Arduino Sticker Dispenser Saves Time

The most cumbersome aspect of packaging identical items often lies in applying warning stickers to the shipping boxes. However, an innovative solution comes from Mr Innovative, who has created an open-source automatic sticker dispenser to streamline this process. Constructed primarily from 20×20 extruded aluminum and stainless steel smooth rods, with the yellow components 3D printed, the device utilizes an Arduino Nano and an A4988 stepper motor driver to control a NEMA17, making the sticker application a satisfying and automated task.

A notable feature of this dispenser is the implementation of an infrared (IR) sensor pair positioned beneath the sticker ready for application. When a sticker is removed, the sensor detects the change, prompting the stepper motor to advance the roll by one sticker height. Waste stickers are efficiently collected on a spool located underneath the system. The combination of robust hardware and clever sensor integration enhances the overall efficiency of the dispenser.

For those intrigued by this project, Mr Innovative has provided both a detailed video demonstration and comprehensive instructions, making it accessible for anyone interested in building their own automated sticker dispenser. The simplicity of the design, coupled with the open-source nature of the project, invites enthusiasts to explore and replicate this innovative solution for their own packaging needs.
