描述

步骤1:零件清单

R1 = 10至220Ω½W取决于首选的LED亮度

R2,R3 = 10ΚΩ¼W

Arduino Uno

霍尔传感器

7805 5V稳压器TO-220

C1,C2 = 220 uf

7段LED显示屏(共阳极)

9-12 v电池(否则连接设备

连接电线,通用PCB。

步骤2:工作原理

指示器

主要工作原理基于AVR Arduino UNO。

读取两个霍尔传感器和空档开关的信号,并将当前档位输出到7段LED指示器,通过

在最大输出功率下,传感器和传感器产生的热量很大。或出于这个原因,我们将其直接安装在接地层上以实现最大的散热。

第5步:安装

将所有电路组装在一起后,电路便可以正常工作并可以安装在摩托车上了。

在我的照片中,我将这种指示器用于基于杜克自行车发动机的汽车

因此自行车的安装技术类似。..

注意:齿轮机构与自行车相同。
