How to create an ESP8266 based laundry reminder. Needing a way to remind myself to get my laundry out of the washing machine, I created Laundromat. Using an Adafruit Feather Huzzah and the Pushover app, I get 3 reminders on my phone when my laundry is done.
I have an older washing machine with a green led that lights up when the cycle is complete. Using a light dependent resistor I measure the light level and when it is high or above a threshold I set, it triggers a message to be sent.
This repeats it self for a maximum of 3 times or 3 messages. When the lid of the washing machine is opened the led is turned off.
