This is a very small light sensor. A photo resistor (also known as a photodector, or photocell) changes resistance depending on the amount of light it is exposed to.
This RTR robot uses custom length sides and 10 inch tires. We have included everything to make it ready to run including batteries, controllers, chargers, etc. It has been fitted with a custom top cover.
100 pack of black UV resistant nylon with flexible tape section, pull tight and does not come undone. Length 8 inches.
