do nothing and wait for btnSELECT to reset the game
P0.secondsRun += (p1.secondsRun + p2.secondsRun) Lcd.print(menuPlayer->menuText + playerMins) PlayerMins = String(menuPlayer->minutes) set pointer to player 2 as player to change time forĭelay(500) // delay required otherwise the button fires repeatedly set pointer to player 1 as player to change time for number of seconds for the MM:SS display Return minsAllowed * 60 - secondsRunSoFar number of seconds remaining on the player's clock We make this the 1st option for speed reasons since it will be the most likely result we add approx 50 to those values and check to see if we are close buttons when read are centered at these values: 0, 144, 329, 504, 741 define some values used by the panel and buttonsĪdc_key_in = analogRead(0) // read the value from the sensor
MULTIPLE COUNTDOWN TIMERS IN ARDUINO CODE HOW TO
This code is from a sample library on how to use the LCD keypad The menu display, used to set the minutes available for The main display, which shows the active player and the This program uses the LCD panel and keypad to create a Press SET button to set the time, it will ask you to set the minutes first: Press INC / DEC buttons to set your desire minute, in this example we have set minutes to 10.
Chess clock using the LiquidCrystal library Setting countdown timer to 2 hours and 10 minutes as an example: Power the circuit on it will display 00:01:00 (HH:MM:SS). It works as expected, but I don't know whether this is good idiomatic C++/Arduino code or if I could be using better data structures, standard library functions, etc and would be grateful for any tips. I've written this code for a countdown timer and a simple menu to set the time available to each player, using button handling code from here. I'm very new to C++ and Arduino, with a background in Python.
