i have problem programming my Arduino Uno for my DSLR-slider project.
I have to accomplish this function:
pushbutton starts the function
output A (motor) is active for time 1
after time 1, there is a delay time 2
after time 2, output B (DSLR) is active for time 3
after time 3, there is a delay time 4 and the program starts to repeat
|-------------|------------------|-----------------------|--------------------|-------------------->
Output A delay 1 Output B delay 2 Output A.......
I´ve justed started working with Arduino, so I tried the delay()-function. But it didn´t worked well, because I couldn´t use my pushbuttons because of the delay-functions...
I´ve already looked up the BlinkWithoutDelay-example and some of the timers in the Libraries, but none of them seemed easy or suitable...
I don't know why you think otherwise, but the blink without delay example seems to me to be a perfect starting point for your project.
Other useful search terms might be "state machine"

In your description, you didn't mention anything about the behaviour if the button is pressed before the cycle is complete. What do you intend to happen?
It´s about the mainswitch to pause or cancel the program. There are also other programparts, which have to work and shouldn´t be stopped. Like the LCD-display, which is showing the remaining time. With the delay()-function this wouldn´t work...
I´ve tried the BlinkWithoutDelay-example. But I didn´t understand how to use it with 4 different timers and how to setup the time of the output-ON and the time between the output-ON. The example is just 1 second on and 1 second off. But for example I would need: 1 second on, 3 seconds off.
