This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

So I removed this servo and IR sensors and use 3 ultrasonic sensors. With ultrasonic sensors, you can measure distance and use that information to navigate and follow a human target. Here’s a general ...

Ultrasonic sensor powered by Arduino UNO The servos should not be powered by the Arduino directly due to insufficient current supply, which could damage the voltage regulator. Instead, an external ...

Smart Blind Stick using Arduino Circuit Diagram The below circuit diagram shows the complete hardware wiring setup of the Arduino-based Smart Walking Stick for the Blind people, detailing how the ...

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 ...

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.

In previous times, the task of cutting or mowing grass required a significant amount of time and exertion. The introduction of a novel breed of mowing equipment significantly facilitated the task, ...
