In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

Description This smart sound alert system illustrate the potential of using Arduino, buzzer and ultrasonic sensor in building a security system. Use case Creating a smart alarm system. Step 1: The ...

This project is a simple, low-cost wearable device designed to assist visually impaired individuals in navigating their surroundings. It uses an Arduino microcontroller, ultrasonic sensor, and buzzer ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...
