What your child needs to bring to camp will vary on the camp type, length of stay and your child's age. The needs for overnight camp are also more extensive than those for day camp, but here's a helpful general guide to get you started.
The camp you and your child choose should be able to also provide you with a packing list of suggested items, so be sure to ask them. Detailed printable packing lists are available here:
Remember to label your camper's belongings. If you don't, you might be amazed at what your child brings home (or leaves behind).

Sturdy footwear (running shoes, sandals, at least one pair that's waterproof)
Toiletries
Bedding and towels
Flashlight

Optional items such as: musical instruments, camera, writing supplies (pen, paper, stamped envelopes), books, games, small backpack (maybe even a small surprise treat!)
What to leave at home
Electronic games and personal listening devices
