft time bomb”.)

Code part 2: (Name it “Domination”.)

Code part 3: (Name it “Keys”.)

Code part 4: (Name it “Lang”.)

Code part 5: (Name it “Memory”.) this code is commented by default.

Code part 6: (Name it “Menu”.)

Code part 7: (Name it “Sabotage”.)

Code part 8: (Name it “Search and destroy”.)

Code part 9: (Name it “Splash”.)

Code part 10: (Name it “Zutils”.)

Good luck building your ARDUINO AIRSOFT TIME BOMB!

    1. Its in the codes, you can change language at the LANG code. The rest can be found in the menu code. Just read the code and try to understand the menu code and you will see what you want to do, you can add the second menu or totally change the menu options.

  1. followed your instructions and when i complied it to verify and transfer to the board it comes up with this error message what am i doing wrong ?

    Arduino: 1.8.5 (Windows 7), Board: “Arduino/Genuino Uno”

    C:\Users\simon\Desktop\Airsoft_time_bomb\Airsoft_time_bomb.ino:2:20: fatal error: Keypad.h: No such file or directory



    compilation terminated.

    exit status 1
    Error compiling for board Arduino/Genuino Uno.

    This report would have more information with
    “Show verbose output during compilation”
    option enabled in File -> Preferences.

  2. thaknyou for your reply danny can you tell me where do i get the keypad h library as i am a novice at this and still learning its probably a basic mistake but any help will be great thankyou.

  3. Hi Danny,

    Vraagje over de code. Maak het uit in welke volgorde je alles onder elkaar zet in het menu?
    Ik krijg enorm veel errors,

    Kan jij helpen?


  4. Hello, when I try to compile your code, this error appears
      AIRSOFT_TIME_BOMB.ino: 740: 24: warning: deprecated conversion from string constant to ‘char *’ [-Wwrite-strings]

        char * SABOTAGE_FAIL = “SABOTAGE FAIL!”;
    Might you help me? I am a newbie in Arduino and I apologize for my English I am using a translator thanks in advance

  5. Bedankt voor u heel interessante post. Maar het zou aangenaam en handig zijn moest je links voorzien van waar dat je welke onderdelen gehaald hebt. Wat voor “On/Off switch” is dat ?

    1. De on/off switch is origineel niet aanwezig, die heb ik gewoon tussen de batterij en arduino gezet. Deze heb je niet nodig voor het project, het is gewoon een optie die ik zelf heb toegevoegd. Staat ook niet op de schematic.
