Arduino Sketch

Circuit specifics Setup: 3 LEDs (1 green 530nm, 1 amber 590nm, 1 red 625nm) Cree xLamp XP-E2 Color High Power LED Star LEDS ([login to view URL]) 1 Driver – MicroPuck Boost DC LED Driver [login to view URL] ( I am not sure if this is completely necessary but was told by the LED dealer it was, in order to prevent damage to the LEDs, even though they will only be on for a short period of time) 3 push buttons 1 Arduino Uno ( I am open to not using an Arduino, but the ability to modify the circuit easily to change the duration the LED’s are on, is a priority) 4 AA NiMH batteries ( I am open to changing this if it increases LED intensity and/or battery life, however, it must be a standard battery, AA, 9V, i.e using more than 4 AA batteries) (Also, after further consideration, I would be open to running an external power source to the board, for extended proof of concept trials, if using battery supply doesn’t give me extended use. However, it must be able to run on batteries alone) Goal: The purpose of this sketch is a proof of concept and will not be the final configuration, should I proceed with this. However, the priority is a reliable sketch with maximum battery life and maximum brightness when the LEDs are activated. Sketch background: All three push buttons will be pressed one time during each sketch/cycle, but not always in the same order. It is important that the LEDs be turned on in the same order every cycle. First the green, then the amber, and finally, the red LED. It is important that a push button can remain depressed but only turn on the LED one time while also not consuming any additional power. (I am not sure if this is standard or something needed to be known) Also, it needs to be possible that a push button can be depressed while the next push button gets depressed, and not interfere with the second push button turning on the next LED in the progression. It is also a priority that the LEDs be as bright as possible when turned on during the cycle. With this sketch, ideally, I would like to get at least a week if not more days before the batteries need to be replaced. In a typical day, the sketch would run anywhere from 2-5 times in a day. I mention this because it seems, from my understanding, that while on standby, the arduino will draw power from the batteries while on standby. I am not sure if this is true but if so, I would like to be able to ensure this would run for a minimum of a week before battery depletion. If this means adding additional AA batteries, I would be willing to do so. Sketch: 1st push button is depressed = turns on green LED for 1 second or until ; 2nd push button is depressed = turns off the green LED (if still on) and instantly turns on the amber LED for 1 second or until; 3rd push button is depressed = turns off the amber LED and instantly turns on the red LED for 1 second (Note: I want the ability to modify the sketch to be able to increase or decrease the time the LEDs are on during the cycle, if 1 second is insuffient) The sketch/cycle is over one the 3rd push button is depressed/activation of the red LED. (Note: the 3rd push button may be continually depressed but I would like this to not affect the battery life, if possible)
