do i really need arduino or any programming?
can i just connect the battery ,the light sensor and the bulb in a simple circuit?
if you use a light dependent resistor you need to make sure that it can take the current
What "the current" are you talking about?
The current that it will pass in what ever circuit arrangement you end up with.
When was the last time you have used a photoresistor that cannot take the current going through it?
Back in 1965,
have you never used these?
