The DIY (Do It Yourself) Kit for Children Age 4 to 12 Years Old

If you have trouble playing the video above, you may access the video from here.

Photoresistors, also known as light-dependent resistors (LDR), are light-sensitive devices most often used to indicate the presence or absence of light or to measure the light intensity. In this kit, you will learn how to connect an LDR sensor with a DC motor to create a light-dependent fan! If the light sensor is in a dark room, the fan will switch off automatically, and if the room is bright, the fan will turn off itself.

So what are you waiting for? Get this for your kid! This DIY kit is simple enough to be built by 4 years old children, with parent's help. And children 6 years old and above can build it by themself!
