您可以控制亮度和颜色的每个LED的独立。 该LED灯条由串联连接的WS2812B LED制成。这些LED的LED内建有一个IC。这允许通过单线接口进行通信。这意味着您仅需使用Arduino的一个数字引脚即可控制许多LED。 在下图中,您可以看到LED内的芯片。LED是RGB LED,工作原理是这样的: 这种非常灵活,可以切成您想要的任何长度。如...
Note that the LED will only stay on while the button is depressed, and will shut off when you release it. Here’s the full source code:int btstate = 0; void setup() { pinMode(13, OUTPUT); pinMode(11, INPUT); } void loop() { btstate = digitalRead(11); if (btstate == HIGH...
多彩LED灯环(16颗灯) 1块 锂电池(150mAh) 1块 USB充电器 1个 导线(3个颜色) 3根 材料 除了以上产品,您还需要以下辅助材料: 一个固体导电无涂层的金属吊坠,直径大约2英寸或更大,带有允许光线通过的镂空。我用了hildie & jo的这个: 烙铁及焊料

An Arduino Pro (via common emitter 2n2222 on/off circuits) provides some digital love to the 18 LED columns and is connected to a Velleman Sound-to-light kit which modulates the brightness of the whole visor based on da funk. Two pots are also wired to provide sensitivity and pattern ...
TheresistorR1 limits the current flowing through the LED and prevents damage when running on voltages higher than 3.7V. When the left hand side of the capacitor transitions from 0v - 2V the right hand side should show a 2V transition but starting at 1.3V and rising to 3.3V. I measured...
