本文將使用TinkerCAD Circuits來示範光感測器(Photoresistor)的應用：「光控自走車」。讀者也可參考本部落格的文章mBlock 單元十五：追光自走車。
This tutorial uses the light brightness to control a car. This car could be implemented by a Arduino with photoresistors. Before assembling the hardware, the simulation could be done with TinkerCAD circuits. The reader could read this article:"mBlock Unit 15: Light-Tracking Car" later.

材料(Materials)：
1. Arduino UNO R3 板子 x 1
