How to make an automatic garbage can with Arduino Nano

26 August 2024 2 minutes

Creating an automatic garbage can that opens on its own is a fun project for the electronics enthusiast. Using an Arduino Nano, an HC-SR04 ultrasonic distance sensor, and a servo, you can easily assemble a system that will open the lid of the tank when approached.

Required components:

Connection diagram

Servo drive

  • Red Dirt → 5V Arduino
  • Black → GND Arduino
  • White → Arduino pin D6

Ultrasonic distance sensor HC-SR04

  • VCC → Arduino 5V pin
  • GND → Arduino GND pin
  • TRIG → pin D2 Arduino
  • ECHO → pin D3 Arduino

Accumulators

  • connect the + battery to the VIN pin
  • battery to the GND pin

Note that the input voltage must be in the range of 7 to 12 volts.

Firmware

**If you do not have the Arduino IDE installed, I advise you to watch the video tutorial, which shows how to install and configure it. At this link you will find information on how to install the driver on the Arduino board.**

Download the firmware from this link and upload it to the Arduino according to the instructions above.

Importantly

You need to flash the Arduino before connecting all the components. If batteries or other parts are connected to it during the firmware, you risk burning (literally) your computer and Arduino.

Principle of operation

We hope that everything worked out for you! The sensor measures temperature and humidity, transmits this data to the Arduino, which in turn displays it on the display.
