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.

THIS CODE WILL PROVIDE A DEMO USE OF THE HC-SR04 CONNECTED TO AN ARDUINO NANO (ATmega328p) THINGS YOU NEED FOR THIS DEMO: 1.) Install Arduino IDE 2.) Install CH340 Driver (Google how to install CH340 ...

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, ...
