This Arduino project creates a simple ticking sound reminiscent of an analogue clock, producing one tick per second.
The circuit works by sending brief electrical pulses to a piezo buzzer or speaker, creating audible clicks at regular intervals. When the digital pin goes HIGH, it sends a 1-millisecond pulse to the speaker, producing a short, sharp sound. The system then remains silent for 1000 milliseconds (1 second) before repeating the cycle, mimicking the familiar rhythm of a ticking clock.
Parts List
- Arduino board
- Jumper wires
- Piezo buzzer or small speaker
Assembly Instructions
- Connect the positive (longer) leg of the piezo buzzer to digital pin 11 on the Arduino board.
- Connect the negative (shorter) leg of the piezo buzzer to the GND (ground) pin on the Arduino board.
- Optional: If the ticking sound is too loud, place a 100-220 ohm resistor in series with the buzzer.
