Photosensitive Resistance Kit (Pack of 30)

The range of resistance values in this pack is perfect for prototyping different light-sensing circuits. I've already used half of them to adjust sensitivity on a couple of Arduino projects, and they respond exactly as expected.

These are great for my microcontroller light-sensing experiments, and having 30 of them means I can mess up a few without worrying. The smaller 5mm ones are noticeably more sensitive than the larger discs.

The variety of resistance values in this pack is perfect for testing different light thresholds in my sensor experiments, and all 30 arrived intact and working. My photoresistor circuit responded exactly as expected when I tested it under a desk lamp.
