Sample code for SR04 ultrasonic ranging sensor. 注意：确保设备在3.3伏而不是5伏的电压下使用。Duo GPIO不能在5伏电平下使用。 NOTE: Ensure the device is capable of being driven at 3.3v NOT 5v. The Duo GPIO cannot be used at 5v.

Some of the best hacks are the ones which seem perfectly obvious in hindsight; a solution to the problem that’s so elegant, you wonder how it never occurred to you before. Of course we also love the ...

Abstract: The automation of height-increasing bridges during floating events is a crucial engineering challenge in areas prone to flooding or water surges. It proposes a solution to adjust the bridge ...

The HC-SR04 ultrasonic range sensor is a pretty cool pre-wired module that you actually enjoy using when you start playing with electronics, microcontrollers, and robotics. As you might have noticed, ...
