当环境光线变亮时，又自动关闭灯带。 连接 Arduino ↔ LDR 分压 ↔ 继电器模块 ↔ 12V 灯带。 热熔胶枪（可选） 用于固定 LDR 位置或整理线材，提升结构可靠性。 A0 点的电压随光照变化而变化，Arduino 通过 analogRead(A0) 读到 0–1023 之间的数值，即可反映当前亮度。 为了安全与隔离，LED 灯带不直接由 Arduino 供电，而是： 灯带的 正极( ...

Analog-to-digital converters, or ADCs, are somewhat monolithic devices for most users, a black box that you ask nicely for the value on its input, and receive a number in return. For most readers, ...

Canadian electronics geek and nascent YouTuber [Technoyaki] wanted to measure 20 volt signals on his Arduino. One might typically use a voltage divider to knock them down to the 5 volt range of the ...

The project illustrates the driving of analog meters using PWM outputs from Arduino as well as the LCD Smartie program. A small current is typically required by meters to operate wherein a typical ...

对于一个基于ADC的112-Gbps LR SerDes PHY，带有DSP的PAM-4对于克服串扰和信号丢失至关重要。要解决串扰和损耗，每个符号必须传输多于一个比特位。采用PAM-4，眼图中有三只眼睛而不是NRZ的一只眼睛，信噪比因此降低了9 dB，要解决此问题，需采用最佳的ADC和DSP，而且 ...
