About the Dryer Buzzer V3 PCB

Dryer Buzzer V3 is an open source AVR/Arduino PCB design by 97Cweb, published on GitHub. It is a 2-layer board measuring 47.7 × 50.8 mm, with 8 components from 7 distinct parts.

Its main chip is the Arduino_Nano_v3.x, from the AVR/Arduino family. By type, the board carries 3 connectors, 3 resistors, 1 module and 1 capacitor.

It belongs with the audio designs in this gallery, and the repository also holds 1 earlier revision of it.

From the project

An Arduino project based on adding a buzzer to a washer and dryer on the same board

A thing to build to put buzzers back on the washing machine and dryer

V1 used a photoresistor on the washing machine V2 uses 2 optocouplers to get the washing machine knob position.

Both use a non invasive current sensor for the dryer to get whether it is on or not.

You will also need a speaker module to get enough volume from the audio.

Dryer Buzzer V3: common questions

What microcontroller does the Dryer Buzzer V3 use?

The Dryer Buzzer V3 is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Dryer Buzzer V3 PCB?

The Dryer Buzzer V3 measures 47.7 × 50.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dryer Buzzer V3?

8 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Dryer Buzzer V3 design files?

From the 97Cweb/Washer-Dryer-Buzzer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Dryer Buzzer V3 design in my own project?

The repository has no license, so all rights stay with 97Cweb. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Dryer Buzzer V3 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
