Servo driven Konfetti Gun with Arduino

grabcad

This is a modified Konfetti gun. It's a joke article one can buy online and in this modified form, it is quite good for surprises.Unscrew the 3 screws, drill 2.2mm holes through holes instead and use metric M2 screws to attach the gun to the holderA servo is pulling the trigger and an arduino is attached to that servo. You can connect different types of sensors to trigger the gun. I used a sonar sensor, which does a reliable job and works between 10cm-400cm.The Servo has 12.39 kg-cm. That works but it should not be weaker.There is a DIP- switch integrated to run in 3 modesSimulation mode- just an LED is blinking when triggeredSensor mode- attached sensors triggers signalTimer mode- timer triggers the servoThere is also circuit diagram attached and of course an arduino file.NOTE:Even if this is a joke article, do not directly point this thing at people!!
