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 ...

The set-up process is very simple, and best understood by referring the wiring diagram. If everything goes right,you should see the burning eye of the red LED when there is no object in the safe-zone ...

Uses an ultrasonic sensor to detect hands and triggers a motor to dispense sanitizer automatically. Blink a LED: The most basic Arduino project – toggles an LED on and off at regular intervals.

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.

The LED strip did not work, sadly I think it has something to do with the coding. I am not sure how to get the LED strip in the code without using NeoPixel library or something. But, don’t give up! I ...

First we turn on the trig pin and wait for 15 microseconds and then turn it off, this will send the ultrasonic waves out of this sensor which will get deflected back to the sensor after hitting on the ...

This fun build uses a common off-the-shelf USB “missile launcher” that fires foam darts. To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a ...

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 ...
