 Arduino library to make ammo counters and more for highly modified NERF blasters.

+#### Features Included:
 1. **Ammo Counting:** Count your ammo. Whenever you fire a dart, it's detected using one of these methods:
 	1. **Switch**: Detect shots every time the trigger is pressed. Orient a tactile switch to be pressed when the blaster's trigger is pressed, and wire it up to the microcontroller. May not be ideal for fully-automatic blasters.
 	2. **Infrared (IR) Gate**: Using both an IR transmitter diode and IR receiver diode to detect dart passage rather than physical trigger pulls. The transmitter and receiver should be positioned so the transmitter shines directly on the receiver along the diameter of the barrel, forming a "gate". When a dart is fired, the gate is broken, which is detected with the microcontroller.

 7. **Count-Up Mode**: Instead of counting down, it can count up every time a shot is fired.

+### Hardware, Parts, and Tools Needed
 All builds require some sort of Arduino-compatible microcontroller. I recommend the [Adafruit Pro Trinket](https://www.adafruit.com/product/2000). Also make sure to have the [Arduino IDE](https://www.arduino.cc/en/Main/Software) installed.
