前言遥控器种类主要‌按传输技术分为红外遥控器、无线电遥控器、蓝牙遥控器、WiFi 遥控器等‌,同时也可按应用场景、通道数、编码方式等维度进行分类。下图是一款红外遥控器,其中的功能有:开启,关闭,减亮,加亮,2分,5分,10分,分可以理解成档位。
步进电机是一种无刷同步电机,它将整个旋转分成若干步。每个步进电机都有一些固定的步进角度,电机以这个角度旋转。在这篇文章中,我将向你展示如何使用两种不同的驱动器将步进电机与8051系统连接: L293D和ULN 2003。此外,这里还解释了使用8051单片机控制 ...
The L293D datasheet specifies that this device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads ...
Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...
