The digital coffee machine

In my final project in Electronics A at HTX Hillerod, I developed an automatic coffee machine. By programming an Intel MCS-51 microprocessor in Assembler and using 3 DC motors, the machine was able to measure a precise amount of coffee, milk and sugar into a mug. The proportion of each ingredient could be set using a few buttons and a 2x16 LCD display on the front of the machine. Boiling water was then added, and the coffee served. I also used an Arduino Uno with an Ethernet Shield to control the machine via the internet. By writing a simple PHP application to keep track of orders, the coffee machine could now be controlled from any computer, tablet or smart phone.
