Automatic Hand Sanitizer Dispenser (Version 2), Using ATTiny13

As we all know, the COVID-19 outbreak hit the world and changed our lifestyle. In this condition, alcohol and hand sanitizers are vital, expensive, and in some areas hard to find fluids, so, they must be used properly and efficiently. In the second version of the hand sanitizer dispenser device, I have addressed the previous design problems and introduces a device with no sensitivity to the ambient light and flow control capability of the alcohol/sanitizer. Therefore just enough amount of liquid will be poured on each request. The design uses a cheap ATTiny13 microcontroller.
