Light intensity project

Hey!
can somebody please tell me what are the units of the light intensity project?
As per my knowledge the units should be in mega or kilo ohms. please verify!

Hi @prabhbirkaurrandhawa,
The reading is the ADC(Analog to digital converter) Value,just a number between 0 and 1023 that is proportional to the voltage present on pin A0 between 0-1V, 0 denoting 0 V, and 1023 denoting 1V. Check this out to learn more about the ADC.

Yes, it would be a proportional to the resistance as per ohm’s law, V = I*R.

It is the value between 0 to 1023. The voltage present on A0 pin is between 0V - 1V. So 0 denotes ) volt and 1023 denotes 1V.

It is denoted in volts and the value is from 0 to 1023 V. In the serial monitor you can find the value ranging from 0 to 1023.
