In this IoT-based smart bin project, an Arduino Uno R4 WiFi acts as the central control unit, interfacing with two ultrasonic sensors and a servo motor. The power bank provides 5V via the USB-C port, ...

IoT Based Smart Bin. IoT-Based Smart Bin project features a custom-built IoT system and Firebase database, using the Arduino Uno R4 WiFi. Dual ultrasonic sensors handle motion and fill-level ...

For the voice control module, we use a microcontroller LU-ASR01 from China. This requires a special IDE named 天问block(tian wen block) to compile the voice control function. The CodeForVoiceControl.hd ...

Finally, you'll need the trash can itself to pull the whole project together. All in all, you could get this entire build together for under $100 — giving you a much cheaper option than just ...
