I offer firmware for Domination Timer (DOMINATOR) - equipment - stopwatch for extreme sports such as Airsoft, Paintball, Nerf Wars, etc. Created for 2 teams - RED and GREEN. The stopwatch works and is tuned. The counter works for hours, minutes and seconds.
Functionality principle:
The stopwatch consists of an Arduino Uno / Nano / Mega microcontroller, a 16x2 / 20x4 LCD character display with an I2C converter and 4 buttons for digital input
There are 4 buttons in the system, 2 of which are for teams that press their team's button if they occupy this point.
The team that pressed the button starts to add time on the display.
The current team (whose time is counted) is also announced by the LED diode on the control panel.
If the point is occupied by the second team, the time of the first team stops and starts to be added to this team.
The buttons are connected as INPUT_PULLUP, so they switch to ground and use an internal 5V Arduino resistor.
If the button is pressed by the referee, the game stops until the button of one of the teams is pressed.
If your button is pressed by the eraser, the game ends and the times are restarted - DOMINATOR ready for a new game.
Maximum time range: 99 hours, 59 minutes, 59 seconds. DOMINATOR is therefore also suitable for several day events.
The logic of the system works with an immediate response to a button press (it is not possible to configure the length of its press in this version)
Project hardware:
Arduino Uno / Nano
LCD 20x4 / 16x2 with I2C converter
4x switch buttons
2x LED diodes - indicator of the team whose time is running out
Buzzer (optional)
I supply:
Wiring diagram (compatible for all mentioned microcontrollers and a separate AtMega328P chip)
Machine code for microcontroller (.hex)
The firmware can be cloned to any number of DOMINATOR points that you can include in the game. The firmware is supplied in .hex format and can be uploaded to the Arduino / AtMega chip via AVRDUDE / XLoader graphics superstructure.
