user11284: I used simulator 123d.circuits.io to create simulation of basic circuit with LDR: LDR is connected to 5V and via 10K resistor to GND. Wire between LDR and resistor is connected to analog pin where I read ADC values and display them using serial monitor. This works fine. But I would like to how to change lighting level of LDR in simulation because this way LDR shows still the same value. I tried putting LED or light bulb near LDR but it doesn't seem to have any influence. Any ideas?

user11284: Ok, so I found it myself. You can click on LDR during simulation and bar to adjust lighting appears above it.
