A device helping you fight the Corona virus by avoiding contact with the tap.

This is a code for a device that can help you fight Corona virus by turning the water on and off for you, without the need to touch anything. It uses Arduino, servo motor, ultrasound sensor, a stick, and shitload of ductape.

You can watch a video of the Corona Fighter in action.

• Connect servo to pin 6
• Connect trigger of ultrasound sensor to pin 7
• Connect echo of ultrasound sensor to pin 8
• Load the code
• Wave with your hand in front of it

Use of Corona Fighter will NOT make you invulnerable to Corona virus! It will only help. Don't assume perfect safety, use responsibly!

Use more ductape.

• The device sometimes triggers on its own right after start
• The code is in unsafe language. Fortunately Corona wasn't observed exploiting C++ yet, so this should be fine. In case such thing happens in the wild, I will rewrite it in Rust.
