void blink(){ state++; } This code works as follows: When there’s no interruption to the program, the code keeps running and the D13-LED stays in OFF status. But when there’s an interruption (i.e., ...

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy ...

[electron_plumber] made an LED that can be blown out like a candle, and amazingly it requires no added sensors. The project uses an Arduino to demonstrate turning a tiny LED on and off in ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

Aiming at vibration-based equipment condition monitoring, Analog Devices has introduced a kit for hardware, software and algorithm development that will interface with data analysis tools including ...

(Source: Arduino) The UNO R4 WiFi version comes with an Espressif ESP32-S3 module for Wi-Fi and Bluetooth Low Energy connectivity. The bright 12×8 red LED matrix is ideal for creative projects using ...

The Vocalzoom sensor can detect vibration frequencies up to 6kHz as well as very slow vibration processes in an ultra-low frequency range. In addition, the measurement method is insensitive to ambient ...
