Mixing up perfect, custom cocktails often requires months or even years of training, in addition to having to know a plethora of recipes. But Jithin Sanal wanted to pour his favorite drinks without spending the extra time and effort, so he concocted a robotic cocktail mixer to perform this task for him. It operates by using a series of ingredient reservoirs, pumps, an Arduino Nano RP2040 Connect, and a few relays to dispense a precise quantity of the desired ingredient into a container. Sanal also designed and fabricated his own circuit board to connect each component together in a circuit.

Rather than having a bunch of physical buttons on the front of the robotic cocktail mixer, Sanal instead opted to use the Arduino Cloud with five virtual ones that each correspond to a single drink. When a button is pressed, a function is executed on the Nano RP2040 Connect that activates the correct pumps in the specified order for a certain duration. By utilizing this method, users can be confident their drink is perfectly made every single time. More drinks can be added to the system simply by adding another button within the Cloud and creating the associated function in the RP2040’s code.
