RFID Domination Timer firmware - Airsoft stopwatch

I offer firmware for RFID Domination Timer project that is based on AVR ATmega328P chip (Arduino) architecture. In price is included machine code .hex for that architecture for your RFID cards that you have provided via Google Spreadsheet teamplate. Also there is included .lppz archive for PCB manufacturing with drilling, layers inforamtions etc. I don't offer source code in .ino format or hardware with PCB.

STOP ASKING IF I CAN SHIP DEVICE! I am selling firmware for this price. I am not selling 200 EURO device for 40 EURO.

Project description:
Domination timer (DOMINATOR) is a stopwatch device designed for 2 teams (scalable up to 4 teams) that play against each other and try to occupy the point and keep it for as long as possible. The stopwatch is suitable for Airsoft / Paintball game mode DOMINATION, resp. Capture Hill. They consist of an ATmega328P microcontroller (AVR), which can be part of the Arduino development kit (Uno / Nano / Pro Mini). An LCD character display (size 16x2 or 20x4) is used to visualize the times. 

The times are listed in two lines below each other and are dynamically updated if there is an active team at the point (a point occupied by a team). The stopwatch is equipped with indicator LEDs in team colors, which signal the active team at the point and a detector (piezo transducer), which announces the change at the point after attaching the RFID card. Teams are implemented in the game - RED team and GRE team who play against each other and try to occupy the point and then keep it for as long as possible. At the beginning of the game, the display shows the times 00 hours, 00 minutes, 00 seconds for RED team , GRE team . 

Each team member is equipped with an RFID chip that is integrated into the bracelet (or card / keychain). The RFID chip transmits its unique identifier - UID (unique ID), which is read by an RFID reader and verified in the logic of the system to which the entity (team) belongs. Individual bracelets can be color-coded (red, green by team and entity function), which allows them to be distributed more quickly to players, but also archived and stored by color. The RED team will occupy the point when the RED team member attaches his card to the RFID reader. This action triggers a buzzer that announces the change of point with a short beep. 

Subsequently, the LED of the RED team at this station will light up and the display will start adding the time for this team until the member's team card is inserted, Referee , or Eraser. If the point is occupied by a GRE player and the card is attached to an RFID reader, the buzzer will announce this change with a short beep, the GRE LED will light up (RED LED turns off), RED's current time stops , and GRE's time is scored. If the Referee attaches his RFID card, the running time will stop at the current value. 

The point becomes neutral, the active team's LED goes out. The stoppage lasts until a member of the RED team or the GRE team presents their card. This type of card is thus suitable for temporarily stopping an ongoing game, controlling a player's intervention, or injuries. At the same time, the card can be used at the end of a round of the game, to evaluate the round, respawn teams before continuing. If Eraser attaches the card, both times will stop and reset to the initial value of 00 hours, 00 minutes, 00 seconds, which will be displayed. The Eraser card is used to restart the game, to initialize a new game without the need for a power-on cycle. 

The RFID reader responds to the insertion of an RFID card immediately, including the entire logic of the Dominator project. The project is suitable for Airsoft events, sports facilities, or Airsoft teams, which can build a Dominator device with their own hardware. Firmware is universal for Arduino Nano / Uno or standalone ATmega328P chip, it is also possible to use the available PCB design for the production of printed circuit boards (PCB using Arduino Nano only!). The advantage of the RFID Domination timer project is that the usage license authorizes the user to clone and create X points with the same configuration via machine code. 

Machine code (.hex) is a compiled firmware format for the RFID Dominator project for supplied UID RFID cards that are embedded in the code before compilation. It is thus possible to place any number of independently operating RFID Domination timer points in the game, which respond to identical RFID cards according to a uniform configuration. The RFID Dominator system is programmed well, it exist from 2018 year, it can be put into the game immediately. Firmware uploads within 10 seconds via XLoader (recommended software).

Project hardware - RFID Domination Timer: 
Arduino UNO / Nano / standalone chip ATmega328P (with 16 MHz oscillator) 
LCD 20x4 or 16x2 (20x4 layout is used in PCB design) 
I2C module for LCD display 
RFID reader RC522 (13.56MHz) 
ISO / IEC 14443-A standard keychains / cards / bracelets 
Passive buzzer (optional) 
2x LEDs, 2x resistor (1x 220 ohm for GREEN LED, and 1x 1 kohm for RED LED) 
2x resistor 10K I2C pullup (optional, useable for larger distance between display and Arduino) 

Software is delivered in machine code (.hex) at your mail for the ATmega328P architecture (if you want via post, I can print it on 30 papers and send via post, and you can copy paste it char by char, as some of you dont understand what is firmware and hardware). The price is for 10x RFID UID for each team and 2x for the Referee and Eraser, total of 24x UID. If you want to increase the number, it is possible for 5 GBP / another 5 UID. The machine code cannot be modified and is tailor-made for the authorized operator based on the UID, which it delivers in .xls format (the template is available on the project page with an extended project description). It is possible to try for free one UID for each entity in project (ping me at mail for that).
