The Piezo buzzer produces sound through electricity. Some uses of Piezo Buzzer: e.g clock alarm, alarms, car/truck reversing indicator, bells, timers etc. So we see that this element is used on a wide ...

It combines an Arduino-compatible processor with a light sensor, a temperature sensor, a 3-axis accelerometer, a joystick, a set of pushbuttons, a slider, an RGB LED, and a buzzer.

This project is designed to simulate the traffic light system used in Formula 1 races. It uses an Arduino Nano ATmega328P connected to a breadboard to control the LEDs representing the traffic light's ...

Before opening the Arduino software, wire up the Arduino according to the circuits page using the 8MHz minimalist breadboard circuit but with a 10k pull-up resistor on the reset pin (physical pin 1).
