Build your own AI Desk Buddy using the ESP32-C3 and learn how voice-enabled IoT devices work. This DIY educational kit combines an INMP441 MEMS microphone, OLED display, MAX98357A I2S audio amplifier, speaker, capacitive touch sensor, rechargeable battery, and Wi-Fi-enabled ESP32-C3 into a compact smart desktop assistant.
The Desk Buddy captures your voice through the INMP441 microphone, processes and communicates through the ESP32-C3, displays status and information on the OLED, and produces audio responses through the MAX98357A amplifier and speaker. The touch sensor provides an easy way to activate the assistant.
The rechargeable battery and charging circuit allow the project to operate without being permanently connected to USB power.
The project is designed as a hands-on STEM/IoT learning kit for students, makers, and beginners interested in ESP32, I2S audio, sensors, embedded systems, Wi-Fi, and AI-powered applications.
