arduinonerf

I’m building an Arduino Nerf sentry gun. In the previous post, I showed how I wired and mounted the trigger connector. Next, I needed a circuit to fire the gun from the Arduino microcontroller. To me, the most straightforward way to do this is with a small, 5V relay wired to a digital pin and ground of the Arduino.

I’m building an Arduino-controlled Nerf sentry gun. Rather than build it and present the finished project all at once, I decided to chronicle the build here on Make: Online. The first step was to add wiring and a two-wire connector to control the trigger circuit. I opened up the Nerf Vulcan (about 30 screws) and soldered an 1/8″ female jack to the fire selection mode switch.
