In this video I build a reverse coupling and use it to try and solve the drone's issues. In this series, I will be building a single propeller spherical drone which will be controlled via an Arduino.

[导读]本项目在RT-Thread RT-Spark开发板(STM32F407)上实现了红外距离传感器。红外LED发射红外光，光电二极管检测来自附近物体反射回来的光线强度。ADC读取电压值，固件将其映射为RGB LED颜色——远距离时为绿色，非常接近时为白色。 LED颜色与距离范围对应如下：绿色表示检测到的物体在20厘米以外;蓝色表示物体在16至20厘米之间;黄色表示12至16厘米之间;红色表示8 ...
