The authors propose a radar made with the ultrasonic sensor type HC - SR04, developed for Arduino. The novelty added by this paper is the development of specific libraries aiming to interface the ...

The smart water controller for metro water supply lines described in this work makes use of a relay, an ultrasonic sensor, a flow sensor, a solenoid valve, GPS, and GSM. The planned system is intended ...

This Arduino code utilizes an ultrasonic sensor to measure distances. When an object is detected within a fix distance , the connected motors trigger a sequence: move backward, turn right, turn left, ...

This Arduino sketch converts an original Amiga 500 keyboard into a USB HID, allowing it to function as a modern USB keyboard. The sketch reads the Amiga 500 keyboard signals and translates them into ...
