[Thomas] wanted to play around with a few high-power LEDs and a RaspberryPi. LED controllers usually require some form of PWM to change the brightness of a LED, and unfortunately the Pi only has one ...

PWM (Pulse Width Modulation) is a method of adjusting output by changing the width of pulses. For example, when blinking an LED, if you make the time it stays lit longer, it becomes brighter; if you ...

注意 / Note: 新版树莓派系统（Raspberry Pi OS Bookworm 或更新版本）已内置pigpio库，可以跳过这一步。 If you are using newer Raspberry Pi OS versions (Bookworm or later), pigpio is already pre-installed and you can skip this step.

You've managed to turn a motor ON/OFF with a Raspberry Pi, but being limited to just two choices—'always running at full power' or 'stopped'—doesn't allow for the delicate movements required for ...

A documented Raspberry Pi 5 cooling mod using a Noctua NF-A4x10 5V PWM fan, a custom JST-SH 4-pin to Noctua PWM adapter cable, and a KKSB Raspberry Pi 5 + M.2 NVMe HAT case. This project solves a ...

Imagine being able to check up on your Raspberry Pi from anywhere in the world using a simple web interface. With PiCockpit, you can monitor your Raspberry Pi, control GPIO pins and run health tests.

At first glance, using a microcontroller for a simple fancy light project is overkill. However, the existing design can be modified later without additional hardware. Often a few extra code lines will ...

Makers, developers and hobbyists that enjoy using the Raspberry Pi mini PC to build projects may be interested in a new Raspberry Pi servo controller that is capable of controlling up to 3 servos, 2 ...
