This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

In this project, we are interfacing Mercury switch / Tilt sensor with Arduino UNO. We are controlling a LED and buzzer according to the output of the tilt sensor. Whenever we tilt the sensor the alarm ...

Here's an exciting project where we control an LED and a buzzer using a joystick. This project is perfect for beginners looking to explore how inputs like joysticks can interact with outputs like LEDs ...

The circuit of Arduino-based shadow alarm is shown in Fig. 1. It consists of an Arduino board, power supply, light-dependent resistor (LDR) sensor, buzzer, relay driver and a few other components.

The board is suitable for both beginners and advanced users with a convenient port layout that includes a “Maker” connector plus six Grove connectors for sensor modules and a header for four servos ...

The color is converted to the pitch of a sound and the brightness to its duration. Figure 1 shows the schematic of a prototype, with a piezo buzzer and an ams TCS34725 color sensor mounted on a small ...
