Thanks to JLCPCB for sponsoring this video Visit https://jlcpcb.com to get professional PCBs for low prices In this project I will show you how I combined an Arduino Nano, an LCD, a rotary encoder, three peristaltic pumps with motor drivers, a load cell and a couple pieces of wood to create a crude, but functional Cocktail Machine. Along the way I will demonstrate how peristaltic pumps work and in which way they can work with the other components in order to pump a precise amount of liquid.
