Using an if/else statement, the variable value is compared to the threshold. If the variable is above the threshold (its bright), turn the LED off. If the variable is below the threshold (its dark), turn the LED on.Open the Serial Monitor in Arduino. The value of the photoresistor should be printed every so often. When the photoresistor value drops below the threshold, the LED should turn on (you can cover the photoresistor with your finger for testing).NEW IDEASLIGHT LEVELS: If the room you are in is very bright or dark, you may have to change the value of thethresholdvariable in the code to make your night-light turn on and off. See the Troubleshooting section for instructions.PROGRAM OVERVIEW1 Store the light level in the variablephotoresistor .2 If the value of thephotoresistoris above thethreshold(its bright), turn the LED off.3 Otherwise, the value of thephotoresistoris below thethreshold(its dark), turn the LED on.28 : circuit 1c'
