Our kit includes the Maker Uno RP2040 itself, four Grove to jumper cables, a USB-A to USB-C cable, a soil moisture sensor with one Grove cable, an HC-SR04 ultrasonic sensor with a Grove cable, a SG90 ...

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 ...

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 ...

The design of a “third eye for the blind,” which employs ultrasonic waves to detect surrounding obstructions and notify users with a buzzer sound or vibration, is made feasible by the collaboration of ...

Ultrasonic Sensor Measurement: The HC-SR04 ultrasonic sensor measures the distance to an object by emitting a sound wave and measuring the time it takes for the echo to return. The sensor is connected ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

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 ...

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 ...
