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( ...

The Arduino UNO Q is more than just the next generation of the flexible UNO platform; it’s a new development paradigm.

I had cause to have a closer look at some Arduino inputs – it is that fascinating weather station again. It transpires that some Arduino inputs are better at tolerating slowly-changing inputs than ...

There is a boring part of every computer introduction class that shows how a computer is made up of input, output, and processing. Maybe it wouldn’t be so boring if the input device was a nunchuck.

The long-awaited Arduino Due just hit the market, replacing the 8-bit, 16MHz brain of the popular Uno microcontroller prototyping platform with a 32-bit, 84MHz processor, while augmenting inputs and ...

If you are looking for a project to keep you busy this weekend you might be interested in a new MIDI fader unit which is being created using a little 3D printing and Arduino programming. Check out the ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...

The EasyNixie Arduino compatible low-voltage Nixie Tube driver module has emerged as a versatile and user-friendly tool for hobbyists and professionals alike. This module, designed with a focus on ...

Spark Devices wants the inclusion of WiFi in devices to be a matter of when, not if -- and if its new Spark Core gets to market as planned, tinkerers might never have a moment of doubt. The tiny board ...
