In LDR, how to change 10k to 330ohms
@soups2012 check on the colour of resistor …
A sequence of different colour represent different set of resistance…

Tell me is matter is solved or not

Value x Multiplier = Resistance
3.3 x 100 = 330Ω
As an example of this rule of thumb is, consider this arrangment of resistors:
To analyze it, take the two 10k’s in parallel first – they combine to make a 5k. Now you’ve got two 5k’s in parallel, for a total of 2.5k ohms. Simple!
Here’s another example, which makes the rule of thumb seem even more clever:
Instead of reaching for your calculator, think of the 5k as two 10k’s in parallel. Now you’ve got three 10k’s in parallel, for a total of 3.3k.

I hope your problem will be solved.
thanks!
it’s pretty easy to change 10k to 330 ohms.
10k ohms color code is brown-black-orange-gold (biscuit color resistor)
330 ohms color code is orange- orange-brown gold (blue color resistor)
the LDR & 330 ohm should not touch each other.
firstly, connect LDR between 3.3 & A0 pin
next, connect 330 ohms resistor between A0 & ground
