An ESP32-powered cardboard monster head dispenses Halloween candy on demand. Builder Christian used a stepper motor with a finger wheel to move candy, an IR break beam to confirm each dispense, and a triggered light and sound array to sell the effect. The nose is the button. The whole thing is documented and published on GitHub under the project name Halloween Candy Monster Celebration Dispenser.
The hardware choices matter here. The IR break beam adds actual feedback to the dispense loop, meaning the system knows whether candy moved, not just whether the motor turned. That distinction separates a toy from a reliable mechanism, and it is worth reading the repository to see how Christian handled the detection logic alongside the stepper control on a single ESP32.
This is not the first candy dispenser Hackaday has covered. A Halloween vending computer with voice interaction appeared in September 2025. The pattern is real: low-cost microcontrollers and hobby mechanics are converging on a specific, silly, and genuinely instructive problem space. Worth watching where it goes.
