Today we are adding one more Security Alarm in our list which is based on Ultrasonic Sensor. This Arduino Controlled Door alarm can be installed near the door to detect the presence of anybody at the ...

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 ...

This project is based on Arduino UNO. Distance Alarm is a project that gives us a signal about the particular range of distance. In order to create Distance Alarm we have interfaced an ultrasonic ...

These ultrasonic sensors will send an Ultrasonic wave using the ultrasonic transmitter of the sensor. These ultrasonic waves travel through air and on colliding with an obstacle, get reflected back.

Warning: This is a prototype, some parts need to be improved. Window Arduino Alarm using 2 Ultrasonic Sensors. Menu for the LCD. 0 - STATUS 1 - SETUP ULTRASOUND LEFT 2 - SETUP ULTRASOUND RIGHT 3 - ...

Now, as we know how the components work, let’s go ahead and assemble theses components together and make a circuit as shown below. The Ultrasonic sensor is powered by 5V through Arduino, its trigger ...

Before assembling the circuit, make sure the source code (social_distancing.ino) is uploaded to the Arduino board using Arduino IDE. As shown in the prototype (Fig. 1), all the four HC-SR04 sensors ...

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 ...
