In September 2024, I DIYed an RGB LED volume meter using the ATMEGA328P to collect analog signals and drive the WS2812. The strip is 1 meter long with a total of 60 LEDs, super cool and super fun so it’s basically online 24 hours a day. Later, while browsing forums, many experts were talking about … Read more
In the previous experiment, we learned about the principle of the running light—multiple LEDs lighting up and turning off in sequence. In this experiment, we will learn how to implement a breathing light using Arduino. Unlike the running light, the breathing light achieves a “breathing” display effect by gradually adjusting the brightness of the LED.1. … Read more
How did I come up with the idea of making a music box? With International Women’s Day approaching, QiuQiu said he wanted to give me a gift, and also a big present. QiuQiu made a small bag by himself and asked me to buy some chocolate online (he promised to pay with his pocket money … Read more
This project uses the ESP8266 chip, which can connect via Wi-Fi, allowing you to remotely control the color of the RGB LED mood light using a smartphone or other terminal devices with a browser. It is a DIY project that costs less than $10. Before starting, we need to understand information related to the ESP8266 … Read more
