In the most basic terms, an espresso machine works by using steam, pistons, or pumps to force hot water through the puck of coffee beans. The high pressure inside an espresso machine and the low water ratio to coffee give espresso its distinctive thick consistency. This project makes a use of Arduino uno microcontroller, the main controlling device of the project. Two DS18B20 temperature sensors are uses to measure the temperature values at STEEM and inside of the container. LCD display is uses to display the temperature values on it. Two DS18B20 temperature sensors and LCD display is interfaced to the Arduino UNO microcontroller. Arduino uno will continuously measure the temperature values from sensors and will be display on LCD module.

 

The major building blocks of this project are:

1. Adapter power supply.
2. Arduino UNO Micro controller.
3. DS18B20 temperature sensors.
4. LCD display.

Software’s used:

• Arduino IDE programmer for dumping code into Micro controller.
• Express SCH for Circuit design.
