I bet you wouldn’t have guessed this Colorful Carousel was made entirely using PCBs

Christmas star built on 18 LED diodes.

Here is another project with LEDs

Enjoy another project with LEDs

This project features a custom 3D-printed 'Mortal Kombat' trophy shell paired with a basic NE555 timer circuit in 'astable mode'

This small 20W RGB video light can be fully 3D printed and is very simple to operate. You can switch on the light by pressing the button on the side once. By rotating the encoder, we can cycle through the hue value. After pushing the encoder, we can switch to the brightness control mode. We can adjust the brightness of the LED by rotating the encoder. If we push the encoder button again, we can switch back to the hue control mode. It's a one-knob operation.

Wire up your RGBW LED strip to Wi‑Fi with ESPHome! This 12 V controller drives four PWM channels—R, G, B, and W—using a simple ESP8266 board. Ideal for Home Assistant, perfect for ambient lighting, and totally local.

This is a 10 channel spectrum analyzer with a antique look that can easily be modified to fit a steampunk NIXIE theme.

This project delivers crisp and reliable stair lighting with motion-triggered LEDs – no fading, no delay. Designed to handle up to 16 steps, it reacts instantly to movement using PIR sensors and can be configured for night-only use, sensor types, and output timing. Simple, effective, and 100 % standalone.

Due to Christmas celebrations elecrow make an offer for PCB with Christmas theme

Foldable Lamp Box - Night Light - reacts to sound and has adjustable brightness, USB port for charging, runs 24h on Battery - ATtiny85 processor - 25x WS2812 leds

In this tutorial I am going to create a chaser circuit that can drive 20 or more LEDs using 555 timer IC and CD4017 decade counter.

This is a visually impressive hourglass simulation project, and despite its simplicity, there are many possibilities for modifying most parameters.

This is a light bulb indicator kit that blinks with music.

You can use up to 24 white LEDs.

In this tutorial, I am going to show you guys how to design this "Transformers PCB Badge" and how to solder the components to it.
