I would probably choose C1=2.2μF (or use a pair of 1μF caps in parallel).

To turn on an LED for 1 second, you will need to use a microcontroller or Arduino board. Connect the positive leg of the LED to a digital pin on the board and the negative leg to ground. Then, use the digitalWrite() function to set the digital pin to HIGH, which will turn on the LED. To ensure it stays on for 1 second, use the delay() function to pause the code for 1000 milliseconds.
To turn off an LED for 1 second, you will follow the same steps as turning it on. However, instead of setting the digital pin to HIGH, you will set it to LOW, which will turn off the LED. Again, use the delay() function to pause the code for 1000 milliseconds to keep the LED off for 1 second.
To make an LED blink continuously for 1 second, you will need to use a loop in your code. Within the loop, use the digitalWrite() function to turn on the LED for 1 second, followed by a delay() of 1000 milliseconds to turn it off for 1 second. This will create a continuous blinking effect.
Yes, you can adjust the time the LED stays on and off by changing the value in the delay() function. The value is in milliseconds, so for example, if you want the LED to stay on for 500 milliseconds and off for 500 milliseconds, you would use delay(500) in your code.
Yes, as long as the microcontroller or board has digital pins and the ability to run code, you can use it to control the LED. Each microcontroller may have a slightly different code, but the basic principle of using digitalWrite() and delay() functions to turn the LED on and off will remain the same.
