Hey all, I recently rigged up a round counter/chrono/voltmeter/volt alarm gadget to add to my son's collection of nerf things. This project is more in line for the custom builders/diyers, especially those adept with Arduino stuff. The pinout is written at the top of the code (please note this is ported 328p specific). This should be more than enough info for those willing/able to make one of these to proceed with success.
What does it do: It constantly measures voltage and warns the shooter of a low battery (long beep + highlighted Voltage value). The low voltage alarm threshold is automatically set (for 2s and 3s lipo only, as coded... I may add more options if ppl need). It measures and stores FPS, RPM, and voltage for every dart fired from the clip. After the clip is empty, min/avg/max values are displayed for FPS/RPM/Volts, then tables are scrolled through showing all of the dart data in the order fired (max/mins values are highlighted). The method of timing used for FPS yields +-65nsec precision (~30000 counts for a 100FPS Elite dart... overkill really). More details are written in the comments in the top of the code. Other than that, it's a pretty dumb code that could be improved upon for your specific application (recode it for clip reed sensors, etc...). 
How do we get FPS with 1 sensor: We know more or less the dart length, so we know how fast it is from how long it blocks a single sensor. This means variances in dart length go in to speed calculation. This is not a problem with 2 sensor FPS measurement, but the simplified hardware is well worth it as long as we understand we get some relative measurement errors due to dart length. Note that if we are really needing to go 2 sensors, we could wire both sensors to the same pin using a simple circuit, and change the code to interrupt on a pair of falling edges instead (vs a falling then a rising edge). Then a 2 sensor barrel can be used with this code no problem!
Some folks would say I'm not smart for sharing this code here. I personally hope that posting my code will result in it being 'borrowed'... hopefully we'll see these ideas make their way in to the current crop of commercially available ammo counters. Those folks making those things probably won't charge extra for these features anyways (takes less time to solder i2c than 7-seg anyways, LOL). That would be IMHO a big plus for Nerfers. I'm not putting time in to make/sell these myself, so please don't bother asking.
Items needed:
16MHz 5V 328p (I used a spare pro-mini)
OPL550 IR photo logic sensor
OP240a IR photo diode + 100ohm 1/4W resistor
128x64 I2C SSD1306 monochrome display
LM7805 regulator (I used a spare TO-220, but this won't drawing much over 100mA anyways)
0.1uF & 0.33uF output/input anti-ripple caps for the above regulator
5k6 & 3k3 resistors (10% is OK)
LED + limiting resistor (you pick... stay under 20mA since it's pin driven)
5V peizo buzzer (doesn't require tone libraries... 5V in = buzzzzzzz)
3@ momentary NO buttons
Nerf Scope of choice (must obviously fit stuff, and must be hacked as needed)
Notes:
1- The 5k6 and 3k3 resistors make a voltage divider which is used to read your main Nerf battery. These values are good for batteries up to 13.4V, which should work for most. If you need more (like 4s), please adjust the values accordingly... vbattRatio will also have to be adjusted to match your divider.
2- A 100ohm current limiting resistor for the photo diode was needed for a 1 1/4" PVC barrel adaptor I made for mega darts. However this may result in a somewhat shorter doide life. If your sensor/diode will be less than 1" apart, 150ohm will work and will last forever.
Oh yeah baby... modular nerftec!!! (the Deans plug taps in to the Stryfe's 2s lithium battery, for both power and voltage monitoring)
Fugly breadboard action... that extra multi-turn poti is there just to simulate low battery alarms for testing/debugging (not installed):
Dryfitting the guts in the scope before cutting and soldering the wires:
Shameless blocking splash screen, LOL...
Setup mode after boot, we see live voltage, and can setup clip capacity and dart length...
Fire mode, with live voltage, round counter, 1 round left LED (w/ single beep), 0 rounds left 3 beeps...
Empty mode min/avg/max values, and live voltage... (yes this photo was shot before I fixed a typo bug in the avg& max voltages;) )
Empty mode per dart data tables, with highlighted max/min values...
Here's the code (I'm compiling with Arduino 1.8.1):
#define versionNo "1.U"
/* nerfGunU.ino
* by: Kevin B.
*
* Nerftec... deeper down the rabbit hole.
*
* Note: U=T, with a workaround for input capture interrupts resulting in failure of the
* 'last buzzer off' command. Version ID is also #defined for convenience.
*
* Overview:
* A Nerf gun chronograph/computer, which uses an IR emitter/detector and OLED display
* to show remaining rounds, voltage, fps, and rpm. This is taken to the next level with
* post clip averages and dart data tables with highlighted max and min values. The code
* is all non-blocking, uses direct port access (versus digitalRead/Write), and Timer1
* input capture methods, ported for a 16MHz m328 target. An OPL550 IR sensor with an
* OP240a IR emitter work well for the applications used by author of this code (100ohm
* on the emitter >1" from sensor). The pair are mechanically matched and posess a sub
* clock response times, which goes well with the +/-65ns input capture methods used
* (with a 550/240 set, any measurement error will stem from dart length variances). The
* code is also written for use with a Banggood 0.96" 128x64 i2c monochrome OLED screen
* (SSD1306). Other displays and/or targets may be used... just be mindful of your portD
* and Timer1 pinouts.
*
* Operation:
* Setup mode: Boots in to setup mode, where the screen guides the user to adjust clip size
* and dart length. Upon entering setup, the clip size value is highlighted, and pressing
* the right or left buttons will adjust capacity. A short click of select will highlight
* the dart length, which can then be adjusted with the R/L buttons. Holding the R/L buttons
* in dart length mode will jump between Mega and Elite defined lengths as a convenience.
* Live voltage is displayed on the bottom. Holding Select will go to fire mode.
*
* Fire mode: When entering fire mode, the LED turns off, and live voltage, FPS, and RPM
* are displayed under remaining rounds. When there is one round remaining, the LED will
* turn on and the beeper will emit 1 short beep. When the clip is empty, the beeper emits
* 3 short beeps and the code enters "Empty Mode".
*
* Empty mode: Upon entering empty mode, a statistics page is displayed showing Min, Avg,
* and Max values for FPS, RPM, and Voltage. Live voltage is also show on the bottom of the
* page. After a few seconds, dart data tables are shown. The tables list round #, volts,
* FPS, and RPM for all rounds fired, with highlighted max and min values. Hitting the
* select button returns to fire mode using the previously selected clip size and dart
* length. Either the right or left button will return to setup mode.
*
* Low voltage warning: After boot up, voltage is checked, and the low voltage threshold is
* set to 6.4 or 9.6V, depending the the inferred source (2s lithium or 3s lithium). On
* screens where live voltage is available, the value will be highlighted when it drops
* below the threshold. In all modes, if the battery is low, the beeper will emit one long
* beep. If voltage remains low, the long beep will repeat after the defined warning delay.
*
* Physical wiring:
* Pin________Connected to_________________________
*
* A0 Vbatt divider (default: 5k6:3k3 divider for 13.4V max)
* A4 OLED SDA
* A5 OLED SCL
* D3 Select button
* D4 Right button
* D5 Left button
* D6 LED indicator
* D7 5V Buzzer
* D8 IR Sensor signal
*
* ***D0-8 are ported for m328 (Uno, etc)...
* Please verify/edit to match portD & Timer1 pinouts for other targets
