This Arduino project controls a servo motor based on distance measured by an HC-SR04 ultrasonic sensor, ... HC-SR04 Ultrasonic Sensor: VCC pin → 5V on Arduino GND pin → GND on Arduino Trigger pin → ...

One way to accomplish this involves four HC-SR04 ultrasonic sensor units that transmit data through an Arduino into a Linux computer. The end result is a virtual touchscreen that can be made at home.

Buy arduino, buy sound shield, buy distance sensor shield, plug into each other, burn example code, stuff components inside box. Not only is this not a hack but he might as well have just bought a ...

This project presents an experimental evaluation of the HC-SR04 ultrasonic sensor connected to an Arduino Uno microcontroller. The focus is on measuring the sensor’s performance in terms of accuracy, ...

In this mode, you can interface the HC-SR04 ultrasonic ping sensor with a servo motor and the main board (Only some reward tiers include the extra servo motor PCB and servo motor kit).

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...
