I am seeking a skilled freelancer who must be in the UK to develop a project utilizing the ESP32-S3 and a breadboard setup. The task involves constructing a fully functional device that listens for up to 10 specified trigger words using an omnidirectional microphone. Upon detecting a trigger word, the device will activate a buzzer and flash an LED. The project must be powered by a lithium polymer battery and designed for independent operation, without relying on Wi-Fi or Bluetooth connectivity. The final product should be shipped to me in a ready-to-use state.
