66. Automatic faucet (Touchless) using Arduino - Wash hands and stay safe during COVID-19 crisis

Hey friends!

I hope you are all doing well and staying safe now. In this post, I will be explaining you about my prototype which I designed to wash hands safely. I made this project with limited resources. Those who are interested can remake this project, and if you like you can make some improvements too. The codes can be found in the Coding  section of this page. I did not have a solenoid water valve with me, so I had to use the submersible water pump to demonstrate my project.
By having an automatic faucet, you do not have to touch the surface of the faucet after you wash your hands; you can wash your hands safely and prevent coronavirus disease.

Hardware components used in this project

  • Arduino Nano
  • Solderless Breadboard - Half +
  • Ultrasonic sensor
  • Relay module - 5V single channel
  • Submersible water pump (5V) / solenoid water valve (12V)
  • Regulated power supply (optional) - compulsory if solenoid water valve is used
  • Jumper wires

Connections

Ultrasonic sensor

  • Trig - D5
  • Echo - D4
  • VCC - 5V
  • GND - Ground

Relay module - 5V single channel

  • S - D6
  • (+) - 5V
  • (-) - Ground 

How it works


I have programmed my Arduino microcontroller to switch on the relay module when the ultrasonic sensor detects my hand within 10 cm.
If anyone has any questions, please feel free to comment below.

Codes

I have programmed my Arduino microcontroller to switch on the relay module when the ultrasonic sensor detects my hand within 10cm. The submersible water pump is switched on along with the relay module and begins to pump water through the tube connected to it. The tube is led out of the plastic container and acts as a faucet.

51. Buzz wire game using Arduino

Hello everyone! This is my first Arduino project in 2020 and it is going to be a fun and simple project. You would have heard of the Buzz Wire, a steady hand game, and today you will be learning to make one using Arduino. Hardware components used in this project Arduino Nano USB Type A to mini B cable (for Arduino Nano) Solderless Breadboard - Mini and Full-size LEDs (x2) - Green and Red Resistors (x2) - 220 Ω  Active Buzzer module (KY-012) LCD display module with I2C interface - 16x2 Male-to-Male Jumper wires (x4) - 10cm Female-to-Male Jumper wires (x5) - 20 cm Jumpers (x5) - to reduce the usage of wires Copper wire  Tape (or any form of insulation)  Setup Your hardware setup must look somewhat similar to the ones in the images above. The beginning and end of the copper wire maze must be taped to prevent conductivity between the wire loop and maze. Connections LCD display module with I2C interface GND - Ground VCC - 5V SDA - A4 SCL - A5
