Rhythm Machine

Create programmable rhythm patterns with a buzzer

Watch the circuit build itself: components drop in, wires connect, and the output comes alive.

Components

Everything you need for this project.

1x Passive buzzer

2x Tactile push buttons

10KΩ

2x 10KΩ resistors

1x Green LED

220Ω

1x 220Ω resistor

6x jumper wires

How It Works

Arrays and sequences, PWM frequency control, user input handling, combinational logic, and creative expression through technology.

Input2 Push Buttons
ProcessingESP32-S3 records beat pattern, loops playback
OutputBuzzer rhythm + LED beat

What You Build

Two buttons for beat input on D1/D2, buzzer on D3, LED on D4. Record a rhythm pattern, play it back in a loop.

African Context

Music and rhythm are central to African culture. This project connects technology to creative expression: beatboxing through circuits.

What You'll See

Press buttons to record beats. Playback loops the pattern through the buzzer with visual beat indicator on LED.
