The tutorial shows the way to develop a bubble logger that enables the user to keep track of the bubbles evolving from drinks. The project is easy to build and use. Read on to know more about this.

The project simply works on the basis of optical gate method of counting bubbles. In addition to the equipment used in the optical gate method, the project has been bundled with an effective pressure sensor and an AVR development board.

Furthermore, an IR photo gate sensor and an airlock have been used in order to obtain a perfect result. To adjust and improve the brightness of the photo gate, a potentiometer has been incorporated as it has the brightness needed to detect the bubble movements.

Additionally, the microcontroller has to be programmed in this case. The only thing that is needed now is a clock. Whenever the bubble is passed through the photo gate, it records the time and bubble count on the serial port.

For further accuracy, time step used for the project was recorded as a whole second, so as to record the exact time of the bubble transition.
