‘subLaundry’ Combines Paho MQTT Python, @IFTTT, and #Arduino for a Laundry Detector #IoTuesday
Sometimes I forget things. In particular, I forget to transfer my clean but wet laundry from the washing machine to the dryer. When this happens, I have to waste time, detergent, electricity, and water to re-wash the clothes. My wife’s sister has an expensive race-car-red washing machine that plays a few cheerful musical notes when the cycle is finished. That reminder is helpful, and my better half likes the little tune, but I figured I could get crafty and make the dumb old washer and dryer whisper in my ear through the internet. Here’s how I did it.
I especially dig the simple solution for attaching the accelerometer sensor to the machine:
Strong enough to stay attached and yet easy enough to remove when needed.
Adafruit LIS3DH Triple-Axis Accelerometer (+-2g/4g/8g/16g): This sensor communicates over I2C or SPI (our library code supports both) so you can share it with a bunch of other sensors on the same I2C bus. There’s an address selection pin so you can have two accelerometers share an I2C bus. Read more.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
