A handy little application to add two digital timers to your favorite Coffeemill. Hardware: Any I2C type Display that supports Adafruit GFX Library, I used a 0.96" OLED Any Incrementaltype Two-Port Encoder with pushbutton or any additional button. The Built-In triggerswitch of your mill or another random pushbutton. Uses arduino´s internal pullup-resistors, so no need to add some but it does no harm to use any. Any sink-powered 5V relais capable of switching your mill motor´s operating voltage and current. Any 5V power supply. I used a ardunio Nano, should work on any other arduino, might need some ajustments on the pin-layout. Used and tested on an Eureka MCI only! Should work for all milltypes using a 230V AC motor.
