This is a custom version of the Hunter game with 10 LED and LCD display to show the score, followed by various sound effects.

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

Small night lamp with NE555 and one LED,

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.

Christmas decoration built on 18 LED diodes.

Bring your staircase to life! This motion-controlled PCB lights up to 16 steps with smooth fade-in and fade-out animations. Configure sensor type, delays, night-only mode, and animation behavior – no app or cloud needed. Fully documented with schematic, layout, and ready-to-use firmware.

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

These candles flicker like a real candles and can be activated with an actual flame

Christmas star built on 18 LED diodes.

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.

ESP-LED-03 is an Audio-Reactive WLED Controller based on ESP32-S3 Supermini. It supports 5-24V Led Strips, has wifi, bluetooth, IR control, Light sensor, microphone for audio-reactive (optional) and more!

The edges of the acrylic are illuminated to make letters and pictures stand out.

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.
