Here, 1.02 thousand = 1023

Below respond should clear the rest of the doubt.

Meaning of 1.02 thousand while making light_monitor system

Explanation regarding the value “1.02”- The A0 point is the analog point and it takes in the value of voltage between 0 to 1.The taken value say 0.576V is converted to a binary number of 10 bits,by the in built ADC converter.So each value read by A0 pin is given by 10 bit binary number whose decimal equivalent ranges from 0 to 2^10-1(this decimal equiv. is shown in the output table). Now in our case at bright light LDR,resistance lowers down and it gives less drop so A0 pin gets high value.For…
