Project: ESP32-Based Talking Plush Toy – Prototype Development Project Overview I’m building a screen-free talking plush toy for kids (3–7 years). The goal is to create a working prototype (V1) that demonstrates: Calm audio interaction Simple button & Bluetooth (BLE) control Safe, battery-powered operation This is prototype-only, not mass production. Scope of Work The freelancer will: Build a working ESP32-based prototype Implement audio playback (pre-recorded voice files) Support button-based triggers Implement BLE connectivity (basic commands from phone) Ensure safe power & insulation for a prototype Share code + wiring diagram + build instructions Core Features (V1) ESP32 dev board Pre-recorded audio playback (stories, phrases) 1–2 physical buttons BLE commands from mobile app (play audio / change mode) Battery-powered (AA/AAA, no lithium battery) Speaker + amplifier On/Off switch Deliverables 1 working electronics prototype (bench-level) Arduino/ESP32 source code Simple BLE protocol description Wiring diagram List of components used (BOM) Short demo video of working prototype

Hi. I can develop your V1 talking plush prototype using an ESP32 with a DF Player Mini (MP3 module) and speaker for reliable pre-recorded audio playback. The ESP32 will handle button-triggered interactions and basic BLE commands from a mobile app (play audio/change mode), while the DFPlayer Mini ensures simple, stable audio control. The system will be safely powered by batteries with proper insulation and an on/off switch. Deliverables include a fully working bench-level prototype, complete ESP32 source code, wiring diagram, BLE command documentation, BOM, build instructions, and a short demo video. I am looking forward to collaborate with you.
