If you want to get information about whole firmware, visit my other advert, where I offer firmware without hardware!

I offer a programmed RFID Domination Timer prototype - a timer in the style of a chess clock for Airsoft / Paintball with firmware for 2 teams - BLUE and RED, which play against each other and try to occupy a point and then keep it for the longest time possible.

A player of a team occupies a point by placing his RFID card to the RFID reader, which beeps to announce the change on the point, lights up the team's LED and starts adding time to the team in seconds. If the card is placed by a member of the second team, the time of the first team will stop at the current value and the time of the second team will start counting + the color of the active team will also change on the LED point.

The maximum time for listing on the LCD character display is 99 hours, 59 minutes, 59 seconds. Stopwatches are thus also suitable for several-day events such as LARP, MilSim. Suitable especially for Capture The Hill / DOMINATION game mode. I am also supplying the machine code for the Domination Timer, which is already loaded into the unit. This will make it possible to clone the program to any number of other devices that you can create, and they will respond to identical RFID cards with identical configuration, so it is possible to create several Domination Timerpoints in your gaming area that will work independently of each other.

Together with the Domination Timer, RFID cards are also supplied, 7x for each team, 2x for the Referee and 1x for the Eraser. With his card, the referee can stop the game and neutralize the point (the current times remain written on the display), the counting is reactivated by applying the team member's card. If Eraser applies his RFID card, the point is reset to 00 h, 00 min, 00 sec.

The hardware is mounted on a PCB (104x101 mm), while the main components (Arduino Nano, LCD display and RFID reader) are mounted on pin strips. Thanks to this, the components can be replaced with new ones in the event of a malfunction without the need for soldering the components, they are simply pulled out of the slot after unscrewing the component from the spacers. The DPS also has the option of adding two pullup 10K resistors for the I2C bus SDA and SCL signals.

System power via microUSB, average consumption approx. 50 mA at 5V power supply. The system can run for about 36 to 40 hours on a 2000 mAh power bank (depending on whether the LED is active - higher consumption, etc.). The device is plug n' play, just connect the power supply and operate.

I do not offer DPS design or source code for this product. The DPS has mounting holes in the corners, which are primarily used for distance posts, but adapters (extendre) can also be used for the possibility of mounting on the wall, etc. The device must be operated indoors, the device is not supplied with a box, the device is neither waterproof nor waterproof. Domination Timer has acrylic front plate that is transparent, there are used extra pillars to hold it on PCB.
