Daughter board
About the Daughter board
Daughter board is an open source PCB design by 97Cweb, published on GitHub. It is a 2-layer board measuring 20 × 10.8 mm, with 3 components from 3 distinct parts.
Other key parts include the GP1S094HCZ0F. By type, the board carries 1 IC, 1 connector and 1 resistor.
It belongs with the audio designs in this gallery.
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.
