描述

几天前，我从童年时代发现了一辆漂亮的遥控车，但它的遥控器坏了，所以我想为什么不把这辆车改装成高速 Arduino 遥控车。

所以现在就在这里，我已经把它变成了一辆高速 Arduino 遥控车，今天我将与你分享我是如何做到的。我用于这个项目的应用程序可以从这里下载。

高速 Arduino 遥控车的功能

这款高速 Arduino 遥控车的功能如下

  • 前灯
  • 背光灯
  • 中心的 RGB 灯会让它看起来不错
  • 喇叭
  • 全方位旋转
  • 速度控制

所需组件

高速 Arduino 遥控车所需的组件如下

  • 带电机的旧车
  • 阿杜诺
  • HC-05 或 HC-06 蓝牙模块
  • L298N电机驱动器
  • 蜂鸣器
  • RGB LED
  • 2 个红色 LED
  • 2 个白色 LED
  • 2 X 3.7V 可充电电池
  • 9V电池
  • 7 X 220 欧姆电阻

硬件

我使用了两个 3.7V 的可充电电池来运行这些电机。这些电池可以反复使用，也可以快速运行电机。

将顶部车身安装在其上后，这辆车看起来就像一辆原始的兰博基尼。中间连接的RGB让它看起来更漂亮，它的高速使它可以与市场上的遥控车竞争。
