DIY KIT 21- How to a make a photoresistor based dark sensor
I have written several posts similar to this one before. This experiment is again about a dark sensor based on LDR or photoresistor. There are a few components and basic soldering experience should be enough to build this up. It is a good and easy kit for electronics beginners.
You can see all the assembly steps below. All the images are available on Flickr also.
