Thanks in advance for any help. const long Minutes = 1; const long Interval = (Minutes * 60 * 1000); If later you want to do 7 minutes or something, it's easy to change See full list on deepbluembedded. delay(60UL * 60UL * 1000UL); //60 minutes each of 60 seconds each of 1000 milliseconds all unsigned longs As long as you don't want anything else to happen during the hour There are better ways as in the BlinkWithoutDelay example in the IDE. Looks like the power supply can only put out 1A (I now see that the valve says it requires 2A, however, it still fires just fine when connected directly to the power supply, so I'm thinking this is not the issue). 15 minutes is 900-seconds and delay(900000ul) would give you a 15-min delay. If you really want it to poll every 1 minute, or your download has the possibility of taking longer (such as a slower connection or larger file), then use the interrupt. case 2: if button2 = HIGH; runTimer 10; // Run timer for 10 /* Delay in microseconds. But i need help with a Arduino - delay function - The way the delay() function works is pretty simple. When you do delay(1000) your Arduino stops on that line for 1 second. This tutorial is a simple sketch and circuit to show how this is done. What i'm doing is , I'm using an infrared sensor and counting the element passing through that sensor for a minute/or any time. When you press the button to start the race, the Arduino does some subtraction to figure out the time, and when a light gate is tripped at the finish, the time and place are printed on the serial monitor. Unsigned longs on the arduino can reach from 0 to 4,294,967,295. Take the number of minutes, multiply it by 60 to get the number of seconds, and then multiply it by 1000 to get the number of milliseconds. Make an Arduino delay for 1 minute.
