Project 2. Halloween trick or treat automata with Voice Recognition module

Introduction: This project employs a voice recognition module, a dfplayer mini, and a servo motor to create a trick or treat automata for Halloween. The Gravity Voice Recognition module by DFRobot, which works offline and can learn new commands, is used to add voice recognition to the project. When activated, the device listens for the 'trick or treat' voice command, then asks questions and waits for responses, with music and servo movements adding to the dramatic effect.

The tutorial includes instructions for setting up the hardware, teaching commands to the module, and downloading the source code.

Project 3. Cool Timer with Voice synthesizer

Introduction: This tutorial guides users through the creation of a voice-synthesized timer designed for hands-free operation, ideal for tasks such as cooking. The device, which uses a DFRobot Gravity DFR0760 module for voice synthesis, is controlled by a single push button. Each press adds a minute to the timer and audibly announces the total time set. A long press resets the counter, while a double click starts the countdown, with the remaining time announced each minute.
