This study, Development of High-Accuracy Dispensing Machines, aims to help bars,
restaurants, and pubs. This prototype can dispense multiple liquids at a time with different
kinds of liquor. Currently, industrial liquid dispensing equipment is expensive, complex,
and challenging to design and build. The main requirement for this machine is its
measurement or quality assessment. Automated processes have taken on the role of human
approaches in the modern period, which is distinguished by a high need for precise,
accurate, and time-efficient solutions. It has five major parts: the container, which stores
the liquid that is to be dispensed. The electronic system has an Arduino Nano, which stores
the program in C++ for the automation of the prototype. The dispensing component uses a
peristaltic pump for accuracy and to avoid contamination of the liquids. The prototype was
tested by dispensing pump 1 to pump 3 from 10 ml to 100 ml by single dispensing, and the
next trial would be dispensing 2 combined nozzles, which are 1 and 2, 2 and 3, and lastly,
1 and 3. The prototype was evaluated by 27 respondents who are experts in the field of
automation and for dispensing accuracy. The grand mean was rated 4.80. The researcher
also provided testing for dispensing the three nozzles at the same time. This prototype has
proven its functionality; however, it can only dispense liquids with low viscosity and can
be used inside the facilities because it needs a power source to work.
