In the setup function of Arduino how do I average 50 readings to determine ambient light level and save the average voltage in the variable Vref?
You can use a FOR loop to loop 50 times, add the reading to a variable and then divide by 50 after the loop completes to determine the average. Make sure that you use a variable type large enough to keep the total. Keep in mind that unless you put a delay in the loop the 50 readings will be taken very fast and will probably vary little. You need to consider what a reasonable time to measure to determine what a good average would be, and then add a delay to give you the right period to take the average over. For example, if you want to take the average over 5 minutes (300 seconds), you would need to add a delay(6000) 6 seconds) to stretch it over the measurement time. Keep in mind that your main program loop won't start until the setup process is complete, so in this example the setup process will take five minutes.

How is the Arduino board powered?
Most arduino models (including the Arduino Deumillanove and the older Arduino NG), can be powered with either a USB cable connected to a computer or with a 9v battery that is wired up to a 2.1mm barrel-tp male plug.
How do you return current time in arduino nano...?
The current time in Arduino Nano can be done by resetting the software. This will allow the system to run on the correct time. This may be done at home or by and IT professional.

How can you create a circuit that counts the number of times a switch is closed?
To create a circuit that counts the number of times a switch is closed, you can use a microcontroller (like an Arduino) or a digital counter IC (like the 74HC4017). Connect the switch to a digital input pin (for the microcontroller) or to the clock input of the counter IC. Each time the switch is closed, the microcontroller can increment a variable, or the counter IC will advance its count. Finally, display the count on an LED display or through a serial monitor for the microcontroller setup.
