Carlo Gavazzi's new ultrasonic sensors offer flexibility, rugged durability, and increased accuracy, along with a compact design, to take on harsh environments. The UA12, UA18, and UA30 (see ...

The movements of four dancers onstage cascade from LED lights on their costumes up ... veteran talent-show judge then pressed his Golden Buzzer, raining gold confetti over the proud performers.

Basically, this program enables the Arduino UNO R4 to connect to an existing WiFi network, so it can send an SMS alert via API when the flame sensor or smoke sensors detects fire and smoke. At the ...

This project uses an HC-SR04 ultrasonic sensor and Arduino UNO to measure the distance of objects in both centimeters and inches. The measured data is displayed on an I2C LCD. The project was ...
