DIY Automatic Alcohol Dispenser ($3 No Arduino Needed)

Build the only $3 Automated Alcohol Dispenser with out utilizing Arduino. Keep your fingers clear by filling it with liquid cleaning soap, hand sanitizer or with rubbing alcohol. By decreasing bodily contact, an automatic dispenser retains virus from spreading round in communal areas.


I’ve seen a number of Arduino automated liquid dispensers circulating the online. I discover utilizing Arduinos a bit overkill for this particular challenge. Arduinos are far too costly. I figured utilizing a easy transistor or MOSFET would do the job, which might additionally drastically scale back the prices. Obviously, the absence of a micro controller removes management of over spilling, however then, I did discover out that utilizing a smaller nozzle would bodily restrict the move of liquid. There are a number of two transistor RC circuits that may resolve the over spilling drawback however the single transistor design works effectively, given that you simply select the right nozzle measurement.
