What better way for a father and son to spend the Thanksgiving weekend together than to build a robot out of a tin can and an Arduino. As far as robots go, this little autonomous aluminum can seeks out light and moves in the direction of it. The creator cleverly refers to this as a “flashlight leash.”
With an Arduino, a light sensor and a lower power DC motor, making your own light-seeking robot shouldn’t be too difficult of a task. With your kid helping you, who knows what you could accomplish?
